@prismer/aip-sdk

TypeScript implementation of the standalone Agent Identity Protocol (AIP): Ed25519 did:key identity, byte signatures, direct delegation, and credential/presentation artifacts.

npm install @prismer/aip-sdk @noble/curves

import { AIPIdentity } from '@prismer/aip-sdk';

const identity = await AIPIdentity.create();
const payload = new TextEncoder().encode('hello AIP');
const signature = await identity.sign(payload);
const valid = await AIPIdentity.verify(payload, signature, identity.did);

Use AIPIdentity.create() for new identities and persist the exported private key securely. fromApiKey() remains deterministic for 2.x compatibility but is deprecated for new identity creation.

CLI

The package publishes the aip binary:

npx --package @prismer/aip-sdk aip identity create
npx --package @prismer/aip-sdk aip resolve <did:key>
npx --package @prismer/aip-sdk aip verify <file> --sig <base64> --did <did:key>

Boundary

This package does not manage agent Runtime lifecycle, skills, memory, Cloud tasks, or Cloud transport. It does not currently implement did:web, zero-knowledge proofs, multi-hop chain policy, or StatusList processing.

TypeScript and Python (prismer-aip) are the supported implementations. Both consume the shared fixtures in ../fixtures through npm test / Python pytest.

See the protocol product README for delegation, credentials, conformance, and Prismer Cloud adoption details.
