Primary Facilitator

Solana x402 Payment Infrastructure

Surf Protocol (cascade.fyi)

Surf Protocol serves as the primary x402 facilitator on Solana, enabling micropayment settlement for AI agent API calls. Providers route Solana-based x402 payments through Surf's infrastructure, which handles USDC settlement on Solana mainnet.

Note: Many Solana x402 endpoints require payment headers (HTTP 402) to respond. Unreachable status often indicates endpoints behind payment gates or rate limiters — not necessarily dead services. Our scanner performs non-paying health checks to map the ecosystem.

Cross-Chain Comparison

BASE

Base (EIP-155:8453)

SOL

Solana (5eykt4UsFv8P)

144 endpoints 22 providers 0.66% of network

144

Why this matters: Solana x402 adoption is at an inflection point. With only 0.66% of the x402 network, there is massive growth potential. Base had a similar distribution 90 days ago before rapid adoption. Solana's low fees and high TPS make it ideal for x402 micropayment settlement.

Mapping Methodology

Discovery

Automated crawling of 402index registry, x402scan, .well-known/x402 manifests, and on-chain payment records to discover Solana endpoints.

Classification

Each endpoint is categorized by function (AI/Inference, Trading, Oracle, etc.) and tagged with provider, chain, and facilitator metadata.

Health Monitoring

Continuous health checks every 6 hours. HTTP status, response time, TLS validation, and payment header verification.

Attestation

Daily snapshot hash published on-chain (Base L2) for data integrity. Verifiable audit trail of the entire mapping dataset.
