x402 APIPassing, checked 2 h ago

Checks whether a token contract address is real, matches its claimed symbol, and whether its supply figures match an independent source (CoinGecko) — before trading, coding, or reporting against it. Catches hallucinated/wrong addresses, address-poisoning impersonation, and tokenomics hallucination.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://token-oracle.fly.dev/verify' \
  -H 'content-type: application/json' \
  --data-raw '{"address":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","chain":"base","expectedSymbol":"USDC"}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://token-oracle.fly.dev/verify' \

  --data-raw '{"address":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","chain":"base","expectedSymbol":"USDC"}' \
