GET /v1/base/gas

Base gas price, base fee and priority fee at head. Not an estimate of a specific call. Unread RPC is not zero.

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 GET 'https://ari001.tailb4ac3a.ts.net/v1/base/gas' -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.
