payment-ready until 2026-08-20
Composable crypto/DeFi data for agents: gas, Hyperliquid funding+OI, DeFi yields, prices, Polymarket odds in one paid call, plus deterministic derived facts (liquidation price, net funding cost, net APY). x402 v2 exact on Base, settles via PayAI facilitator.
Pay from $0.01 to $0.02 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

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.

Attributed pro-quota: this payout address is shared, so volume is the operator-level figure divided by the services sharing it, while buyer and transaction counts stay whole. A declared convention, not an individually observed measure, and still a conservative undercount.
Currently sharing this payout address with agentmail, chainkit, difftool, jsonguard, x402 Agent-Commerce Starter + Platform Map.
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/chainfeed/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.
Median across 5 endpoints. Use the selector to isolate one.
checklist grew 11->14 on 2026-07-28; a step here is a metric change, not a regression
Measured site and economics pillars from the assessment history, so the latest value shown elsewhere on this page reads as a point on a trend rather than a permanent state.
Shared payout address (5 other services). These bars are the full shared address (operator-level), so do not sum them across the services that share it. Where a per-service figure is attributed, the assessment block and the ranking, it is the address total divided pro-quota by the 6 services sharing it: a declared convention, not an individually observed measure.
