payment-ready until 2026-08-20
Derived crypto trend data for autonomous agents — not a price feed. PP-SuperTrend trend state across ~1,600 crypto assets: bull/bear direction on 1D, 4H and 1W, how many bars ago each asset flipped, the band level at which the trend invalidates, RSI divergences and 14-day momentum. These are computed signals over years of history from a continuously running pipeline, so an agent cannot cheaply reproduce them. Pay per call in USDC on Base from $0.01 — no signup, no API key, no subscription.
Pay from $0.01 to $0.05 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

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.

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

] OVER TIME
All charts use the 24h selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/trend-signals/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 4 endpoints. Use the selector to isolate one.

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.
