CometAPI Gateway Evidence Workflow for Tutorial Authors

Last reviewed: 2026-06-24

Direct answer

A CometAPI gateway evidence workflow is the proof file a tutorial author creates before publishing a code example. It should show which CometAPI documentation page supports the endpoint family, which request shape the example depends on, which response family the reader should expect, where model choices should be checked, and where a reader should go if a documented request still fails.

The useful unit is not a broad checklist. It is one evidence row per tutorial example. If a draft has one Chat Completions snippet and one Responses snippet, create two rows. Each row should name the source URL, the endpoint family, the example file or section being checked, the placeholder credential location, the smallest request fixture the tutorial needs, the response fields the article mentions, and the claims the author removed because the sources do not prove them.

Use this operator workflow before writing or updating the public tutorial:

1. Setup assumptions: the author has access to a CometAPI account, a non-production client, and a credential stored outside the article. Any credential shown in notes or examples must be written as <API_KEY_PLACEHOLDER>.
2. Happy-path request plan: choose either the Chat Completions reference or the Responses reference, copy only the documented endpoint family and request concepts needed by the tutorial, run a minimal request in a test environment, and record status class plus response shape. Keep the public article focused on the documented source, not on raw execution logs.
3. Error-path check: run one deliberately invalid request, such as a missing placeholder credential or an incomplete required input, and confirm the client captures a failure without printing secrets, prompts, or a full response body.
4. Minimum assertions: source URL checked, endpoint family used, request fixture name, required tutorial fields present, expected response object family observed, secret redaction confirmed, and unsupported claims removed.
5. Pass/fail logging fields: checked_at, source_url, tutorial_section, endpoint_family, request_fixture, status_class, response_shape_observed, secret_redacted, claims_removed, result, and notes.
6. What not to assert: do not use this workflow to promise pricing, billing behavior, rate limits, model availability, latency, uptime, or long-term reliability.

For endpoint-family context, compare this workflow with Review CometAPI Base URLs and Endpoint Families . For a narrower local evidence pattern, use Local Smoke Test Evidence for CometAPI Tutorial Authors as the companion article.

Start with CometAPI when you are ready to compare your own tutorial notes against the current CometAPI documentation.

Who this is for

This guide is for tutorial authors, maintainers, and integration reviewers who write CometAPI gateway examples for readers. The immediate job is to turn a draft snippet into a small evidence record before the article makes claims about endpoint behavior, request fields, response shape, model choice, or support next steps.

It is also for teams that maintain several CometAPI tutorials at once. A tutorial can become hard to trust when the prose names one endpoint family, the code sample resembles another endpoint family, and the support note points to a generic help path. The evidence workflow keeps those decisions separate. The author checks the Chat Completions page for chat-style examples, the Responses page for response-style text generation examples, the models overview when a model choice is part of the tutorial, and the help center when the article tells readers how to get assistance.

Use Build Source-Checked CometAPI Integration Tutorials when the whole article needs source discipline. Use Choose between CometAPI Chat Completions and Responses when the draft is still deciding which endpoint family belongs in the example.

Key takeaways

• Build one evidence row for each tutorial snippet, not one vague approval note for the whole article.
• Keep Chat Completions and Responses evidence separate because they are documented on separate CometAPI pages.
• Use the models overview as a place to verify model-catalog guidance before naming or changing model choices in tutorial code.
• Treat the help center as support-path evidence, not as proof of endpoint behavior.
• Record sanitized status and shape observations only. Do not publish credentials, full prompts, raw responses, or account-specific output.
• Separate source-backed claims from local observations. A documentation page can support wording about an endpoint family; a local check can only support that one tested fixture behaved in a specific way.
• Remove claims that are not supported by the source set, especially pricing, billing, quotas, uptime, latency, or broad availability statements.

A compact evidence row can look like this:

checked_at: "2026-06-24T00:00:00Z"
source_url: "https://apidoc.cometapi.com/api/text/chat"
tutorial_section: "chat example setup"
endpoint_family: "text chat"
request_fixture: "minimal_placeholder_request"
status_class: "2xx_or_expected_4xx"
response_shape_observed: "top_level_shape_checked"
secret_redacted: true
claims_removed: "pricing, uptime, model availability"
result: "pass_or_fail"
notes: "short note without credentials, prompts, or full response body"

The row is intentionally small. It gives the next author enough context to repeat the check without copying private material into the article.

Sources checked

• CometAPI chat completions reference - accessed 2026-06-24; purpose: verify chat completion contract areas.
• CometAPI documentation - accessed 2026-06-24; purpose: verify current CometAPI documentation navigation.
• CometAPI help center - accessed 2026-06-24; purpose: verify support and escalation documentation areas.
• CometAPI responses reference - accessed 2026-06-24; purpose: verify responses endpoint contract areas.
• CometAPI models overview - accessed 2026-06-24; purpose: verify model catalog discovery guidance.

Contract details to verify

Do not stretch this table into broad product claims. It supports careful tutorial wording. It does not prove pricing, billing, account limits, performance, provider availability, or future model support.

Failure modes

• Mixed endpoint evidence: the article describes Chat Completions in prose but the code sample or response discussion belongs to Responses. Fix this by splitting the evidence row and choosing one source for each snippet.
• Missing source anchor: the author says a field, role, status, or response shape is required but cannot point to the source page used for that statement. Remove the claim or add the correct source before publishing.
• Unsanitized local output: a copied request log includes a real credential, prompt text, account detail, or full response body. Replace credentials with <API_KEY_PLACEHOLDER> and reduce observations to status class, shape, and field presence.
• Overclaiming from a successful request: one test request can support a narrow fixture note, not a promise about reliability, quota, billing, latency, pricing, or model availability.
• Model drift: an older tutorial names a model or model family without rechecking the models overview. Treat the model note as stale until the source is checked again.
• Support shortcut: the article invents troubleshooting advice when the documented request still fails. Point readers to the help center and preserve uncertainty instead of creating an unsupported workaround.
• Evidence row without article cleanup: the source check is complete, but the public article still contains claims the row does not support. The final pass should compare every endpoint, request, response, model, and support sentence against the evidence row.

Reader next step

Pick one CometAPI gateway example from your draft and create a single evidence row before editing the article. Start with the endpoint family. If the example is a chat-style conversation, use the Chat Completions reference. If the example is response-style text generation, use the Responses reference. If the example names a model or tells readers how to choose one, add a model-catalog check. If the example tells readers what to do when a documented request still fails, cite the help center.

After the row exists, make a claim-by-claim pass through the tutorial. Keep statements that are supported by the source URL or by a sanitized local observation. Remove statements about pricing, account limits, billing, rate limits, latency, uptime, or availability unless a current source in the article directly supports that wording. The finished tutorial should leave readers with a practical example and a clear path back to the documentation, not a set of promises the evidence row cannot prove.

FAQ

Should every CometAPI tutorial example get its own evidence row?

Yes. One row per example keeps endpoint-family, request, response, model, and support evidence easy to review. A tutorial that compares Chat Completions and Responses should have separate rows for each source.

Can I publish a model name from an older tutorial?

Do not rely on the older tutorial by itself. Check the current models overview before naming or changing model choices, and avoid availability promises unless the current source directly supports them.

What should the article say about credentials?

Use placeholders only. Public examples and evidence notes should show <API_KEY_PLACEHOLDER> instead of real credentials or example-looking keys.

Does a successful smoke test prove the gateway is production-ready?

No. It can show that one documented fixture behaved as expected in one controlled check. It does not prove uptime, latency, quota, billing, pricing, or long-term reliability.

What should I do when the documented request still fails?

Record the source URL, request fixture, status class, and sanitized error observation. Then use the CometAPI help center as the support path instead of inventing behavior that the checked sources do not prove.
