Direct answer

A CometAPI key quota audit should check the credential actually used by a workload, its unlimited_quota flag, remaining quota, expiration, and model-restriction settings. Compare those observations with an approved policy before changing anything. A positive account balance does not establish that a particular key has usable quota, and a numeric remaining-quota value does not establish that quota checks are enabled.

The current-key reference defines unlimited_quota as whether the key bypasses remaining-quota checks. Enabling it therefore changes a financial control. Treat that change as an explicit exception with an owner, an end condition, and another enforceable workload allowance where needed. The flag concerns remaining quota; it does not establish unrestricted model access or unlimited account funds.

For example, a sandbox stops working while the shared account still has funds. An operator follows troubleshooting advice and enables unlimited quota. The application recovers, but its former remaining-quota check has been bypassed. The audit must capture both outcomes. CometAPI’s Common Misconceptions page explicitly distinguishes account balance from token quota and recommends unlimited quota when troubleshooting quota-related failures. Restoring access and approving the resulting spending exposure require separate decisions.

Who this is for

This guide is for platform engineers and budget owners who issue CometAPI credentials to sandboxes, internal tools, or shared services. It is especially useful after a quota-related incident, credential rotation, or dashboard change.

The workflow below is a recommended audit procedure based on public documentation. No authenticated account inspection, quota-exhaustion test, or billing experiment was performed for this article. Verify finite-quota behavior for your selected request path before relying on it, and keep account-specific observations separate from documented field meanings.

Key takeaways

  • Inspect the bearer key used by the application; a dashboard label alone cannot prove which credential a worker loaded.
  • Evaluate unlimited_quota before interpreting remaining quota as an active restriction.
  • Keep current-key internal quota units separate from USD balance measurements.
  • Preserve documented sentinel values, including -1 for unlimited quota in the query-service fields.
  • Read back configuration after changes and rotation, then test the intended behavior on an isolated workload.
  • Treat monitoring failures as unknown state and require approval before removing a financial restriction.

Contract details to verify

Read each field in its documented scope

The current-key endpoint is GET /api/usage/token on api.cometapi.com. It authenticates with the CometAPI API key in a Bearer header and reports on that key. Its reference distinguishes this credential from the separate personal access token used for key-management endpoints. An audit does not need to grant its ordinary monitoring process authority to create or edit keys.

The balance and usage reference describes a separate query service. These two response formats need different interpretations:

ObservationDocumented meaningAudit treatment
Current-key total_granted, total_used, total_availableAmounts in CometAPI internal quota unitsRetain the unit label; do not display these integers as dollars or model-token counts
Current-key unlimited_quotaWhether remaining-quota checks are bypassedCompare the boolean with the approved policy, even when a remaining amount is present
Current-key expires_atUnix seconds; 0 means no expiration in this usage responseApply this endpoint’s sentinel and compare any finite timestamp with the intended expiry
Current-key model_limits_enabled and model_limitsActivation flag and model-restriction mapCapture both and compare them with the approved configuration
Query-service total_quota and total_used_quotaCurrent account balance and cumulative usage in USDKeep them as account measurements, separate from the current-key integers
Query-service per-key quota value -1Unlimited quotaPreserve it as a distinct state instead of converting it to zero

Do not invent a conversion factor between the two endpoints. Establish any needed mapping from current account documentation or support evidence before producing a dollar limit from internal units. Likewise, a cumulative account counter is not automatically this month’s workload spend. A report needs a defined period and attribution method.

Resolve the unlimited-quota advice deliberately

The troubleshooting page recommends setting tokens to unlimited quota. The balance-query guide, meanwhile, recommends a dedicated query key and, to limit exposure, disabling Unlimited Quota and choosing the smallest positive credit limit allowed by the dashboard. These instructions address different operating tasks.

For monitoring, follow the dedicated-key guidance and verify that the query works with the chosen setting. Do not describe a small positive quota as a read-only permission: the cited guide recommends reducing exposure, not a monitoring-only authorization scope. For model traffic, verify whether the finite setting supports the intended calls. If it does not, stop the rollout or open a bounded exception rather than silently changing every application key to unlimited.

The cited references do not establish a strict dollar cap, concurrent-request overshoot bound, monthly quota reset, or propagation delay for a key change. Record those as unverified unless account evidence establishes them. A configuration readback proves what the endpoint reported at that moment; the acceptance checks establish how your application reacts.

Establish a baseline before editing

Start with one nonproduction workload. Record its owner, environment, secret-store reference, approved quota mode, expected expiration policy, and exception reference if applicable. Use a stable internal key alias in the audit record. Maintain the connection between that alias and the deployed secret version in restricted configuration; do not use the raw credential as an identifier.

Inspect the current-key endpoint using the credential that the workload actually resolves. Require both a successful HTTP response and the documented successful response envelope, including code: true. Validate the expected field types before evaluating policy. An absent boolean must not default to false, because that could make missing evidence resemble an enabled quota restriction.

Compare unlimited_quota, expiry, and model settings with policy. An expected finite quota paired with unlimited_quota: true is a mismatch even if total_available looks adequate. An expiration requirement paired with expires_at: 0 is also a mismatch. Keep quota size and expiration as independent checks: a short-lived credential can still create substantial usage before it expires.

Capture the account’s USD balance separately if funding is part of the review. The account guidelines state that the final call can make the balance negative when its cost exceeds the remaining funds. A small wallet balance therefore does not establish a zero-overrun boundary. Decide how much exposure the workload may create before depending on account exhaustion as a stop.

Read back changes and contain exceptions

Route quota increases and unlimited-quota changes through budget change control . State the reason, affected workload, approving owner, temporary allowance, and rollback condition. Keep production keys outside an experiment’s approval scope.

After an authorized edit, fetch the current-key state again through the deployed application’s credential path. Repeat this check for each distinct secret version still in service. A successful inspection of the replacement key does not prove that old workers stopped using the previous one. Complete the normal rotation process and verify the actual consumers before closing the change.

An unlimited exception needs an independent control that can stop new work. For parallel workloads, use the existing atomic budget reservation design to account for outstanding commitments before dispatch. Keep retries and alternate credentials inside that scope. An alert without a working response path cannot replace the quota check that was removed.

For an unattended sandbox, a practical local policy is to pause new dispatch when required audit data becomes unavailable or fails validation. Production services need their own reviewed degradation policy. In either case, retain the last successful observation with its age and label the new state unknown; never overwrite it with zero consumption or a fabricated healthy result.

Smoke-test workflow

Before testing, choose an isolated key, one approved small request, a bounded test allowance, and an operator who can stop the workload. Disable automatic credential switching for the test. The following are acceptance criteria to run in your environment, not reported outcomes:

CheckRequired evidence
Approved finite configurationCurrent-key readback matches policy; one bounded request behaves as expected and has a corresponding usage record
Unexpected unlimited flagThe policy evaluator identifies the mismatch and pauses new sandbox work or invokes the approved exception path
Failed or malformed inspectionThe result becomes unknown, the owner is alerted, and the workload follows its configured degradation policy
Rotation with an old workerInspection identifies the old secret version; the change remains open until the consumer is replaced or stopped
Query-service -1 valueThe report shows unlimited quota without an exhaustion alert or a false zero-spend conclusion
Finite-quota exhaustion, where safely testableThe application records the observed failure and stops; it does not automatically retry through an unrestricted key

Use an already exhausted isolated test key for the exhaustion check when available and supported. Do not consume a production allowance repeatedly to discover the boundary. Record the observed response classification without assuming a particular HTTP status. If safe verification is unavailable, mark exhaustion behavior unverified and retain another dispatch control.

The audit event should include observation time, internal key alias, deployed secret version, policy version, returned flags, quota units, decision, and evidence reference. Keep credentials, authorization headers, full query URLs, and raw response bodies out of general logs. The query-service reference places its authentication credential in a query parameter, so its request URL requires particular care.

An illustrative mismatch record could be:

{
  "evidence_kind": "illustrative",
  "key_alias": "sandbox-summaries",
  "secret_version": "version-b",
  "policy_mode": "finite-required",
  "unlimited_quota": true,
  "total_available": 100000,
  "quota_unit": "cometapi-internal",
  "decision": "pause-new-sandbox-work",
  "reason": "unlimited-quota-policy-mismatch"
}

The numeric amount does not override the boolean mismatch. This record also avoids pretending that the integer represents a USD allowance.

Failure modes

Troubleshooting silently removes the restriction. A key starts working after unlimited quota is enabled, so the incident is closed without financial review. Reopen the configuration change, assign its exception owner, and establish the replacement control before increasing traffic.

Monitoring uses the production credential. A reporting worker gains access to a broadly usable key unnecessarily. Use the dedicated query credential recommended by the balance guide, verify its smallest practical positive limit, and restrict who can retrieve it. Do not promise that its quota setting makes leakage harmless.

An account top-up is treated as a key-policy repair. Funding and key quota are independent in the troubleshooting reference. Reinspect both instead of assuming that a deposit established the intended key configuration.

A snapshot is treated as a reservation. Several workers can read the same observation before any new usage appears. Use a shared admission control when the workload needs an enforceable allowance; polling alone does not reserve money for a request.

Audit failure becomes an automatic quota edit. A missing field or transport error triggers an attempt to enable unlimited quota. Keep the observer read-only and send unknown state through the reviewed response policy. A monitoring failure supplies no evidence that a restriction should be removed.

FAQ

Why can a key fail when the account still has funds?

CometAPI documents account balance and token quota as independent. Inspect the actual key and its quota settings before changing funding or permissions. A positive wallet balance alone cannot explain every authentication, routing, or quota failure.

Does unlimited quota remove model restrictions?

The current-key reference defines the unlimited flag specifically as bypassing remaining-quota checks. It reports model restrictions separately. Inspect their activation flag and map independently, and verify the permitted request path.

Does a finite key quota automatically reset every month?

The cited current-key reference does not document a monthly reset contract. If the business needs a monthly allowance, define its period and reset policy explicitly and verify any provider feature used to implement it.

Can we call a numeric quota value a hard spending cap?

Only after establishing its units, enforcement scope, covered charges, and behavior around outstanding calls. The documented fields alone do not establish all those boundaries. Describe what was verified and retain additional controls for unresolved exposure.

Reader next step

Choose one sandbox key and write its expected quota mode before opening the dashboard. Read back the deployed credential, compare every policy field, and run the bounded happy path plus the unexpected-unlimited check. Assign any exception a financial owner and a removal condition, using the site’s shared-access ownership workflow where several teams share the route.
