Address Labels

by address-labels in Onchain & crypto

x402 APIPassing, checked 4 h ago

Identify what an EVM address IS in one keyless call: contract/protocol identity (entity, name, category) from Open Labels Initiative attestations with trusted-attester consensus, plus on-chain truth (is_contract, code_hash), reverse ENS/Basename, sanctions (OFAC/UK/EU/UN) and scam-drainer flags. Cited provenance; unknown addresses answer with empty labels, never a 404.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://webtools402.176-109-107-191.sslip.io/address/labels?address=0x2626664c2603336E57B271c5C0b26F421741e481&network=base'

# 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 - 'https://webtools402.176-109-107-191.sslip.io/address/labels?address=0x2626664c2603336E57B271c5C0b26F421741e481&network=base' \
