# Self Agent ID

The SDK exposes Self Agent ID via `celina.self` — the same flows as [celina-mcp](https://www.npmjs.com/package/@andrewkimjoseph/celina-mcp) tools (`verify_self_agent`, `register_self_agent`, etc.).

For browser-first apps, also consider the official [`@selfxyz/agent-sdk`](https://www.npmjs.com/package/@selfxyz/agent-sdk).

## Configuration

```ts
import { createCelinaClient } from "@andrewkimjoseph/celina-sdk";

const celina = createCelinaClient({
  selfAgentPrivateKey: process.env.SELF_AGENT_PRIVATE_KEY as `0x${string}`,
  selfApiBase: "https://app.ai.self.xyz", // optional
});
```

| Option / env                                     | Purpose                                |
| ------------------------------------------------ | -------------------------------------- |
| `selfAgentPrivateKey` / `SELF_AGENT_PRIVATE_KEY` | Signing, identity, refresh, deregister |
| `selfApiBase` / `SELF_AGENT_API_BASE`            | Override ai.self.xyz REST base URL     |

Read-only verification (`verifyAgent`, `lookupAgent`, `verifyRequest`) does not require a key.

## Read examples

```ts
// On-chain verification by agent address (defaults: age 18+, OFAC required)
await celina.self.verifyAgent({
  agentAddress: "0xC1C860804EFdA544fe79194d1a37e60b846CEdeb",
});

// Relax gates explicitly if needed
await celina.self.verifyAgent({
  agentAddress: "0xC1C860804EFdA544fe79194d1a37e60b846CEdeb",
  requireAge: 0,
  requireOfac: false,
});

// Lookup by numeric agent ID (REST + on-chain expiry)
await celina.self.lookupAgent(1);
```

Verified agents expose credentials including `nationality` (ISO 3166-1 alpha-3, when disclosed at registration), `older_than`, `ofac_clear`, and `ofac_checks` — a labeled array derived from Self’s on-chain `bool[3]` OFAC field. Each check has `list`, `label`, and `clear` (`clear: true` means **not on that sanctions list**). **`ofac_clear` is true only when every check has `clear: true`** (full screening passed at registration). `lookup_self_agent`, `verify_self_agent`, and `get_self_identity` return this normalized shape — not a raw `ofac` array.

## Registration flow

```ts
// Defaults: minimumAge 18, nationality disclosure, OFAC screening
const session = await celina.self.registerAgent({
  mode: "wallet-free",
  agentName: "my-agent",
});
// session.session_id, session.qr_code_url, session.deep_link — present BOTH links to the human

const status = await celina.self.checkRegistration(session.session_id);
// When complete: status.private_key_hex — set SELF_AGENT_PRIVATE_KEY locally
```

Registration disclosures default to `{ minimumAge: 18, nationality: true, ofac: true }` so Self agents are not tied to under-18 or OFAC-listed humans, and nationality is available on later verify/identity reads. Opt out with `minimumAge: 0`, `nationality: false`, or `ofac: false`.

Sessions are stored **in-process** for \~10 minutes. They are lost on server restart and do not work across stateless serverless instances (same as hosted MCP).

A newly registered agent address holds no CELO. On `celina-mcp`, fund it from your main wallet and switch humanness-gated writes to it once `SELF_AGENT_PRIVATE_KEY` is set — see [Two wallets: CELO + Self agent](/celina-sdk/guides/mcp-session-wallet.md#two-wallets-celo--self-agent) in the MCP session wallet guide.

## Signed HTTP (agent key required)

```ts
const { headers } = await celina.self.signRequest({
  method: "POST",
  url: "https://app.ai.self.xyz/api/demo/verify?network=celo-mainnet",
  body: JSON.stringify({ ping: true }),
});

await celina.self.authenticatedFetch({
  method: "POST",
  url: "https://app.ai.self.xyz/api/demo/verify?network=celo-mainnet",
  body: JSON.stringify({ ping: true }),
});
```

Use `?network=celo-mainnet` (not `mainnet`) for Self demo/gated APIs on Celo.

## Proof refresh and deregister

* `refreshProof()` — only after on-chain proof expiry (`isProofFresh` false)
* `deregisterAgent()` — irreversible; returns QR/deep link session like registration

Poll completion with `checkRegistration(session_id)` for refresh and deregister sessions too.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://andrewkimjoseph.gitbook.io/celina-sdk/guides/self-agent-id.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
