How the score works

What the score read on this service: status offline, 53.1% uptime 30d, 730ms response p95, x402 compliance 13 of 13, $0.00175 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 Data, 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 477 listings, this one among them: the same 477 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

Real-time aviation data including flight tracking, airport information, aircraft types, and aviation weather. Pay-per-request via x402 micropayments.

Aviation x402 is a listed x402 Data API. Captured payment terms name Arbitrum One, Avalanche, Base, Polygon. Monitoring and settlement figures below describe the observations available to this directory; an unpaid HTTP 402 check does not prove that a paid call will deliver.

Assessment computed at 2026-11-08 23:33:29 UTC. Latest service check observed at 2026-11-08 21:05:05 UTC. Service data JSON · Measurement methodology.

Page rendered at 2026-11-09 02:34:09 UTC. This response time is separate from the observation and computation times attached to each measurement.

Latest endpoint observation: 2026-10-11 12:38:04 UTC. Latest price capture: 2026-10-08 23:18:10 UTC. Prices are recorded quotes, not a promise of availability. Token assets and payment terms are listed separately. Endpoint data JSON · Price history JSON · Measurement methodology.

Assessment computed at 2026-11-08 23:33:29 UTC. Uptime uses the stated daily-rollup window; response times are in milliseconds, compliance is passed/evaluated checks, and traction is a measured settlement floor. The comparison score is out of 100 within this category. Assessment JSON · Measurement methodology.

Observed daily coverage: 2026-10-10 to 2026-11-08 UTC. Daily monitoring and settlement rollups do not expose their computation time; a bucket date is not an update timestamp. Uptime and response JSON · Volume JSON · Buyers JSON · Measurement methodology.

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.

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.
