Direct answer
Store CometAPI text results as an audit record, not just a generated string. A safe first schema separates request identity, endpoint family, submitted payload summary, response envelope, selected output text, usage fields when present, error envelope when present, and verification notes. Keep raw payload storage optional and controlled, because the official references show useful response and error structures while also noting that request parameters and response fields can vary by model provider.
A practical result table should start with a local run identifier, application environment, endpoint family, request timestamp, HTTP status, outcome, response identifier when returned, parser path used to extract text, selected text, usage object when returned, sanitized error object when returned, redaction status, and a short note. That list gives future maintainers enough evidence to understand how a saved text value was produced without turning the database into an unfiltered transcript store.
A practical smoke-test workflow:
- Setup assumptions: use a test API key stored outside source control, a non-production project, a placeholder model selected from the current docs or dashboard, and a database table dedicated to test records.
- Happy-path request plan: send one minimal text request to the documented chat or Responses interface, then store the endpoint family, request timestamp, HTTP status, response identifier when returned, selected text path used by your parser, usage object when returned, and a short parser verdict.
- Error-path check: send a deliberately incomplete test request in the same environment and store the HTTP status, error object shape, error type or code when returned, and whether the client redacted credentials before logging.
- Minimum assertions: the record has a unique local run id, no credential values, an endpoint family label, a request timestamp, a success or error outcome, and enough response-shape evidence to replay the parser decision.
- Pass/fail logging fields:
run_id,endpoint_family,http_status,outcome,response_id_present,text_path_used,usage_present,error_type_present,redaction_checked,notes. - What not to assert: do not treat one smoke test as proof of model availability, billing behavior, long-term response shape, latency, uptime, or provider-specific parameter support.

Who this is for
This guide is for engineers adding persistence around CometAPI text generation calls, tutorial maintainers checking examples, and operators who need repeatable records for parser changes. It is especially useful when a project supports both chat-style and Responses-style text calls and needs storage fields that survive documentation updates.
It is not a model-selection guide, pricing guide, or reliability report. The storage choices here are intentionally modest: they help you keep enough evidence to debug your own parser and application behavior while avoiding claims that belong in separate model, billing, uptime, or provider-specific checks.
Key takeaways
- Store the endpoint family and parser path alongside the generated text so future maintainers know which response shape was used.
- Keep request payload summaries separate from raw prompts and credentials; use
<API_KEY_PLACEHOLDER>in examples and redact live values from logs. - Record success and error outcomes with the same local run id format so failed calls remain useful during troubleshooting.
- Treat model-specific behavior as something to verify in the linked docs before storing it as a stable application field.
- Keep citation links clean in evidence sections. If you need broader source hygiene before writing examples, use Review Sources Before Publishing CometAPI Code Samples .

Contract details to verify
| Area | What to verify | Source URL | Accessed | Safe candidate wording |
|---|---|---|---|---|
| Endpoint family | Whether a stored record came from chat completions or Responses. | https://apidoc.cometapi.com/api/text/chat | 2026-07-14 | Store an endpoint_family value such as chat only after matching the request to the official reference. |
| Response envelope | Whether the response includes an identifier, choices-style output, and usage fields for the tested call. | https://apidoc.cometapi.com/api/text/chat | 2026-07-14 | Store the response id and usage object when returned; do not require every optional field for every model. |
| Provider variation | Whether the chosen model family changes supported request parameters or response fields. | https://apidoc.cometapi.com/api/text/chat | 2026-07-14 | Store a parser note that says which documented shape was observed during the smoke test. |
| Responses path | Whether the text workflow should use the Responses reference instead of chat completions. | https://apidoc.cometapi.com/api/text/responses | 2026-07-14 | Store endpoint_family: responses only when the request is built against that official reference. |
| Support route | Where operators should look when a documented field or account behavior is unclear. | https://apidoc.cometapi.com/support/help-center | 2026-07-14 | Link operators to the current help page instead of writing unsupported support promises into logs. |
Failure modes
- Evidence gap: the team cannot inspect the failing log, source page, pull request, or local command output. The safe action is to stop and record the missing evidence instead of guessing.
- Scope drift: a repair changes files or fields that are not connected to the observed storage problem. Keep the repair tied to the saved result record and leave unrelated cleanup for a separate task.
- Environment mismatch: the local check uses different versions, credentials, feature flags, or runtime settings than the hosted path. Record the mismatch before treating the result as proof.
- Unreviewed fallback: someone changes models, endpoints, permissions, or retry behavior to make a run pass without preserving the review boundary. Treat access and provider failures as operational blockers, not schema failures.
- Weak handoff: the final note says the issue is fixed but omits the command, result, changed fields, and remaining uncertainty. That makes the next maintainer repeat the investigation.
- Overwide raw storage: the database keeps full prompts, full response bodies, or credentials because it is easier than choosing fields. Prefer a narrow, sanitized record unless your application has a documented retention requirement.
Reader next step
Before adding a new database column, run one happy-path request and one deliberately incomplete request in a non-production environment. Save both as sanitized records using the template above, then compare the stored fields against the current chat and Responses references. If a field cannot be tied to the official reference or to your own observed parser path, keep it in a temporary note instead of making it a required application field.
For a clean follow-up, open your storage migration and mark each proposed field as one of four types: local audit field, documented request field, documented response field, or observed parser note. Required columns should usually come from the local audit group. Optional columns can hold documented response fields when returned. Parser notes should explain how your code found the selected text without promising that every future model will return the same shape.

FAQ
Should I store only the final text?
No. Store the final text plus the local run id, endpoint family, response identifier when returned, parser path, outcome, and redaction status. That gives future maintainers enough context to debug parser changes without exposing secrets.
Should usage fields be required?
No. The chat reference shows usage fields in an example response, but a storage layer should record them when present rather than making unsupported assumptions for every model and endpoint family.
Can I store model identifiers as fixed enum values?
Only after verifying the current model source used by your application. This guide focuses on result storage fields, so model catalog claims should stay out of the schema until a separate model verification step supports them.
What should an error record keep?
Keep the local run id, endpoint family, HTTP status, sanitized error envelope, redaction check, and a short operator note. Do not store live API keys, full private prompts, or unredacted response bodies.
When should I update the fields?
Update the field list when your parser changes endpoint families, when the official references show a new response shape you plan to depend on, or when your own smoke tests show that an optional field is no longer safe to require.
