SDK method	Endpoint	Notes
`createDID(options?)`	`POST /api/v1/dids`	Auto-maps `keyType: 'ed25519'` → `Ed25519`

`deactivateDID(did)`	`DELETE /api/v1/dids/{did}`	Irreversible
`rotateKey(did, keyType?, currentKeyProof?)`	`POST /api/v1/dids/{did}/rotate-key`	`keyType` defaults `Ed25519`
`addDelegate(did, params)`	`POST /api/v1/dids/{did}/delegates`	ERC-1056 inspired
`listDelegates(did)`	`GET /api/v1/dids/{did}/delegates`
`revokeDelegate(did, params)`	`DELETE /api/v1/dids/{did}/delegates`	Body in DELETE
`setAttribute(did, params)`	`POST /api/v1/dids/{did}/attributes`

Example: create + resolve + rotate

import { IDAClient } from '@infinia/ida-sdk';
const client = new IDAClient({ apiUrl: 'https://adid.dev', apiKey: jwt });
// Create
const created = await client.createDID({
  keyType: 'ed25519',
  services: [{
    id: '#didcomm-1',
    type: 'DIDCommMessaging',
    serviceEndpoint: 'https://adid.dev/api/v1/didcomm/receive',
  }],
});
console.log('Created:', created.did);
// Resolve (chain-cached)
const doc = await client.resolveDID(created.did);
console.log('Doc:', JSON.stringify(doc, null, 2));
// Universal resolve (works for did:key, did:web, did:ethr too)
const { didDocument } = await client.resolveAny(created.did);
// Rotate key (proof must be a base64url signature over server-issued nonce)
await client.rotateKey(created.did, 'Ed25519', currentKeyProofBase64);

Example: delegate management

const delegate = await client.addDelegate(created.did, {
  delegateType: 'sigAuth',
  delegate: '0x90F8bf6A479f320ead074411a4B0e7944Ea8c9C1',
  validity: 86_400,  // 24 h in seconds
});
const list = await client.listDelegates(created.did);
await client.revokeDelegate(created.did, {
  delegateType: 'sigAuth',
  delegate: '0x90F8bf6A479f320ead074411a4B0e7944Ea8c9C1',
});
