SPI error list

Error format The SPI API returns errors as RFC 9457 problem details with the application/problem+json media type:

{
  "type": "https://errors.lerian.studio/v1/SPI-1002",
  "title": "Unprocessable Entity",
  "status": 422,
  "detail": "bacen rejected payment",
  "code": "SPI-1002",
  "correlationId": "req-7a3f9c2e"
}

Field definitions

type – A URI that identifies the error in the Lerian error catalog, built as https://errors.lerian.studio/v1/<code>.
title – The HTTP status text (for example, Unprocessable Entity).
status – The HTTP status code.
detail – A human-readable explanation for this occurrence. The text varies with the occurrence, so branch on code.
code – A stable identifier for the condition. This API uses two vocabularies here: the rail’s own SPI-NNNN codes, and the Pix key directory tokens described further down.
errors – Optional list of per-field validation details, each with a message, a location, and the offending value.
correlationId – The request-scoped correlation identifier. Quote this value in a support request.

For 5xx responses, the rail replaces detail with internal error so internal causes stay inside. Use code to branch programmatically.

Rail codes

The SPI-NNNN codes name conditions the SPI rail itself judges. The digit after the prefix groups them: 0 input, 1 rail transport, 2 authorization, 3 processing, 4 rate and quota, 9 fallback. A code can carry more than one status when the condition it names has more than one shape on this rail. SPI-1002 means BACEN refused the message when the rail submitted it. A refused payment moves to REJECTED. BACEN can also refuse a payment later, in its status reply (pacs.002). That refusal is not an HTTP error, and the payment moves to REJECTED. To find which payments the network refused, read the rejected payments report. It lists each one by status and end-to-end id.

400: Bad request

`code`	Description	`detail`
SPI-0003	The request body is missing or cannot be parsed.	request body is required

401: Unauthenticated

`code`	Description	`detail`
SPI-2001	The request does not identify a principal. The bearer is missing, malformed, or unrecognized.	authenticated actor unavailable

403: Forbidden

`code`	Description	`detail`
SPI-2002	The caller is identified and is not authorized for this action.	forbidden

404: Not found

`code`	Description	`detail`
SPI-0010	The resource the request names does not exist.	payment not found

409: Conflict

`code`	Description	`detail`
SPI-0011	A resource with this identity already exists.	participant already exists
SPI-3006	The resource’s current lifecycle state refuses the operation.	payment is not eligible for return
SPI-3007	Another writer changed the resource between your read and your write. Re-read and retry.	participant status changed concurrently

413: Payload too large

`code`	Description	`detail`
SPI-0003	The request body exceeds the size limit. `HTTP_BODY_LIMIT_BYTES` sets the limit for most routes.	request body too large

422: Unprocessable

`code`	Description	`detail`
SPI-0001	A required input is missing or empty.	return reason is required
SPI-0002	A field carries the wrong format.	mode must be FULL or INCREMENTAL
SPI-0003	A business rule refused the request.	invalid payment request
SPI-0011	The charge surface refuses a duplicate identifier, such as a txid another charge already holds.	charge already exists
SPI-1002	BACEN rejected the message.	bacen rejected payment
SPI-1011	The Pix key directory rejected the request. Where the directory named the reason, the token arrives instead. See the directory tokens below.	bacen dict rejected request

429: Too many requests

`code`	Description	`detail`
SPI-4001	The rail’s BACEN-outbound quota is exhausted, or the Pix key directory throttled the request. A directory throttle carries the wait in the `Retry-After` header when the directory prescribed one.	bacen outbound quota exceeded

500: Server error

`code`	Description	`detail`
SPI-9000	An unexpected internal failure. Retry, then contact support with the `correlationId` value.	internal error

501: Not implemented

`code`	Description	`detail`
SPI-1012	The Pix key directory batch key check is not installed in this deployment. Do not retry.	internal error

502: Bad gateway

`code`	Description	`detail`
SPI-1005	Communication with BACEN failed for a reason the rail could not classify further.	internal error

503: Service unavailable

These codes name dependency conditions. Back off and retry.

`code`	Description	`detail`
SPI-1001	The BACEN transport is unavailable.	internal error
SPI-1004	Transport security validation failed. The rail refused to send on a channel it could not validate.	internal error
SPI-1010	The Pix key directory is unavailable, for maintenance or outside its service window.	internal error
SPI-3001	Persistence or event publication is unavailable.	internal error
SPI-9001	A downstream dependency the request needs is unavailable.	internal error

504: Gateway timeout

`code`	Description	`detail`
SPI-1003	BACEN did not answer within the rail’s window. The outcome is undetermined, so query the resource before you resend.	internal error

Pix key directory tokens

The Pix key directory keeps its own error vocabulary, and the rail forwards it. A directory refusal reaches you with the directory’s own token in code and the directory’s own HTTP status in status. The type URI carries the same token as its last segment. This vocabulary belongs to the directory, so treat it as open. Handle a token you do not recognize by its status, and read the token itself as the reason. The tables below list directory tokens for key registration, key lookup, key deletion, and the claim operations.

A rate-limit refusal from the directory reaches you as SPI-4001 with HTTP 429. When the directory prescribed a wait, the response carries it in Retry-After. See the rail codes above.

EntryKeyOwnedByDifferentPerson	A different person owns the key. Open a possession claim.	400
EntryKeyInCustodyOfDifferentParticipant	The same owner holds the key at another PSP. Open a portability claim.	400
EntryTaxIdNumberByDifferentOwner	The CPF or CNPJ on the entry differs from the key owner’s.	400

BR Code file rejections

The BR Code batch file channel answers a submitted remessa in a return file. A refused line carries a three-digit rejection code. It also carries the field name and description that the Pix scheme publishes for that code. A refused file carries one code, and no line in it is judged. Your reconciliation maps the answer against the scheme’s own error sheet. 063 (Cadastro, Cliente nao cadastrado) refuses the whole file: its header names a recebedor that this deployment does not hold a registered profile for. 096 (Registro, Inválido) says the scheme publishes no more specific code for the field at fault. A record of the wrong length is one of these. Four more cover the two identifiers that most lines carry. 012 (Chave pix, Chave inválida) says the line collects on a Pix key that this deployment does not hold a registered recebedor for. 014 (Chave pix, Não é compatível com o cnpj ou agência e conta informada) names a key registered to another recebedor. The file header resolves to a different one. 016 (Identificador (txid), Em duplicidade) says the txid repeats. 017 (Identificador (txid), Inválido ou não encontrado) says the txid is malformed or names a charge this rail does not hold. The scheme’s error sheet publishes many more codes. The channel renders the subset that its own refusals map onto. Each rejected line names its field, so read the field name first and the code second.
