POST /execute/chain-state-snapshot-v1

unprobed

Current block number and gas price for Base and Polygon mainnet, fetched live via RPC on every call. Unlike this catalogue's corpus-search listings, this makes a real outbound network call on purchase -- freshness is the product, not a stored snapshot.

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://api.macaroonnetwork.com/execute/chain-state-snapshot-v1' -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.
