# List headless agent runs

> List the credential-user's runs for this agent, newest first. Optionally
filter by `status` and cap the page with `limit`. Requires the
`agents:run` scope; only runs owned by the credential's user are returned.




## OpenAPI

````yaml https://api.nexspace365.com/api/openapi.json get /api/agents/{id}/runs
openapi: 3.0.3
info:
  title: NexSpace 365 API
  description: >
    Multi-industry enterprise workforce management platform — scheduling, HR,

    payroll, CRM, AI, and messaging suites.


    ## Authentication

    Three schemes: session cookie, JWT bearer, or API key (`nex_live_…` /

    `nex_test_…` / `nex_pat_…`). AI agents should use API keys with appropriate

    scopes.


    ## Authorization

    Endpoints require specific permissions via the RBAC system:

    - **Internal team**: Full platform access

    - **Facility users**: Scoped to their org/facilities

    - **Staff**: Limited to own data


    ## Error Contract

    All errors return `{ error: { message, code?, suggestion?, retryable? },
    requestId? }`.

    The `suggestion` field hints at how to fix the request; `retryable` signals
    whether

    retry-with-backoff is appropriate.


    ## Versioning

    Pin your integration to a specific API version via the `NexSpace-Version`
    header

    (date-based, e.g. `2026-05-10`). When absent, the latest version is assumed.

    Deprecated versions include `Sunset` and `Deprecation` headers. Discovery at

    `GET /.well-known/api-versions`.


    ## Idempotency

    Write operations (POST/PUT/PATCH) accept an `Idempotency-Key` header. If

    the same key + body combination is sent again within 24 hours, the original

    response is replayed. Different body with the same key returns 409 Conflict.


    ## MCP (Model Context Protocol)

    AI agents interact via `POST /mcp` using JSON-RPC 2.0. Call `tools/list` to

    discover available verbs, then `tools/call` to invoke them.

        API key or personal access token (NEX-1042). Send as

          - `nex_live_…`  — live API key (server-to-server)
          - `nex_test_…`  — sandbox API key
          - `nex_pat_…`   — personal access token (acts as the issuing user)

        Authorization is decided by the key's `scopes` array, not the
        owning user's RBAC role. See `POST /api/api-keys` to mint a key.
