Same tools, same price. Pick the path that fits your agent.
Prepaid balance
Top up once, create an API key, and every call draws from one balance. Best for teams and long-running agents. Works with the REST API and the MCP endpoint.
Get an API keyPay per call in USDC (x402)
No account and no key. The agent gets an HTTP 402, signs a USDC payment on Base, and the call settles only if the tool succeeds. Built for autonomous agents.
How x402 worksBrowse by category
Built a tool nobody is paying for yet?
Wrap it in one HTTPS endpoint, set a per-call price and list it. We route agent traffic to it, meter every call and handle billing. A skill is even simpler: paste your SKILL.md or import it from GitHub.
