How do I get help with the Cartroute API?

Updated September 23, 2026 · API version 2026-09-01 · This page as JSON

Email [email protected] with the request_id from the response you are asking about. Live system status is at /status, API changes are in the changelog, and breaking changes only ship under a new dated API version.

What should I include in a support request?

• The request_id (in every response body and in the X-Request-Id header).
• The endpoint, the parameters and the time in UTC.
• The error code if there was one. Never send your API key.

How is the API versioned?

The current version is 2026-09-01, reported as api_version in every metered response. Adding fields, endpoints, error codes or enum values is not a breaking change, so clients should ignore unknown fields. Removing or renaming a field, or changing its meaning, ships under a new dated version announced at least 90 days ahead.

Where do I check whether something is down?

/status shows the API, MCP server, website and price pipeline, with last-hour request counts, latency and server errors. /status?format=json is suitable for monitoring.

How do I report a security issue?

Email [email protected]; see security.txt. Good-faith research that respects user privacy and service availability is welcome.
