GET /tax/brackets

unprobed

Reference tables for a US tax year and filing status: income brackets, standard deduction, FICA constants, and capital-gains breakpoints. Pure lookup, not tax advice.

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

curl -si -X GET 'https://api.agentstools.dev/tax/brackets' -H 'accept: application/json'

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.
