How this service works
🆕 The 'who am I dealing with?' check for agents. Reads Coinbase's ONCHAIN verification (an EAS attestation by verifications.coinbase.eth) — meaning the address is tied to a KYC'd Coinbase account, the strongest sybil-resistance signal on Base — plus the address's Basename. Returns a verified/named/anonymous verdict + trust score. Pair with sign-guard/spend-audit for a full pre-transaction gate. Identity is a signal, not proof of honesty.
Output
Returns a verdict (verified, named, or anonymous), a numeric trust score, the address's Basename if one exists, and whether a Coinbase EAS KYC attestation is present — indicating the address is tied to a real, identity-checked Coinbase account.
Example use cases
Example prompt
“Before I send funds to 0x4a8f...d3c2, can you check whether that Base address is KYC-verified on Coinbase and give me a trust score — I want to know if it's verified, just named, or fully anonymous?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/address-trustWhen to prefer
Use this endpoint when you need the strongest available sybil-resistance signal on Base — specifically Coinbase's onchain KYC EAS attestation — before a transaction or interaction. Prefer this over generic on-chain activity checks when the question is 'is this a real, identity-verified human?' rather than just 'is this wallet active?' Pair with sign-guard and spend-audit for a full pre-transaction identity gate.
Side effects
- Invalid or malformed address returns an error
- Address not found on Base returns anonymous verdict with low trust score
- Network or RPC issues fetching EAS attestation data
- Rate limiting or payment failure on the x402 payment layer
