Errors

A failed call answers a Problem with a stable code, and every code below has a page of its own.

Codes

Code	Status	Cause
`invalid_key`	401	The Key the call presented is not one the platform accepts.
`key_required`	401	The Offer requires a Key, and the call presented none.
`bad_environment`	400	The call asked a test or dev Key to act on live records.
`not_entitled`	403	The Entitlement of the Key does not cover this operation.
`customer_unresolved`	503	The Customer behind the Key could not be resolved, so the call has nowhere to be kept.
`customer_unplaced`	503	The calls of the Customer have no namespace to live in.
`limit_exceeded`	403	The call is over a Limit, so it was refused before it ran.
`limits_unavailable`	503	The Limits could not be checked, so the call did not run.
`missing_param`	400	A required parameter is missing.
`invalid_param`	400	A parameter is not of its type, misses its pattern, or is not one of its values.
`not_found`	404	No record matches the input, so the call is a miss.
`invalid_batch`	400	The Batch body is not a list of 1 to 100 calls.
`no_route`	404	The path is not an operation of the API.
`method_not_allowed`	405	The API serves the path, but not with that HTTP method.
`invalid_call`	400	An MCP tool call named an unknown operation or sent input it cannot read.
`internal`	500	The operation failed inside the platform.
