Definition
A CometAPI pricing reconciliation incident review is a time-bounded investigation that compares your captured request usage, the pricing assumptions in force during the window, and the charges or account records you received. The goal is not just to find a variance; it is to preserve evidence, identify the contract assumption that failed, and produce a repeatable remediation.
Key takeaways
- Treat the pricing source, API contract, request logs, and billing export as separate evidence streams.
- Do not rely on copied spreadsheet rates without checking the current CometAPI pricing source at review time.
- Capture the incident window, timezone, model or service identifiers, request IDs, usage dimensions, and the exact source documents used.
- Recompute charges from raw usage where possible, but label every pricing rate, rounding rule, and billable field as “verified,” “inferred,” or “unknown.”
- If the discrepancy depends on undocumented behavior, prepare a focused support packet using the CometAPI Help Center rather than sending a broad billing complaint.
Scope for the 2026-05-11 review
Use this checklist when the incident question is one of these:
- “Why did CometAPI spend exceed the forecast for this window?”
- “Did our local token ledger use the same billable units as CometAPI?”
- “Did a pricing assumption, model alias, retry policy, or request field change our expected cost?”
- “Can we show enough evidence to escalate a billing question?”
The supplied public evidence for this draft is the CometAPI API documentation home, the CometAPI pricing information page, and the CometAPI Help Center: API documentation, pricing information, and Help Center. This article does not assert current rates, supported models, quotas, or billing guarantees beyond what an operator verifies from those sources and their own account records.
Incident evidence packet
Before changing dashboards, retry settings, or model routing, freeze the following artifacts.
| Artifact | Minimum fields to capture | Why it matters |
|---|---|---|
| Incident window | Start time, end time, timezone, deploy IDs, feature flags | Prevents mixing normal spend with incident spend |
| Pricing source snapshot | URL, capture time, model or service label, unit of measure, currency if shown | Establishes which rate card or pricing rule you used |
| API contract snapshot | Endpoint path, request fields, response fields, auth mechanism, error format | Detects mismatches between your integration assumptions and documented behavior |
| Raw request logs | Request ID, timestamp, endpoint, model/service, tenant, status, retry count | Supports request-level or aggregate reconciliation |
| Usage ledger | Input units, output units, cached units if tracked, request count, tool calls if tracked | Lets you recompute expected charge by billable dimension |
| Billing/account export | Charge line, date bucket, service/model label, invoice or account ID | Provides the provider-side number to reconcile against |
| Incident notes | Timeline, owner, decisions, unresolved assumptions | Keeps the review auditable |
If a field is not available, record that explicitly. An “unknown” field is better than a silently inferred field.
Practical validation workflow
1. Pin the incident window
Define the smallest useful window first, then widen only if the variance remains unexplained.
Recommended fields:
incident_start_utcincident_end_utc- local timezone used by finance reports
- deployment or configuration changes during the window
- model routing, retry, fallback, or batch job changes during the window
Example threshold: start with the period where observed spend differed from forecast by more than your internal alert threshold, then add 30 to 60 minutes on each side for queued jobs and delayed reporting. Tune that buffer to your workload; do not treat it as universal.
2. Reconfirm the pricing source
Open the CometAPI pricing information page during the review and record the source URL: https://apidoc.cometapi.com/about-pricing-873788m0.
Capture:
- source URL
- access timestamp
- model, service, or product identifier as written on the source
- billing unit
- currency, if shown
- any tier, discount, package, or account-specific note visible to the operator
- screenshot or exported copy, if allowed by your internal policy
Do not use this draft as a price source. Use it as an evidence checklist.
3. Reconfirm API contract assumptions
Use the CometAPI API documentation home as the entry point for endpoint and field verification: https://apidoc.cometapi.com/.
For each affected integration path, verify:
- exact endpoint path used by the application
- authentication header name and format
- request field names and defaults
- response usage fields
- error response shape
- retryable versus non-retryable conditions
- whether your client retried, duplicated, or resumed requests
The purpose is to find cost deltas caused by integration behavior, not just pricing deltas.
4. Normalize usage dimensions
Create a reconciliation table with one row per pricing dimension. Do not collapse everything into “tokens” unless the pricing source uses that exact unit.
Common dimensions to check, where applicable:
- request count
- input units
- output units
- cached or discounted units
- batch units
- tool-call or multimodal units
- failed, cancelled, or retried requests
- streaming responses completed after client disconnect
Label each dimension as:
verified_from_responseverified_from_server_logderived_from_payloadestimatedunavailable
Only use estimated fields for impact ranges, not final variance claims.
5. Recompute expected charge
For each billable dimension:
- Select the usage quantity for the incident window.
- Select the matching pricing rate from the captured pricing source.
- Convert units consistently.
- Apply rounding only if the billing rule is documented or visible in account records.
- Compare your expected charge with the provider-side or account-side charge.
Formula pattern:
expected_charge = sum(billable_quantity × applicable_rate ÷ published_unit_size)
If the pricing source uses a different structure, use that structure instead. The formula above is an operator pattern, not a CometAPI contract.
6. Separate variance causes
Classify the variance before assigning ownership.
| Variance class | Example signal | Operator action |
|---|---|---|
| Pricing-source mismatch | Spreadsheet rate differs from pricing page or account record | Replace stale rate source and backfill affected estimates |
| Usage-capture gap | Local logs omit retries, streaming completions, or background jobs | Fix instrumentation and rerun reconciliation |
| Field interpretation gap | App reads a field differently from documented response semantics | Update parser and add regression test |
| Time-window mismatch | Finance report uses a different timezone or aggregation delay | Align reporting calendar and rerun |
| Account-specific billing issue | Recomputed charge still differs after contract and usage checks | Prepare support packet through the Help Center |
| Unknown | Required fields are missing or undocumented | Mark unresolved and define next evidence request |
7. Validate with a second computation path
Use at least two independent computations before closing the incident:
- application request logs aggregated by request ID
- warehouse usage ledger aggregated by time bucket
- billing or account export aggregated by charge line
- sampled replay of usage records without sending live API requests
The two paths do not need to match perfectly, but the residual variance should be explainable. Example tolerance bands such as 1% or a fixed dollar amount should be set by your finance owner and workload size; this draft does not define a universal tolerance.
Sanitized reconciliation record example
Use a structured record so a reviewer can reproduce the calculation without seeing secrets, user prompts, or full payloads.

Contract details to verify
This table is intentionally verification-oriented. Fill the “observed value” column from your integration and the cited CometAPI source before making billing conclusions.
| Contract item | What to verify | Observed value in your incident | Why it affects reconciliation | Source to check |
|---|---|---|---|---|
| Endpoint paths | Exact path called by the application, including version prefix and operation | Fill from gateway logs | A different endpoint can imply different request fields, response usage fields, or billing dimensions | CometAPI API documentation |
| Auth headers | Header name, token scheme, account/project scoping, and whether multiple credentials were active | Fill from secret inventory and sanitized request metadata | Mis-scoped keys can attribute spend to the wrong account, project, or ledger | CometAPI API documentation and Help Center |
| Request fields | Model/service identifier, streaming flag, tool or modality fields, max-output controls, retry metadata if sent | Fill from sampled sanitized requests | Request options can change usage volume or routing assumptions | CometAPI API documentation |
| Response fields | Usage object, request ID, status, finish reason, error object, and any billable usage fields | Fill from stored responses or middleware logs | Your local ledger depends on response fields being parsed correctly | CometAPI API documentation |
| Error behavior | Status codes, retryability, partial responses, timeout behavior, and whether the client retried automatically | Fill from client logs and retry library config | Retries and partial completions can create usage not visible in business-level request counts | CometAPI API documentation and Help Center |
| Rate-limit or billing assumptions | Pricing unit, rate source, account-specific terms, reporting delay, rounding, minimums, discounts, and whether failed or retried calls are billable | Fill from pricing source, account export, and support response | These assumptions directly determine expected cost and whether a variance is real | CometAPI pricing information and Help Center |
Incident review checklist
Evidence capture
- Assign one incident owner and one finance reviewer.
- Record incident start and end time in UTC.
- Record the local finance timezone separately.
- Capture the CometAPI pricing information page used for the review.
- Capture the API documentation pages relevant to affected endpoints.
- Export or snapshot account-side billing records available to the operator.
- Preserve raw gateway logs for the incident window.
- Preserve application-level request logs.
- Preserve deployment, feature-flag, and configuration-change history.
- Record all assumptions that cannot be verified from public docs or account data.
Usage validation
- Count successful requests.
- Count failed requests.
- Count retried requests.
- Identify duplicate client requests caused by timeout or queue replay.
- Identify scheduled jobs, batch tasks, or backfills that ran during the window.
- Compare request IDs between gateway logs and application logs.
- Compare response usage fields with warehouse usage records.
- Check whether streaming responses were logged after completion or only at start.
- Check whether any requests crossed the incident window boundary.
- Mark sampled records that cannot be tied to a charge line.
Pricing validation
- Confirm the exact service or model label used in application requests.
- Confirm the matching label on the pricing source.
- Confirm the billable unit.
- Confirm whether input and output units are priced separately, if applicable.
- Confirm any discount, package, or account-specific term from account records.
- Confirm currency and reporting period.
- Confirm whether your internal forecast used the same pricing source.
- Recompute expected charge from raw usage.
- Compare against provider-side account records.
- Document every remaining unknown.
Remediation
- Update the pricing source of truth if a stale internal rate was used.
- Add a parser test for any response usage field involved in the variance.
- Add a deployment guard if a feature flag or model route caused the spike.
- Add a retry budget if automatic retries amplified cost.
- Add a reporting alert for the earliest detectable signal.
- Prepare a support packet if account-side records remain inconsistent.
- Record the final variance, owner, and prevention action.
When to escalate through support
Use the CometAPI Help Center when your evidence shows a remaining provider-side question after you have reconciled your own logs and assumptions: https://apidoc.cometapi.com/help-center.
A focused support packet should include:
- account identifier, if safe to share
- incident window in UTC
- affected endpoint paths
- affected service or model labels
- request IDs or charge-line IDs, if available
- sanitized usage rollup
- pricing source URL and capture time
- expected charge calculation summary
- provider-side charge or billing record being questioned
- exact question you need answered
Avoid sending raw prompts, API keys, customer data, or unrelated logs.
Closure criteria
Close the incident only when all of the following are true:
- The variance is explained or formally marked unresolved.
- The evidence packet contains the pricing source, API contract source, usage rollup, and billing comparison.
- Any undocumented assumption has an owner and follow-up action.
- The finance reviewer agrees with the final impact statement.
- Prevention work is tracked separately from the investigation notes.
A good final statement is specific:
“Between 08:00 and 10:00 UTC on 2026-05-11, expected CometAPI spend differed from account-side reporting by X. Y was explained by retry amplification after timeout changes. Z remains unresolved pending support confirmation on rounding behavior. Parser test and retry budget follow-ups are linked.”
FAQ
Does this checklist provide current CometAPI prices?
No. It tells you how to verify prices. For pricing evidence, use the CometAPI pricing information page and your account records: https://apidoc.cometapi.com/about-pricing-873788m0.
Should we assume a machine-readable pricing API exists?
No. Do not assume a pricing endpoint, response schema, or automation path unless it is documented in the CometAPI API documentation or confirmed through support. This draft only cites the public documentation and pricing pages supplied as evidence.
What if our token counts do not match the provider-side charge?
First check whether you are comparing the same window, service label, and billable dimensions. Then inspect retries, failed requests, streaming completions, and parser behavior. If the gap remains after local validation, prepare a support packet with sanitized evidence.
What variance threshold should trigger an incident?
Use a threshold set by your finance and platform teams. A small absolute variance may matter for a low-budget tenant, while a small percentage variance may be normal for high-volume workloads. Treat any example threshold as a tuning starting point, not a universal rule.
Can we rely on screenshots of the pricing page?
Screenshots are useful evidence, but they are not enough by themselves. Record the URL, access time, visible unit of measure, account context, and the person who captured it. Pair the screenshot with your raw usage and billing export.
What is the most common reconciliation mistake?
The most common operational mistake is mixing evidence types: using one timezone for usage logs, another for finance exports, and a stale spreadsheet for pricing. Keep each source separate until you normalize the data.
