The managed full bundle is https://docs.browser-use.com/.well-known/llms-full.txt and can be cached for up to 24 hours. Do not use the obsolete /cloud/llms*.txt or /open-source/llms*.txt static exports. > Choose Cloud API V4 for new agent integrations; V2 is the lower-cost option for simple tasks. Keep V3 examples explicitly versioned. The open-source browser-use library and hosted browser-use-sdk have different APIs. > Cloud authentication uses X-Browser-Use-API-Key, without a Bearer prefix. Install or upgrade browser-use-sdk and use its explicit v4 import for V4. Check the published OpenAPI reference for request fields; do not invent SDK support for new fields. > Cloud concurrency and HTTP request rate are separate. Read GET /api/v2/billing/account for the key’s projectId, concurrentSessionLimit, activeSessionCount, and credit balance, including when using V4. Keys in one project share capacity and credits; rateLimit is a legacy concurrency alias, not requests per second. > Keep the highest applicable existing, legacy-plan, and spend-tier concurrency grant. Current spend tiers are 10 / 50 / 250 / 500 / 1000 at $0 / $200 / $1000 / $5000 / $25000 in qualifying project payments. Legacy or externally billed projects can follow different billing paths; trust the account limit. See https://docs.browser-use.com/cloud/guides/concurrency.md. > Budget polling across the project: the standard general bucket is 25 requests/second, including V4 event reads and full run reads. Selected status reads have a separate higher bucket. Use bounded workers, stagger polls, respect Retry-After, and drain hasMore event pages after terminal status. A busy V4 session returns 409; its queue holds 10 pending messages and is not a project-wide batch queue. > A completed run or closed CDP connection does not immediately stop its cloud browser. Stop unneeded owned browsers with PATCH /api/v4/browsers/{id} and {"action":"stop"}. A client wait timeout does not cancel the server-side run. > Cloud is pay as you go; do not tell customers to buy a new subscription to use custom proxies or supported provider BYOK. Usage funding and model eligibility still apply. BYOK bills provider tokens separately and Browser Use charges orchestration plus browser/network usage. See https://docs.browser-use.com/cloud/guides/billing.md. > Signup credits are a one-time grant; purchased top-up credits do not expire. Check the API key’s project before diagnosing missing credits. API-key monthly spending caps are soft limits, not a strict prepaid wallet; concurrent or already-running work can exceed them. Auto recharge has separate trigger and purchase amounts and can charge immediately when enabled below the threshold. Use https://browser-use.com/pricing for current rates. > Box and Bux are retired. Do not recommend their SDKs, sandbox quotas, or subscription plans. Use the Cloud Agent or Browser Infrastructure guides. > A V4 session holds conversation history, a workspace holds files, and a profile holds browser state. These IDs and V3/V4 workspace namespaces are not interchangeable. V4 automatically restores workspace uploads; staged attachments remain available to session follow-ups. Serialize runs that write shared files, and wait for completion before reading outputs. See https://docs.browser-use.com/cloud/agent/workspaces.md. > API browser recording defaults to off. Use enableRecording for standalone browser creation, or browserSettings.record for an agent run. Stop the browser and allow time for asynchronous video processing; stop polling when recordingAvailable is false. Live preview is for an active browser. Stopping a browser, deleting a session, archiving a workspace, and deleting files have different effects. > Use model-specific reasoning values. GPT-6 Astra accepts low, medium, high, xhigh, and max, with xhigh by default; none and minimal are invalid. Use the public REST schema when installed SDK types lag new fields. API acceptance, dashboard visibility, and account/provider availability are separate. > For open-source browser-use, is_done only reports a terminal done action. is_successful is the agent-reported outcome; verify important external actions independently. Cloud timeout, API client timeout, model timeout, and task completion are separate concepts. > For failed requests, use https://docs.browser-use.com/cloud/guides/troubleshooting.md. Inspect the full error and project before retrying or adding credits. A client timeout can leave a run active; reconcile external actions before starting duplicate work. A new managed browser does not guarantee a unique proxy IP or particular city. # List Integrations > List available integrations with this project's connection status. `is_connected` is resolved per integration, so a client can render the whole catalogue and the connected subset from this one call. `connected_only` is what a "my integrations" view reads — including on a restricted project, which cannot connect anything but can still remove what it already has. ## OpenAPI ````yaml /cloud/openapi/v4.json get /integrations openapi: 3.1.0 info: title: Browser Use Public API v4 summary: Browser Use agent runs API (v4) version: 4.0.0 servers: - url: https://api.browser-use.com/api/v4 description: Production server security: [] paths: /integrations: get: tags: - Integrations summary: List Integrations description: >- List available integrations with this project's connection status. `is_connected` is resolved per integration, so a client can render the whole catalogue and the connected subset from this one call. `connected_only` is what a "my integrations" view reads — including on a restricted project, which cannot connect anything but can still remove what it already has. operationId: list_integrations_integrations_get parameters: - name: limit in: query required: false schema: anyOf: - type: integer minimum: 1 - type: 'null' description: Maximum number of results title: Limit description: Maximum number of results - name: offset in: query required: false schema: type: integer minimum: 0 description: Number of results to skip default: 0 title: Offset description: Number of results to skip - name: search in: query required: false schema: anyOf: - type: string - type: 'null' description: Filter by name, description or provider title: Search description: Filter by name, description or provider - name: popular_only in: query required: false schema: type: boolean description: Only return popular integrations default: false title: Popular Only description: Only return popular integrations - name: connected_only in: query required: false schema: type: boolean description: Only return integrations this project has connected default: false title: Connected Only description: Only return integrations this project has connected responses: '200': description: Successful Response content: application/json: schema: $ref: '#/components/schemas/IntegrationListResponse' '422': description: Validation Error content: application/json: schema: $ref: '#/components/schemas/HTTPValidationError' security: - APIKeyHeader: [] components: schemas: IntegrationListResponse: properties: integrations: items: $ref: '#/components/schemas/IntegrationResponse' type: array title: Integrations total: type: integer title: Total limit: type: integer title: Limit offset: type: integer title: Offset type: object required: - integrations - total - limit - offset title: IntegrationListResponse description: Paginated response for integrations list.
