# Download artifact

> Downloads the artifact content. The signed URL (with expires and sig query params) is obtained from the artifact metadata endpoint.



## OpenAPI

````yaml /openapi/source/external/agent-browser/agent-browser.json get /artifact_downloads/{artifactId}
openapi: 3.1.0
info:
  version: 1.0.0
  title: Telnyx API
  x-latency-category: interactive
  x-endpoint-cost: light
  description: >-
    Isolated, short-lived browser sessions for AI agents — navigate, observe,
    click, fill, and screenshot through one API.


    ## Authentication


    All endpoints require a Telnyx API key sent as a Bearer token in the
    `Authorization` header.


    ## Session Quota


    Creating a session is subject to a concurrent-session quota per
    organization. When capacity is exhausted, create returns `429
    quota_exceeded` with `retryable: true`. Close unneeded active sessions or
    wait for capacity before retrying.


    ## Error Responses


    Request errors use `{ "error": { "code": string, "message": string,
    "retryable": boolean } }`. Execution failures are reported on action
    resources with HTTP 200 and `data.status` set to `failed` or `unknown`. A
    request can also return HTTP 503 `execution_lost`; inspect action and
    session state before retrying because the action may already have taken
    effect.
