Some errors include extra fields (e.g. `walletId` on 409 Conflict). Broadcast failures that occur after a persisted transaction row is created include `transactionId`, `failureStage`, and (on broadcast-stage failures) `failureCode`, and also set the `x-transaction-id` response header. If signing completed before the failure, `signedTransaction` is included so callers can inspect or retry the already-signed bytes. Common error codes: `INVALID_REQUEST`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `CONFLICT`, `WALLET_ALREADY_EXISTS`, `WALLET_ALREADY_CLAIMED`, `RATE_LIMITED`, `INTERNAL_ERROR`. responses: BadRequest: description: Invalid request body content: application/json: schema: $ref: '#/components/schemas/Error' example: code: INVALID_REQUEST message: type must be one of EVM, SOLANA, COSMOS, STELLAR Unauthorized: description: API key not provided content: application/json: schema: $ref: '#/components/schemas/Error' example: code: UNAUTHORIZED message: secret api key not provided Forbidden: description: Invalid API key content: application/json: schema: $ref: '#/components/schemas/Error' example: code: FORBIDDEN message: invalid secret api key NotFound: description: Wallet not found content: application/json: schema: $ref: '#/components/schemas/Error' example: code: NOT_FOUND message: wallet not found TooManyRequests: description: Rate limit exceeded headers: Retry-After: schema: type: integer description: Seconds until the rate limit window resets example: 60 content: application/json: schema: $ref: '#/components/schemas/Error' example: code: RATE_LIMITED message: Rate limit exceeded, try again shortly.
