How this service works
Clean, normalized Brazilian public data (CNPJ, CEP, BCB rates, PTAX, holidays/business days, banks/ISPB) for AI agents. Paid endpoints use x402 (HTTP 402, USDC) — no signup or API key. Not affiliated with Receita Federal, Banco Central or Correios.
Output
Returns a JSON object with a count of matching banks and a results array, each entry containing the ISPB code, COMPE code, and short name of the matching bank(s). Example: {"count":1,"results":[{"ispb":"18236120","compe_code":"260","short_name":"NU PAGAMENTOS - IP"}]}
Example use cases
PIX transfer bank resolution
“I need to validate a PIX transfer — can you look up the ISPB code for Itaú in the Brazilian bank registry?”
Fintech onboarding bank verification
“Our onboarding form received 'Bradesco' as the bank name — can you find its COMPE code and ISPB from the Brazilian public bank list so we can store the canonical identifier?”
Bank name disambiguation for reconciliation
“I have a payment record with COMPE code 260 and I need to confirm which bank that corresponds to — can you search the Brazilian banks database for that code?”
Technical details
Endpoint
GEThttps://brasil-data-x402.wagner-proc.workers.dev/v1/banks/%7Bquery%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to resolve Brazilian bank identifiers (ISPB or COMPE codes) from a name or code fragment, especially in fintech workflows involving PIX transfers, TED/DOC payments, or bank account validation. Prefer this over scraping Banco Central's website or maintaining a local bank list, as it provides clean normalized data on demand with no API key required, only a small USDC micropayment via x402.
Side effects
- No matching bank found for query — returns count:0 with empty results array
- Invalid or unrecognized query string yields empty results
- Payment required (HTTP 402) if USDC x402 payment header is missing or malformed
- Network timeout on Cloudflare Worker edge node
- Rate limiting or quota exhaustion returning HTTP 429
