AgenticTrust
Signed did:web identity before an agent trusts a domain
AI agents call tools from domains they never checked. AgenticTrust is the open protocol, SDK, and CLI for signed did:web identity. Trustflow Systems hosts the registry at trustflow.systems. MIT on npm: @trustflow/sdk. Badge: Verified by AgenticTrust | trustflow.systems
Maker here.
AgenticTrust is the open protocol. Trustflow Systems is the registry we run for it.
A domain publishes https:///.well-known/did.json (W3C did:web) and a plain llms.txt. The DID proof is a compact JWS. The SDK accepts EdDSA (Ed25519) and ES256 (P-256) and rejects alg: none and HS*. Agents can call verifyDomain before they use a tool. LangChain and Vercel AI SDK middleware throw before they parse an unsigned llms.txt.
Install:
pnpm add @trustflow/sdk
npx trustflow init
Please do not npm install trustflow-sdk — that is a different, unrelated package.
Registration talks to https://api.trustflow.systems (POST /v1/register, then POST /v1/register/confirm). Public page: https://trustflow.systems/verify/. Badge text: Verified by AgenticTrust | trustflow.systems.
Code: https://github.com/etienne-sourc...
Happy to answer how a did:web proof is checked, or how to point verifyDomain at https://api.trustflow.systems.
