POST /v1/credits/1

method-gated

Buy $1.00 of Agent Toolbox credits for $1: returns an API key (shown once) that pays for every tool over HTTP and MCP with no per-call payment. Send an existing key in X-API-Key to top it up instead.

Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

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.
