Scores a caller-supplied DeFi yield, LP or staking position (protocol, pool address, APY, TVL, duration) and returns an execute/monitor/avoid verdict with risk flags plus an Ed25519-signed receipt. The pool address is checked on-chain for contract code; APY and TVL are caller-supplied, not fetched.
Pay from $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.

Identity facts, not a risk score.
traction ---
This service shares a payout address and its probe has been failing, so its on-chain volume is suppressed until it responds again. Settlements on a shared address while a member is down are not attributed to it.

] 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/synthora-defi-strategy-verdict/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.

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.
