// CHANGELOG

Entries, newest first.

Every API change lands here before it ships, per the versioning policy: /v1 only adds fields, /v0 may change with notice, and any version gets at least 90 days before retirement.

  1. Docs

    Authentication, errors and rate-limit guides

    Three guides join the reference: the two auth headers and scopes, every error code with its fix, and the per-plan limits with the headers to read.

    /docs/authentication/docs/errors/docs/rate-limits

    Latest
  2. Site

    Data group pages, comparisons, coverage and status

    One page per data group built around the real sample responses, two comparison pages, a coverage page and a point-in-time status page.

    /data/fluid-capacities/compare/status

  3. Site

    Privacy policy and terms of service published

    Version 1.0 of both documents, effective September 3, 2026, with the API versioning policy stated in the terms.

    /privacy/terms#versioning

  4. Changed

    Branded API origin

    Authenticated calls and the OpenAPI spec are served through the gateway on the site's own host. The spec's servers block now names that origin, so generated SDKs never learn the deployment URL.

    openapi.json

  5. Added

    Reference samples for every read endpoint

    The free sandbox and the quickstart console ship the same baked responses for the reference 2019 Honda CR-V EX, so every endpoint can be tried with no key.

    /quickstart
