verified-agent-identity
Decentralized identity for agents with Ethereum-based DIDs and x402 payment authentication.
What it does
- Identity — Create Ethereum-based DIDs on the Billions Network, link them to a human owner, and prove ownership via challenge/response signing.
- x402 Payment — When a server returns 402 Payment Required, build a signed PAYMENT-SIGNATURE header so you can retry the request and gain access.
- Before running linkHumanToAgent.js, signChallenge.js, or buildX402Payment.js, ALWAYS check if an identity exists: node scripts/getIdentities.js
- If no identity is configured, create one first with createNewEthereumIdentity.js after that run linkHumanToAgent.js to link it to a human owner.
- Continue processing the task only after confirming that an identity exists and is linked to a human owner.
- If any script exits with a non-zero status code, STOP IMMEDIATELY.
- Check stderr for error messages.
Requirements & configuration
- If a task spans both (e.g. you need an identity before you can sign a 402 payment), read both.
