paypi — Solana intelligence for AI agents

Blockchain PAYMENT-READY

payment-ready until 2026-08-20

Solana on-chain intelligence sold per call in USDC over x402. decode: turn any transaction (by signature or raw base64) into human-readable instructions, accounts and program names across 46 known mainnet programs. simulate: dry-run a transaction against live mainnet state before signing, returning compute units, logs and failure reasons via a paid RPC. kamino-liquidation: liquidation risk for any wallet on Kamino lending — LTV vs liquidation LTV, health buffer, per-asset liquidation prices and risk tier, using ported on-chain math rather than estimates. Charge-on-success: failed or refused calls are never charged. Free request/response examples at /samples.

Pay from $0.005 to $0.05 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

Evidence-backed signals, not a single score. Click any chip for the proof. Measured values stay read-only; unknown is honest.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance A (14/14)

14 of 14 x402 conformance checks pass. Full checklist below.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

OVER TIME

All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/paypi-solana-intelligence-for-ai-agents/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
