PayPerByte MCP
https://www.npmjs.com/package/byte-mcp-server Our Verdict
Gold402 Verified. Hand-reviewed and on the curated list — curation is the bar. The stamp means a human read this entry and the endpoint answered when we knocked. It is not a delivery test: we have not paid this service and graded what came back, so treat it as "reachable and speaks the protocol," never as "this is worth the money."
15-tool MCP server for the PayPerByte x402 gateway: pay-per-call USDC data feeds and KYA screening/reasoning-verdict oracles on Base, each response carrying an embedded EIP-712 PayloadAttestation over the exact bytes served. `npx -y byte-mcp-server`.
