GET /v1/tributos/calendario

unprobed

Brazil's tax transition calendar, year by year from 2026 to 2033: which taxes are in force each year, at what rate, and when PIS/COFINS, IPI, ICMS and ISS are extinguished. The context an agent needs to know whether the tax rule it used is still valid on the date of the transaction. Free sample, no payment: https://api.brazilayer.com/v1/tributos/amostra

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

The catalog declares GET. 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.
