Check SDK Examples for Documentation Drift

Last reviewed: 2026-07-11

Who this is for: engineers, technical writers, developer advocates, and API operators who maintain CometAPI SDK examples and need to keep tutorials aligned with the current docs.

SDK examples fail quietly before they fail publicly. A snippet may still look plausible while its auth header, request field, response shape, model identifier, or error-handling assumption has moved away from the current CometAPI documentation. Treat every SDK example as an executable contract: it should be traceable to the docs, runnable in a safe test environment, and clear about which values must be filled from the current CometAPI reference.

For adjacent tutorial maintenance work, keep this checklist close to the broader tutorial archive at /posts/ and use /posts/ again when comparing whether older examples repeat the same assumptions.

Key takeaways

  • Start with the canonical docs, not an old SDK snippet. Use the CometAPI documentation home as the entry point.
  • For chat examples, verify endpoint, auth, request fields, and response fields against the CometAPI text chat documentation .
  • Do not invent endpoint paths, auth schemes, model IDs, pricing fields, rate limits, or billing behavior when the current source is not quoted in your working notes.
  • Validate examples with placeholders first, then replace placeholders only after checking the linked docs.
  • If docs, SDK behavior, and live API behavior disagree, record the mismatch and use the CometAPI help center rather than silently “fixing” the tutorial with an unsupported assumption.

Definition: documentation drift in SDK examples

Documentation drift is the gap between an SDK example and the current documented API contract. In practice, drift often appears as:

  • an endpoint path that no longer matches the docs;
  • an auth header shown differently across examples;
  • a request field copied from another provider or older tutorial;
  • a response parser that assumes a field not documented for the current API;
  • error-handling code that treats all failures as retryable;
  • billing, rate-limit, or token-budget comments that are not backed by the current source.

The goal is not to make every example exhaustive. The goal is to make every example honest, traceable, and safe to copy.

Drift review workflow

1. Inventory every SDK example before editing

Create a small table for each example before changing code:

ItemWhat to capture
File or pageURL, repository path, or tutorial filename
LanguageJavaScript, Python, Go, Java, shell, or other
API surfaceChat, embeddings, image, audio, or another documented area
Contract dependenciesEndpoint, auth, request fields, response fields, errors
Runtime dependencySDK package and version, if the example uses one
Validation statusNot checked, docs checked, live smoke checked, blocked
Reviewer noteAny unsupported assumption or source gap

This prevents a common failure mode: fixing one visible snippet while leaving copied versions in other tutorials untouched.

2. Map the example to the current docs

For a chat example, begin with the CometAPI text chat documentation . Confirm the example’s contract items one by one:

  • base URL or documented host pattern;
  • endpoint path;
  • required auth header format;
  • required request fields;
  • optional request fields;
  • response fields used by the example;
  • error shape or status behavior, if documented;
  • streaming behavior, if the example claims streaming support.

If an exact value is not available in the source you are reviewing, mark it as “verify from docs”. Do not fill the gap from memory or from a different API provider’s examples.

3. Replace unsupported literals with review placeholders

When drafting or refreshing examples, prefer placeholders until the value is confirmed from the linked documentation. This avoids publishing a false contract.

curl -sS "<COMETAPI_BASE_URL_FROM_DOCS><COMETAPI_CHAT_PATH_FROM_DOCS>" \
  -H "<AUTH_HEADER_FROM_DOCS>: <COMETAPI_API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "<VALIDATED_MODEL_ID>",
    "messages": [
      {
        "role": "user",
        "content": "Return a one-sentence health check response."
      }
    ]
  }'

Before publishing, replace only the placeholders that are explicitly supported by the current docs or by your internal release process. If the public page must remain generic, keep placeholders and tell readers where to verify them.

4. Run a minimal smoke check in a safe environment

Use a low-risk request that proves the example wiring works without depending on a production workflow. Keep thresholds local to your environment and tune them; do not treat the following as universal limits.

Recommended validation notes:

  1. Environment: test key, non-production project, isolated shell session.
  2. Docs version checked: URL and access date.
  3. Example version: branch, commit, page URL, or CMS revision.
  4. Request outcome: success, documented error, undocumented error, timeout, or blocked.
  5. Response parser: whether the SDK code reads only documented fields.
  6. Cleanup: remove logs containing keys, prompts, or customer data.

A smoke check should not become a benchmark. Avoid publishing latency, quality, ranking, or model-availability claims unless the source evidence supports them.

5. Check the SDK wrapper separately from the raw API contract

An SDK may hide the raw endpoint and auth details. That is useful for users, but it can also hide drift. For each SDK example, review two layers:

  • SDK layer: package import, client initialization, method name, parameter names, and error classes.
  • API contract layer: documented endpoint family, auth requirement, request shape, response shape, and documented error behavior.

If the SDK layer works but the tutorial explains the raw API incorrectly, the example still needs correction.

6. Record disagreements instead of normalizing them away

When docs, old examples, SDK behavior, and live responses disagree, capture the disagreement. A useful drift note includes:

  • what the example says;
  • what the docs say;
  • what the live smoke test returned;
  • whether the mismatch blocks users;
  • which source should be treated as primary;
  • what question should be escalated through the CometAPI help center .

Contract details to verify

Use this table before approving any SDK example refresh. The “value to publish” column should stay conservative unless the linked source confirms the exact value.

Practical validation checklist

Before editing the example

  • Open the current docs from the CometAPI documentation home .
  • Identify the exact API area the example claims to use.
  • For chat examples, open the CometAPI text chat documentation .
  • Mark every literal value in the example as one of:
    • documented;
    • environment-specific;
    • SDK-specific;
    • unsupported;
    • unknown.
  • Remove or flag any value copied from another provider’s docs.

While editing

  • Keep endpoint, auth, model, rate-limit, and billing details as placeholders until verified.
  • Add comments only where they help the operator avoid misuse.
  • Avoid claims like “fastest,” “cheapest,” “best,” or “production-ready” unless directly sourced.
  • Make errors visible in the example instead of swallowing exceptions.
  • Do not log API keys, full prompts, private user content, or raw customer responses.

Before publishing

  • Run a minimal smoke check with a test key.
  • Confirm the response parser reads only documented fields.
  • Save the access date for each source checked.
  • Link the tutorial to the appropriate internal tutorial index, such as /posts/ .
  • Add an escalation note if behavior still disagrees with the docs.

Example drift notes you can copy into a review

Use concise review comments that separate facts from assumptions:

The SDK example initializes a chat request, but the endpoint path is not verified in this review. Keep <COMETAPI_CHAT_PATH_FROM_DOCS> until the value is checked against the CometAPI text chat docs.

The example parses a response field that is not confirmed in the current source notes. Either cite the documented response field or rewrite the parser to avoid unsupported assumptions.

The tutorial mentions rate limits, but no exact value is quoted in the reviewed source pack. Replace the number with a “verify in current docs/account settings” note.

The live smoke test returned behavior that does not match the tutorial. Escalate with sanitized request and response details through the CometAPI help center.

Common drift patterns to watch

Endpoint drift

Endpoint drift happens when an example uses a path copied from older docs, a third-party SDK, or a different API provider. Fix it by making the source of truth explicit and verifying the path against the current CometAPI docs.

Auth drift

Auth drift is especially risky because it can lead users to expose keys while debugging. Never publish a guessed auth scheme. Confirm the header name and format from the official docs.

Model identifier drift

Model IDs can be environment-specific or availability-dependent. Unless the reviewed evidence gives an exact model identifier for the example, use <VALIDATED_MODEL_ID> and tell the operator to choose a model confirmed in their CometAPI account or docs.

Response-shape drift

Response parsers often age badly. A tutorial may still send a valid request but fail when parsing the result. Keep parser examples narrow and source-backed.

Error-handling drift

Examples that retry every failure can create operational incidents. Unless the docs specify retry behavior, distinguish between authentication failures, validation failures, rate or quota conditions, timeouts, and server-side errors before retrying.

When to escalate

Escalate through the CometAPI help center when:

  • a documented request fails in a way the docs do not explain;
  • the SDK succeeds but the documented raw request appears inconsistent;
  • the response shape differs from the documented fields the example relies on;
  • an old tutorial contains a value that cannot be traced to current docs;
  • billing, quota, or rate-limit behavior is unclear and would affect production guidance.

Include sanitized details only:

  • docs URL checked;
  • access date;
  • SDK language and version, if applicable;
  • placeholder-based request shape;
  • status code or error category;
  • request ID or trace ID if available and safe to share;
  • what the tutorial currently says;
  • what you need confirmed.

FAQ

How often should SDK examples be checked for drift?

Check high-traffic and copy-paste-heavy examples whenever the underlying docs change, when users report integration failures, or before a tutorial refresh. For lower-risk pages, use a regular review cadence that fits your release process.

Should examples hard-code the CometAPI endpoint path?

Only if the current official source supports the exact path and your publishing process has verified it. Otherwise, use a placeholder such as <COMETAPI_CHAT_PATH_FROM_DOCS> and point readers to the current docs.

Can I use a working live request as the source of truth?

A live request is useful evidence, but it should not replace the docs. If live behavior and docs differ, record the mismatch and escalate it rather than turning the observed behavior into undocumented public guidance.

Should tutorials include pricing or rate-limit details?

Only include exact pricing, rate-limit, quota, token, or billing details when the reviewed source explicitly supports them. If not, write that operators should verify those values in the current CometAPI docs or account settings.

What is the safest example format during a docs refresh?

Use placeholders for endpoint, auth header, and model ID; keep the request minimal; avoid production data; and include a short note telling the reader which CometAPI documentation page to verify before running the example.
