Direct answer
Before publishing any CometAPI tutorial, authors should verify three categories of source evidence: (1) endpoint reachability and contract areas from the official chat completions and Responses endpoint documentation, (2) model catalog awareness from the models overview, and (3) a passing smoke-test log record that confirms the happy path worked and the error path was exercised. Exact field names, endpoint paths, request shapes, and response structures must be verified against linked official sources at the time of writing—they can change between doc snapshots.
The official documentation entry point is https://apidoc.cometapi.com/. Before drafting tutorial code, load both the chat completions reference and the Responses endpoint reference, then confirm any model identifiers appear in the current models overview. If sources are unreachable or contradict your draft, pause and note the discrepancy rather than publishing stale examples.

Who this is for
This guide is for CometAPI tutorial authors, developer advocates, and technical writers who draft integration examples, code snippets, or walkthroughs using the CometAPI chat completions or Responses endpoints. It is also useful for editors who review tutorials before publication and want a structured way to assess whether source evidence is current and sufficient.
You do not need deep API expertise. You do need access to the official CometAPI documentation and a way to record a smoke-test log (a simple text file or structured JSON log is sufficient).
Key takeaways
- Always load the current official endpoint documentation before writing or updating tutorial code examples—do not rely on memory or cached screenshots.
- Verify request field names, response shape, and endpoint path directly from source; these details are the parts of a tutorial most likely to drift.
- Check the models overview before hardcoding any model identifier in a tutorial snippet; model identifiers that appear in older articles may no longer be listed.
- Run a minimal two-request smoke test (one happy path, one error path) and record a sanitized log before marking a tutorial ready for publication.
- Do not assert pricing, rate limits, billing details, or uptime targets in tutorial copy unless an approved current source directly supports that exact claim.
- Link to the official help center for support and escalation paths rather than paraphrasing support terms.
Smoke-test workflow
Setup assumptions
- You have a CometAPI account and a valid API key set in your environment (for example, as COMETAPI_KEY). Do not hardcode credentials.
- You are testing the chat completions endpoint. The current documented endpoint path should be verified in the chat completions reference before using it.
- You have confirmed the model identifier you plan to use appears in the current models overview.
Happy-path request plan
Send a minimal well-formed request using the fields documented in the current chat completions reference. A minimal request typically includes the model identifier, a messages array with at least one user turn, and any required authentication header. Verify the exact required fields in the official reference before writing your tutorial—do not copy field names from older examples without checking.
Assert:
- HTTP response status is 2xx.
- The response body includes a non-empty content field (or equivalent field as documented) in the first choice.
- Response latency is recorded in the log (as an observation, not a guaranteed threshold).
Error-path check
Send a request that should be rejected—for example, an empty messages array or a deliberately malformed payload. Assert:
- The response status is 4xx.
- The response body includes an error object or message. Verify the documented error shape in the official reference.
Minimum assertions
- Happy path returns 2xx and a non-empty response content field.
- Error path returns 4xx and a structured error body.
- No 5xx responses on either path during initial smoke test.
Pass/fail logging fields (see log template below)
What the smoke test must NOT assert
- Specific pricing, billing amounts, or token cost estimates.
- Uptime percentages or latency SLA guarantees.
- Model availability beyond what is visible in the current models overview.
- Rate limit ceilings unless a current approved source documents the exact limit for your account tier.
Sanitized log record template
Record these fields after each smoke test run. Use placeholder values; never log real API keys, full prompts that contain sensitive data, or complete response bodies from production systems.
smoke_test_log: date: “YYYY-MM-DD” endpoint_ref_url: “https://apidoc.cometapi.com/api/text/chat" # URL you verified before testing model_ref_url: “https://apidoc.cometapi.com/overview/models" # URL you verified model ID from model_id_used: “” # Replace with current docs value happy_path: http_status: 200 response_content_field_present: true latency_ms: 0 # Replace with observed value pass: true error_path: http_status: 400 error_body_present: true pass: true overall_pass: true notes: "” # Any discrepancy between draft and docs observed here tester: “”
Failure modes
- Evidence gap: the agent 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: the agent edits files that are not connected to the observed failure. Keep the repair tied to the failing signal 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: the agent 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 topic failures.
- Weak handoff: the final note says the issue is fixed but omits the command, result, changed files, and remaining uncertainty. That makes the next operator repeat the investigation.

FAQ
Q: Can I reuse model identifiers from an older CometAPI tutorial I wrote six months ago? A: Not without checking. Model identifiers can be added, renamed, or deprecated. Before using any model ID in a tutorial, verify it appears in the current models overview.
Q: Do I need to run a smoke test if I am only making minor edits to an existing tutorial? A: If your edit touches any code example, endpoint path, field name, or model identifier, run at minimum a quick happy-path check and record the result in a log entry. Minor copy edits that do not affect code do not require a new smoke test, but note your reasoning.
Q: What should I do if my smoke test returns a 5xx response? A: Record the status code and timestamp in your log, wait a short interval, and retry at least once. If the problem persists, do not publish the tutorial with that code example. Check the help center for service status information and open a support query if needed.
Q: Should I include pricing information in my tutorial? A: Only include pricing information if a current, approved source directly supports the exact claim at the time of writing. Pricing can change; stale pricing claims create reader trust problems. If you want to mention pricing, link to the official pricing page and describe it as “subject to change” rather than asserting specific figures.
Q: My tutorial covers both chat completions and the Responses endpoint. Do I need to check both references? A: Yes. Both endpoints have separate documentation pages with distinct request and response contracts. Verify each independently even if the overall workflow is similar. See the Responses endpoint reference and the chat completions reference.
Q: Where can I get help if I find a discrepancy between the documentation and actual API behavior? A: Use the CometAPI help center to open a support query. Document the discrepancy clearly, including the documentation URL, the behavior you expected, and what you observed.
