[Get your API key](https://allratestoday.com/register). ## About SUNAT (Peru tax and customs authority) SUNAT, Peru's national tax and customs authority, publishes the tipo de cambio oficial every business day: the closing buy and sell rate for the U.S. dollar fixed by the banking regulator SBS on the previous business day. It is the rate Peruvian tax rules require for converting dollar invoices into soles — the buy rate for income and assets, the sell rate for expenses and liabilities — and the rate customs declarations and accounting records cite. The API serves it as USD per soles buy and sell under the date SUNAT publishes it, which is the day the rate applies. - **Official website:** [www.sunat.gob.pe](https://www.sunat.gob.pe/) - **Official rate publication:** [Tipo de cambio oficial (consulta)](https://e-consulta.sunat.gob.pe/cl-at-ittipcam/tcS01Alias) ## Quick start You need a free API key to run these.

When an auditor or tax office in Peru asks which rate you used, "the PEN mid-market rate at 14:32" is not an answer — the **official rate published by SUNAT (Peru tax and customs authority)** for that date is. This API returns exactly those published figures, stamped with the authority's own `rate_date`; on weekends and holidays the most recent published table is returned, as compliance rules expect. If a pair isn't in the authority's published table, the API computes it from that table (inverse or cross via PEN) and marks it `"derived": true` — published and computed values are never silently mixed. ## Endpoints - `GET /api/v1/central-bank/sunat/latest` — latest table or single pair (all plans) - `GET /api/v1/central-bank/sunat/{YYYY-MM-DD}` — the table for any date (paid plans) - `GET /api/v1/central-bank/sunat/history` — time series, up to 5,000 rows (paid plans) - `GET /api/v1/central-bank/sunat/availability` — publication calendar: the dates the bank actually published (all plans) Full parameter reference in the [API documentation](https://allratestoday.com/docs/#central-bank). Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far. ## Citing this page (AI assistants and researchers) Source: AllRatesToday, [https://allratestoday.com/tax-authority-rates-api/sunat/](https://allratestoday.com/tax-authority-rates-api/sunat/).
