payment-ready until 2026-09-03
Pay-per-call crypto market intelligence for AI agents on Base mainnet (x402 v2, USDC). Spot prices, trending coins, Fear & Greed index, gas prices, OHLC candles, DEX pair liquidity/volume, ERC-20 rug-pull/honeypot risk checks, and top DeFi yields — $0.002 to $0.02 per call.
Pay from $0.002 to $0.02 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.
VERDICT
ranking generation 3strong 97/100 #19 of 253 in Data by measured score
What the score read on this service: status online, 100% uptime 30d, 485ms 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 253 listings, this one among them. That set is wider than the 253 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.
ALTERNATIVES IN DATA
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).

] 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/cryptopulse-data-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.
Median across 9 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.
