How this service works
Create browser session; returns 402 when credits insufficient (x402 USDC on Base per docs)
Output
Returns a browser session object containing a session ID and connection details that the agent can use to issue subsequent browser commands (navigate, click, extract content, etc.). Returns HTTP 402 if USDC credits are insufficient.
Example use cases
Automate multi-step login flow
“Start a cloud browser session for me so I can log into my company's portal, navigate through the dashboard, and pull the latest monthly report — it needs JavaScript to render properly.”
Scrape dynamic product listings
“Spin up a browser session I can control so I can browse through an e-commerce site, scroll through dynamically loaded product listings, and extract pricing and availability data.”
Fill and submit web forms
“Open a remote browser session for me so I can go to the vendor registration page, fill out all the required fields, upload the necessary documents, and submit the form on my behalf.”
Technical details
Endpoint
POSThttps://api.anchorbrowser.io/v1/sessionsWhen to prefer
Choose this endpoint when you need a full, interactive cloud browser session where an AI agent must navigate pages, click elements, fill forms, or execute JavaScript — as opposed to simple HTTP fetching or static scraping. Best for dynamic web pages that require JavaScript rendering, multi-step interactions, or login flows.
Side effects
- 402 Payment Required — insufficient USDC credits on Base; agent must top up wallet before retrying
- 401 Unauthorized — missing or invalid API key
- 429 Rate Limited — too many session creation requests
- 503 Service Unavailable — browser infrastructure temporarily unavailable
- Session quota exceeded — account has reached maximum concurrent session limit
