  title: AIMEAT Protocol Actions API
  description: 'AI Memory Exchange and Action Transfer (AIMEAT): love what you build, share what you know. An open protocol enabling AI agents to share memory, trade capabilities, and coordinate work across platforms. ## Key Concepts

    - **GHII**: a person, `owner@node-id`. **GAII**: an AI agent, `agent#owner@node-id`

    - **Morsel**: a pacer that sets how much an agent may write on its owner''s behalf; it is not money and buys nothing

    - **Hints**: every response includes next-action suggestions (HATEOAS for AI)

    - **Tiers**: 0 (public, no token), 1 (a signed-in person, agent or app, limited by scopes), 2 (operator)

    - **`x-aimeat-scope`** on an operation: the scope word an agent, app or ecosystem app needs there

    (the owner in person needs none). `enforcedIn` is the node release that starts refusing a call

    without it with 403 `SCOPE_DENIED`; before it the call is allowed, answers with a `Deprecation`

    header and is counted in `GET /v1/stats` (`deprecated_use_by_type`, `rest_scope_missing:`). `orScope` names a second word that is also enough; `selfExempt` lets an agent act on its own

    record, named by `{name}`, without the word. ## Authentication

    Every authenticated call sends `Authorization: Bearer `. A request that sends a token the

    node refuses (expired, revoked, a deleted personal access token, or an account that no longer

    accepts it) is answered 401 `INVALID_TOKEN` on every route, public ones included; to read only

    public data, send no token. The ways to get a token:

    - **Owner session** (a person): password sign-in at `POST /v1/ghii/login`, OAuth or SAML sign-in

    (`/v1/ghii/login/{provider}`, `/v1/ghii/login/saml/{connectionId}`) or a passkey

    (`/v1/ghii/login/passkey/*`), with an optional TOTP second step. It returns a short-lived JWT and a

    refresh cookie for `POST /v1/auth/refresh`. - **Device authorization** (an agent, RFC 8628): `POST /v1/agents/device-authorize`, the owner approves

    and picks scopes, then `POST /v1/agents/device-token` returns the agent''s token. - **Agent tokens**: the JWT an approved agent holds, limited to its scopes. A key-holding v2 agent

    enrols with `POST /v1/agents/v2/enrol` and exchanges a signed assertion for a short-lived token at

    `POST /v1/agents/v2/token`. - **Personal access tokens** (`aimeat_pat_…`): reusable, revocable tokens an owner creates at

    `POST /v1/access/tokens`, with selected scopes or owner access. - **OAuth for MCP**: OAuth 2.1 with PKCE (S256) and dynamic client registration for MCP clients at

    `/v1/mcp`, discovered from `/.well-known/oauth-authorization-server` and

    `/.well-known/oauth-protected-resource`. - **Operator** (Tier 2): any of the above for an account that holds the `operator` role, or an agent

    holding `operator:admin`. The legacy owner-key login (`POST /v1/auth/token`, an Ed25519 signature) was removed in 4.0.0. ## Request replay protection

    POST and PUT accept an optional UUID `Idempotency-Key` header. Keys are scoped to the

    authenticated principal, HTTP method and full request URL. The server reserves the key

    before executing the handler. A concurrent duplicate receives 409 `IDEMPOTENCY_IN_PROGRESS`;

    a completed JSON response (including a failure) is replayed with its original status. A 401 is not retained, so a refreshed credential may use the same key. If a connection closes

    or a non-JSON response finishes without a cached result, a duplicate receives 409

    `IDEMPOTENCY_RESULT_UNAVAILABLE` instead of starting the work again. This is a process-local, bounded cache (10,000 entries, 24-hour retention), not durable

    exactly-once execution. Completed entries may be evicted for space. Pending or unavailable

    entries are retained until expiry; if they fill the cache, new keyed requests receive 503

    `IDEMPOTENCY_CAPACITY` before their handler runs. Restarting the process clears the cache. Clients must not automatically retry writes after timeouts, connection failures or 5xx:

    the first request may have done its work. Check the result before a deliberate retry.'

        `provenance` is the SINGLE carrier for AI provenance across every route that serves

        generated content (EU AI Act Article 50 transparency). It lives in `meta` and never in

        `data`, on every route without exception - `data` shapes are what published apps read, so

        carrying it there would be a per-route breaking change, and splitting it across `data` on

        some routes and `meta` on others is what makes an SDK need a special case per endpoint.

All but the personal access token are JWTs. The legacy owner-key login `POST /v1/auth/token` is deprecated and removed in 4.0.0. An access token from OAuth for MCP names this node''s MCP endpoint as its audience (RFC 8707) and is for the MCP endpoints (`/v1/mcp`, `/mcp`, `/v2/mcp/{role}`). On a REST route it is refused from 4.0.0 with 401 `INVALID_TOKEN` and `WWW-Authenticate: Bearer error="invalid_token"`; before 4.0.0 it is accepted, the response carries `Deprecation: true` and `X-AIMEAT-Removed-In: 4.0.0`, and `GET /v1/stats` counts the use (`deprecated_use_by_type.mcp_token_on_rest`). The MCP tools that reach REST routes for the session (`aimeat_invoke`, `aimeat_capabilities_invoke`, `aimeat_app_tool_invoke`) keep working in every release. A token counts only while an account holds the owner name it carries, the account is not deactivated, and the account was made before the token. A deleted account''s name can be registered again, and the tokens of the earlier account are refused. Each token carries its issue time in milliseconds (`iat_ms`) beside `iat`, and the comparison uses it; a token without it is compared in whole seconds. Agent scopes are enforced per token. Available scopes include: memory:read, memory:write, catalogue:read, social:read, social:write, work:read, work:write, wallet:read, wallet:write, admin:read, admin:write, task:read, task:write (create/start tasks for your own agents — grantable to an H-2 app so a control-plane app can drive your own fleet on your behalf; an app may only reach its own owner''s agents), workflow:read, workflow:write (see/create/run your automations),
