## Errors

- `invalid_argument` (400): A required field is missing, a field is unknown, or a value does not match its type (the Convex validator's path and value are in the message).
- `invalid_request` (400): A writer refused a value: a map link on a host that is not allowed, a title that is too long, a date that does not exist, too many items in a list. The message is the writer's own sentence.
- `unauthenticated` (401): The request carries no key. Send it as Authorization: Bearer sk_sceniq_... (or X-Api-Key).
- `invalid_api_key` (401): The key is unknown, revoked or expired.
- `api_scope_required` (403): A read-only key called a write operation, or a key without the publish option called publish_changes.
- `forbidden` (403): The key belongs to a creator account that is no longer active.
- `not_found` (404): The id does not exist or belongs to another creator. The two answers are identical on purpose, so ids never reveal what exists.
- `payload_too_large` (413): A JSON body over 2 MB, an image over 6 MB, a batch upload over 19 MB, or an MCP message over 2 MB.
- `rate_limited` (429): Over a limit: requests per key per minute, per creator per hour, uploads per key per minute, or check_links per guide per hour.
- `internal_error` (500): An unexpected failure. The message is hidden on purpose.
