Blockchain PAYMENT-READY

payment-ready until 2026-09-12

Machine-payable Solana transaction intelligence for autonomous agents: live priority-fee quantiles, transaction simulation, confirmed-transaction diagnostics, and token mint risk analysis. Every response is deterministic structured JSON, paid per call in mainnet USDC over x402 v2, with no account or API key.

Pay from $0.002 to $0.008 per request in USDC on Solana, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT

ranking generation 3

solid 83/100 #26 of 41 in Blockchain by measured score

What the score read on this service: status offline, 99% uptime 30d, 477ms response p95, x402 compliance 13 of 13, $0.002 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.

It is a score inside Blockchain, 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 41 listings, this one among them. That set is wider than the 41 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.

Other Blockchain services in this directory, ordered by the same measured score. The figures are ours: 30-day uptime from our own probes, 30-day settlement volume read on-chain (a conservative undercount, and null where we cannot measure it, never a zero).

ASSESSMENT

updated 1h ago

The parts the verdict above is computed from, each with its proof. Click any chip. Measured values stay read-only; unknown is honest, and an unknown is never counted as a zero.

reliability 99%

uptime 24h: 0%
uptime 7d: 93.5%
uptime 30d: 99%
uptime 90d: 99.3%
response p95: 477ms
avg response: 215ms
total checks: 2,485

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

compliance A (13/13)

13 of 13 x402 conformance checks pass. Full checklist below.

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.

This service settles on a network x402-list does not measure yet, so on-chain volume is not counted here. Shown as unmeasured, not zero.

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/utilia-solana-preflight/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.

VOLUME (on-chain settlement, USD)

This service settles on a network x402-list does not measure yet, so on-chain volume is not counted here. Shown as unmeasured, not zero.

This service settles on a network x402-list does not measure yet, so distinct on-chain buyers are not counted here. Shown as unmeasured, not zero.
