Data PAYMENT-READY

payment-ready until 2026-08-20

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.

ASSESSMENT

updated 3h ago

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

reliability 100%

uptime 24h: 100%
uptime 7d: 100%
uptime 30d: 100%
uptime 90d: 100%
response p95: 242ms
avg response: 178ms
total checks: 2,737

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.

risk clean

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/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.
