Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://glyphcall.com/polygon/gas?format=json"

Or one of your 3 free calls, no key:

curl "https://glyphcall.com/polygon/gas?format=json&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
