payment-ready until 2026-10-11

Pay-per-answer NFL fantasy football analysis for AI agents and people. Ten x402-gated endpoints at $0.10–$0.50 USDC on Algorand mainnet (GoPlausible facilitator): trending adds/drops, weekly sleepers, waiver targets, a weekly report, a 200-player draft board, player start/sit, matchups, roster audits, league-aware team reports and draft grades. Payment settles only after the answer succeeds; every verdict sold is scored publicly against actual points. MCP server included; no API keys or signup.

Pay from $0.10 to $0.35 per request in USDC, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT

ranking generation 3

solid 82/100 #22 of 43 in Content by measured score

What the score read on this service: status online, 100% uptime, latest daily rollup (no 30d window yet), 191ms response p95, x402 compliance 11 of 13, $0.1 price against the category, no known payTo, so no on-chain traction to read. 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.

It is a score inside Content, 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 43 listings, this one among them. That set is wider than the 43 the position above is counted against, 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.

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.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.

compliance B (11/13): payTo is a valid on-chain address, network resolves to CAIP-2

11 of 13 x402 conformance checks pass; failing: payTo is a valid on-chain address, network resolves to CAIP-2. Full checklist below.

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.

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/play-clock/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.
