Monad API Hub Brings Pay-Per-Request Access to APIs with USDC
The Monad API Hub has introduced pay-per-request access to APIs through micropayments, using Circle's USDC stablecoin. This system allows developers and autonomous AI agents to make requests without account creation or key management, paying a fee per request that ranges from $0.01 to $7.50.
The x402 v2 protocol is the core of this system, an open standard for internet-native payments that treats each API call as a tiny financial transaction. When a request is made, the facilitator on Monad handles verification and on-chain settlement automatically.
Nansen contributes 83 different endpoints to the hub, providing analytical depth. The hub has 66 active services from independent providers, with prices per endpoint visible rather than buried in enterprise tier structures.
The goal of the x402 Foundation is standardization: if multiple blockchains and service providers adopt the same protocol for pay-per-request transactions, developers can write integration code once and it will work everywhere. The Monad Foundation joined the x402 Foundation on June 29, 2026, alongside other contributors.
