Questflow, an orchestration layer for the multi-agent economy, announced a strategic partnership with Polygon, a blockchain network that powers global payments and RWAs through its Layer-2 scaling solution. This partnership allowed Questflow to integrate its own x402 facilitator on Polygon, allowing AI agents on the blockchain to verifiably and securely transact on-chain.
The Questflow x402 Facilitator is now live on @0xPolygon, unlocking instant on-chain crypto payments for your APIs, agents, and services.

Why are x402 facilitators like Questflow important?
X402 is an open payment protocol designed to enable AI agents to autonomously perform digital transactions by linking payments to standard HTTP interactions. Instead of relying on traditional API keys or other conventional subscription models, x402 enables efficient payments through API access.
Multiple blockchains, including Polygon and many others, are increasingly integrating x402 payment processing directly into their chains to enable autonomous payment interactions between services, bots and agents.
However, many blockchains still lack EIP-3009 support, making such implementations rigid. By acting as a facilitator, Questflow addresses that complexity with a cross-chain facilitator infrastructure that supports EIP-3009, removes token and gas compatibility, and manages all relayer logic.
Through integration on Polygon, the Questflow x402 facilitator enhances this blockchain network with immutable receipts, on-chain settlements, and verifiable transactions. Questflow integration allows AI agents on the Polygon network to efficiently collaborate with millions of users and service providers across the ecosystem, making payments that are verifiable, transparent and fast in real-time.
Introducing x402: a new Web3 payments story
This integration positions Questflow as a key enabler of the x402 standard in the Polygon network, furthering its commitment to making autonomous AI use cases useful and verifiable. The x402 protocol is a new permissionless standard that integrates payment functions directly into the fabric of the Internet to support interconnected digital commerce. The new concept has revolutionized the traditional HTTP 402 “Payment Required” status code as a new method for AI agents, APIs, and websites to communicate and perform payment settlements in real-time.
