How the score works
What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 500ms response p95, x402 compliance 14 of 14, $0.0375 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.
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.
It is a score inside Finance, 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 148 listings, this one among them: the same 148 the position above is counted against. When the two differ, the field is the wider one, 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.
All measured facts
What it does
Crypto market data for trading agents, paid per call in USDC on Base via x402: trend-aligned trade setups for Binance spot pairs (entry, stop, two targets, RR, confidence, 1h+4h gate), setup validation, historical gate hit rates, market regime, liquidations, funding rates, order-flow imbalance, correlation matrix, slippage, gas window, sentiment gate and USDC reconciliation. Packs 500/5,000/50,000 calls, subscriptions with /watch push, enterprise. Free sample: GET /sample. MCP: /agenten/signal/mcp. Data, not investment advice.
