Verify CometAPI Base URLs Before Publishing Tutorial Examples

Last reviewed: 2026-06-25.

Direct answer

Before publishing a CometAPI tutorial example, verify three things in order: the client is configured with the documented CometAPI base URL, the sample uses the endpoint family the tutorial promises to teach, and the local smoke test records only stable facts that are supported by the current public documentation. The CometAPI documentation shows OpenAI SDK examples configured with base_url="https://api.cometapi.com/v1". The chat completions reference documents POST /v1/chat/completions for multi-message chat requests, while the Responses reference has its own page and should be checked separately when the tutorial is written for that endpoint family.

A practical verification workflow starts with setup assumptions. The reviewer should have a CometAPI key stored outside the tutorial text, a short throwaway test prompt, a selected endpoint family from the current docs, and a local client configuration that can be changed without editing the published article. Public examples should use <API_KEY_PLACEHOLDER> wherever a credential would appear. The tutorial should never print a real key, paste a real authorization header, or include screenshots that reveal credentials.

The happy-path request plan is intentionally narrow. Configure the client with the documented base URL, choose either Chat Completions or Responses, send the smallest request that exercises the tutorial path, and confirm that the result reaches the expected endpoint family. For a Chat Completions example, the check can record that the tutorial points readers to the chat completions reference and uses the documented base URL pattern. For a Responses example, the check should point to the Responses reference instead of copying assumptions from the chat page.

The error-path check should be just as narrow. Run one local request with an invalid placeholder credential, malformed local input, or another deliberately controlled failure. The purpose is not to reverse-engineer every error response. It is to confirm that the sample client fails without leaking secrets and that the tutorial does not claim behavior it has not verified. If the observed failure is ambiguous, write down the source page and the local condition, then avoid turning that single run into a general rule.

Minimum assertions should stay close to the contract: request start time, documentation URL, configured base URL, endpoint family, HTTP status class, whether a response object was returned, and whether the client preserved the configured base URL. Do not assert pricing, rate limits, uptime, latency targets, model availability, provider-specific parameter support, or billing behavior from a base URL smoke test. Those topics require their own source pages and their own review.

Who this is for

This guide is for tutorial authors, SDK maintainers, and integration reviewers who need CometAPI examples to stay accurate as documentation and model support evolve. It is especially useful when a tutorial adapts an OpenAI-compatible client, when a sample changes from Chat Completions to Responses, or when a reviewer needs to approve a code block without expanding it into unsupported claims.

It is not a replacement for production validation. A base URL check answers a smaller question: does the tutorial point the client at the CometAPI API host and does the example match the endpoint family it names? Production readiness may involve model selection, retry behavior, observability, cost controls, and application-specific error handling. Keep those decisions separate so a small tutorial smoke test does not become evidence for unrelated operational promises.

Key takeaways

• Verify the base URL from the current CometAPI documentation before copying setup code into a tutorial.
• Keep endpoint-family checks separate because Chat Completions and Responses are documented on different reference pages.
• Use <API_KEY_PLACEHOLDER> in public examples and keep real keys out of article text, logs, and screenshots.
• Log only stable smoke-test facts, such as documentation URL, endpoint family, status class, and whether a response object was returned.
• Link readers to the exact source page that supports each contract detail instead of generalizing across endpoint families.
• Treat a failed or inconclusive smoke test as a reason to narrow the claim, not as permission to guess.

A sanitized log record can look like this:

run_id: "base-url-check-YYYYMMDD-001"
docs_url: "https://apidoc.cometapi.com/api/text/chat"
client_base_url: "https://api.cometapi.com/v1"
endpoint_family: "chat-completions"
status_class: "2xx-or-non-2xx-placeholder"
response_object_returned: "yes-or-no"
result: "pass-or-fail"
notes: "No credentials, prompts, full responses, prices, limits, uptime, or model availability recorded."

Contract details to verify

This table should be filled before the article text is finalized. If the docs page supports only the base URL and endpoint path, keep the tutorial claim to that scope. If a code sample also discusses streaming, structured output, error handling, rate limits, or model selection, attach the specific source that supports each added detail.

Failure modes

• The tutorial copies a base URL from an old snippet instead of checking the current documentation. Fix this by re-opening the docs entry point and endpoint reference before publication.
• The article mixes endpoint families, such as describing Chat Completions while linking to Responses. Fix this by choosing one primary endpoint family and using the other only for comparison.
• The sample records too much local evidence, including prompts, full responses, or credentials. Fix this by replacing sensitive details with a compact status-class log.
• The reviewer treats one successful request as proof of cost, rate-limit, uptime, or model-availability behavior. Fix this by removing those claims unless the tutorial cites a source dedicated to that topic.
• The code block uses a real or realistic-looking key. Fix this by replacing the credential with <API_KEY_PLACEHOLDER> and moving any actual key handling to local environment setup outside the article.
• The base URL check passes, but the selected model, parameters, or response parsing logic is unsupported for the endpoint family. Fix this by reducing the tutorial claim to base URL verification or by adding the exact source page for the extra behavior.

Reader next step

Open the current CometAPI documentation, confirm the base URL shown there, and then compare the endpoint family in your tutorial against the matching reference page. If your example uses Chat Completions, review Validate CometAPI Chat Completions for Production after the base URL check so you can keep wiring checks separate from production validation. If your example might use Responses, review Choose between CometAPI Chat Completions and Responses before you publish the code sample.

Use the sanitized log template above as the publication note for the tutorial. A pass means the article names the correct documentation URL, uses the documented base URL, matches the intended endpoint family, and avoids unsupported operational claims. A fail means the example should be held until the source page, endpoint family, or local client configuration is corrected.

Use CometAPI Base URL and Endpoint Family Review as the next comparison point. Keep How to Smoke-test the CometAPI Chat Completion Contract nearby for setup and permission checks.

FAQ

Should a tutorial hard-code the CometAPI base URL?

A tutorial can show the documented base URL, but the review step should still re-check the current docs before publication. Put credentials in environment variables or local secret storage, and use <API_KEY_PLACEHOLDER> in public examples.

Is one successful request enough to prove the tutorial is production-ready?

No. A smoke test can confirm that the example is wired to the expected base URL and endpoint family, but it should not be used to claim pricing, rate limits, uptime, latency, or model availability.

When should I compare Chat Completions and Responses?

Compare them when the tutorial could plausibly use either endpoint family. Link to both reference pages, then state only the differences supported by those pages. If the tutorial is only about a Chat Completions client, do not add Responses behavior unless the comparison helps the reader choose the right endpoint.

What should be recorded after the test?

Record the documentation URL, base URL, endpoint family, status class, whether a response object was returned, result, and short notes. Do not record real keys, full prompts, full responses, prices, limits, uptime, or model availability claims.

What should I do if the docs and local example disagree?

Pause the tutorial update, identify the exact difference, and reduce the public claim to what the current source supports. If the example cannot be corrected with the available source pages, leave the unsupported behavior out of the article.
