Evaluation pathway

  1. Define endpoints, fields, freshness, and expected request volume.
  2. Read the live source and confirm access, terms, limits, and version.
  3. Test representative inputs, errors, latency, pagination, and data quality.
  4. Plan monitoring, retries, caching, version pinning, and a fallback.

What still needs verification

Pricing and quotas

Confirm current plans, free-tier limits, overages, and request ceilings.

Endpoint coverage

Check that the operations and response fields match the intended workload.

Reliability

Look for uptime history, a status page, support routes, and service commitments.

Data and privacy

Review retention, licensing, regional processing, and compliance requirements.

Versioning

Confirm the active version, change policy, deprecation window, and migration guidance.

Developer experience

Validate SDKs, examples, error formats, pagination, and test environments.
