POST /taxas-bcb

unprobed

Use for anything needing an up-to-date Brazilian benchmark rate: pricing a loan, indexing a contract, converting USD/BRL. No body required. Returns Selic (Copom policy rate), CDI (interbank rate) and USD/BRL (PTAX sell rate), each with its reference date, straight from the BCB's own SGS API.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://tools.miniframe.com.br/taxas-bcb' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
