Data PAYMENT-READY

payment-ready until 2026-09-06

Real-time crypto market data for AI agents: prices, perp funding rates and predictions, volatility, liquidation levels, correlation, on-chain vs CEX spreads, technical indicators, sentiment, plus differentiated institutional signals (trader positioning, spot ETF flows, macro/on-chain context, supply). NEW: /api/market-pulse bundles the eight most-polled signals into one call for $0.018 — 18% cheaper than the $0.022 the parts cost, and one settlement instead of eight, which matters when the facilitator pays the gas. Pay-per-request in USDC on Base via x402 - no account, no API key. Self-hosted facilitator. MCP endpoint and A2A agent card included.

Pay from $0.002 to $0.018 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT

ranking generation 3

strong 98/100 #13 of 252 in Data by measured score

What the score read on this service: status online, 100% uptime 30d, 422ms response p95, x402 compliance 14 of 14, $0.002 price against the category. Each of those is measured, and each is published in full below.

The score comes from our own monitoring, never from reviews, operator claims, or a language model: reliability, x402 compliance, price against the category, a deterministic risk flag, and a small on-chain traction term, weighted by ranking generation 3. It is not placement anyone can buy: the paid verify tier is reported beside it and is not one of its inputs. Every component below stays published and read-only.

It is a score inside Data, and only there: price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, which here means 252 listings, this one among them. That set is wider than the 252 the position above is counted against, because a listing we have measured too little of to rank still sits in the field the price and the speed are normalized over. The same service in a different field would read differently. The same engine answers GET /api/v1/best, and asked for a different pool (the whole directory, or another filter) it returns a different number for this service under this same ranking generation. Neither is more correct: they answer different questions, and the methodology states which is which.

Bands on the 0 to 100 measured score: strong at 93 and above, solid from 75, mixed from 55, weak below 55. Price and speed are scored against the whole category field, every listing in it that carries no danger flag, the scored service included, so the score places a service in its own field.

Other Data services in this directory, ordered by the same measured score. The figures are ours: 30-day uptime from our own probes, 30-day settlement volume read on-chain (a conservative undercount, and null where we cannot measure it, never a zero).

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.

OVER TIME

All charts use the 90d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/agentdata-api/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.
