$0.002 per call · failed calls are never charged · no account needed: a card key or USDC

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://glyphcall.com/crypto/fear-greed?days=30"

Or one of your 3 free calls, no key:

curl "https://glyphcall.com/crypto/fear-greed?days=30&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.
