Verification PAYMENT-READYpayment-ready until 2026-09-20
Deterministic pre-execution safety gates and signed evidence for AI agents. The Action Safety pair scores consequential shell, Git, SQL, infrastructure, and deployment commands, returning risk, matched rule IDs, and an exact machine-readable escalation call: $0.01 for the quick preflight, $0.25 for the full workflow with a signed receipt and free verification. High and critical outcomes are needs_review and are never represented as human-approved. Also includes wallet, MCP-server, and email risk scoring, x402 payment-policy decisions, demand-provenance checks, and deterministic finance math (DCF/IRR, Black-Scholes greeks, PE distribution waterfalls). Every route is on Base mainnet, settles through the CDP Facilitator, needs no account or API key, and is priced at or below $0.25.
Pay from $0.01 to $0.25 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

VERDICT
ranking generation 3solid 80/100 #58 of 77 in Verification by measured score
What the score read on this service: status degraded, 100% uptime 30d, 437ms response p95, x402 compliance 14 of 14, $0.01 price against the category, on-chain traction measured. 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 Verification, 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 77 listings, this one among them. That set is wider than the 77 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.
ALTERNATIVES IN VERIFICATION
Other Verification 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).

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.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share is a concentration signal, not part of the ranking score.

] 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/hermes-plant/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.
