payment-ready until 2026-08-20
Canonical token market data for a ticker: price, market cap, FDV, liquidity, 24h change and volume with buy/sell split and netflow, launch date, on-chain total supply (Nansen token-screener plus on-chain reads; response includes the required "Powered by Nansen API" attribution). Neutral facts only, no ratings, no predictions, not investment advice.
Pay from $0.10 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.
compliance A (13/14): x402 v2 envelope delivered in the payment-required header

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/sippar-token-market-data/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.
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.
