How we built parallelmpp.dev

Parallel has launched parallelmpp.dev, a gateway that enables autonomous agents to access Parallel's Search, Extract, and Task APIs using HTTP 402 Payment Required, allowing payments per request without the need for API keys or contracts. This system supports two payment rails, Tempo stablecoins and x402 on Base via Stripe, facilitating seamless transactions through a single middleware. The gateway's design leverages stateless 402 challenges, ensuring scalability and resilience, and employs Stripe's PaymentIntents for secure settlements. The platform offers both paid and free endpoints, with the POST /api/search, /api/extract, and /api/task being monetized while maintaining a consistent user experience regardless of the payment rail used. The protocol is self-describing, enabling agents to easily integrate and interact with the API, while the inclusion of a Claude skill enhances search accuracy and auditability. Future enhancements include per-agent budget headers and streamed 402 challenges for extensive task operations, with ongoing collaboration with the Machine Payments Protocol working group.
