Endpoints and prices
| Method | Path | Description | Price | Network | Asset | 402 channel | Captured |
|---|---|---|---|---|---|---|---|
| POST | / | AI agent action safety: one-cent deterministic preflight for every consequential agent command. Returns risk, matched rule ids, and an exact machine-readable escalation call: full DestructGuard evidence for medium risk or the complete Action Safety workflow for high and critical risk. | $0.01 | Base | USDC | header | since 07-30 |
| POST | / | Complete AI agent action safety workflow for consequential agent actions. Runs the complete DestructGuard evidence score, conditionally creates ReviewQueue triage for high or critical risk, returns an honest allow or needs_review decision, a signed receipt, and a free 30-day status record. Human approval itself requires a connected approval system or hosted Assurance plan. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Signed receipt for one agent action. Post an x402 payment intent or MCP tool call (optional policy + settlement outcome) and get a canonical HMAC-signed record: binding hash, verdict, findings, and a free public verify URL third parties can check without trusting your agent's logs. Loop it after every payment or tool call to build a tamper-evident audit trail. Canonicalization hermes-stable-json-v1; org history and probes available on Assurance plans. | $0.05 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic fixed-income & loan analytics. Bond mode: solve price<->yield-to-maturity, current yield, Macaulay & modified duration, and convexity from the bond's terms. Loan mode (send principal + annualRate + termMonths): level-payment amortization with monthly payment, total interest/paid, and the full schedule. Pure math from caller-supplied terms · no market-data feed, no fabrication. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic cash flow analysis and return analytics in one call: NPV, IRR (periodic), XIRR (dated), MOIC / DPI / TVPI, payback period, plus an optional DCF valuation (enterprise value, equity value, implied share price) with Gordon-growth or exit-multiple terminal value. Pure math from caller-provided cashflows · no market-data feed, no fabrication. Every metric is accompanied by evidence-backed findings and a signed response receipt. | $0.20 | Base | USDC | header | since 07-30 |
| POST | / | Premium deal underwriting in one deterministic call: a DCF valuation (enterprise value, equity value, implied share price; Gordon-growth or exit-multiple terminal), equity returns (IRR/XIRR, NPV, MOIC, payback), a discount-rate × terminal-assumption sensitivity grid, and the LP/GP distribution waterfall on the proceeds. Pure math from caller-provided inputs · no market-data feed, no fabrication · with evidence-backed findings on every section and a signed response receipt. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic risk scorer for autonomous-agent commands. Scores a shell, SQL, or git action for destructive, deployment, and data-mutation risk before execution and returns a risk level, the matched policy rules, and an approve-or-block recommendation. Pure rules, evidence per match, no fabrication. | $0.10 | Base | USDC | header | since 07-30 |
| POST | / | Email validation API for AI agents. Validates one email per call: RFC 5322 syntax, disposable and temporary domain detection, role-based address, free-provider classification, typo suggestion (gnail.com -> gmail.com), plus-alias normalization to canonical form, and a deliverability score with per-rule evidence. Deterministic - the same record always gets the same answer - no data feed, no network calls. Loop it over your contact list to validate, dedupe, and normalize every record. Signed response receipt included. | $0.02 | Base | USDC | header | since 07-30 |
| POST | / | Verify an agent-commerce evidence bundle before trusting a paid result. Checks x402 challenge, receipt, policy-decision, and service-response artifacts; endpoint, method, network, payTo, and price binding; artifact source, freshness, hashes, and synthetic-proof leakage. Returns verified / needs_review / rejected / insufficient_evidence with per-rule evidence. Deterministic · loop it over every paid call in an agent run. | $0.05 | Base | USDC | header | since 07-30 |
| POST | / | CashflowLens return and DCF analytics plus PortfolioGuard concentration and risk scoring in one paid call, with structured internal evidence and a tamper-evident signed receipt. Pure math from caller-provided cashflows, holdings, and returns; no market-data feed and no claim that inputs are independently verified. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Analyze an MCP server manifest for security risk before install · destructive actions, over-broad scopes, sensitive-data egress, weak auth, prompt-injection surface, and permission diff. Returns per-tool, per-factor findings with severity, why, and a concrete fix (not just a score). | $0.05 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic Black-Scholes-Merton European option pricing and Greeks. Returns price, d1/d2, full Greeks (delta, gamma, vega, theta, rho) in canonical and conventional display units (vega per 1%, theta per day, rho per 1%), plus intrinsic value, time value, and moneyness. Supports continuous dividend yield. Pure math from caller-supplied parameters · no market-data feed, no fabrication. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Preflight an x402 payment before an autonomous agent signs it. Checks resource binding, method, scheme, network, asset, amount vs expected price, payTo, facilitator, timeout, replay and idempotency readiness, metadata leakage, buyer spend limits, allow-lists, and optional service-risk signals. Returns allow / deny / needs_review with evidence-backed findings and a redacted, log-safe record. Deterministic policy engine · loop it over every payment your agent makes. | $0.05 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic portfolio risk analysis and quality scoring. Computes riskScore, riskLevel, volatility, sharpe, maxDrawdown, concentrationHHI, diversification, effectiveHoldings plus per-rule findings with fixes and sector/position breakdown. Pure math only from caller holdings and returns. No external data. | $0.15 | Base | USDC | header | since 07-30 |
| POST | / | Submit an autonomous-agent command for paid risk triage and human-approval routing. Returns a deterministic risk decision, a request id, whether a human is required, and a recommended action · pause-and-escalate on critical risk. Evidence-backed, nothing fabricated. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | One signed preflight combining caller-supplied wallet risk signals, Payment Policy challenge validation, and internal evidence binding. Unknown wallet risk requires review, not permission to pay. No external chain-intelligence or sanctions lookup, independent screening clearance, or settlement verification is supplied. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Wallet risk scoring of caller-supplied signals only: sanctions hits, exposure tags, labels, transfers, and funding context. Positive findings receive a 0-100 score; absent risk findings return riskLevel unknown and riskScore null, requiring independent evidence and review. No chain lookup, independent sanctions screening, compliance clearance, or verified wallet identity is provided. | $0.10 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic LP/GP distribution waterfall for private equity, venture, and real estate. Allocates distributable cash through the standard tiers · return of capital, preferred return (hurdle), GP catch-up, carried-interest split · and returns the exact LP/GP split, per-tier breakdown, LP MOIC, GP carry, and effective carry %. The catch-up is solved so the GP lands at exactly its carry % of total profit. Pure math from caller-provided terms · no data feed, no fabrication. | $0.25 | Base | USDC | header | since 07-30 |
| POST | / | Deterministic provenance analysis for caller-supplied x402 payment records. Excludes duplicate transaction hashes, separates declared owner wallets from candidate external payers, measures concentration and evidence coverage, and states limitations explicitly. It does not fetch the chain or claim wallet independence. | $0.05 | Base | USDC | header | since 07-30 |

How the score works
What the score read on this service: status online, 100% uptime 30d, 455ms 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.
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 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 171 listings, this one among them: the same 171 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.
Settled via coinbase ($0.06, 6 tx). Traction is a conservative undercount; first settlement seen 2026-06-19.
All measured facts
What it does
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.
Hermes Plant is a listed x402 Verification API. Captured payment terms name Base. 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 volume uses the latest 30d assessment. Over time sums daily address snapshots, rounded to cents and refreshed separately. The two sources can differ in timing, precision and shared-address attribution. Amounts use cents for comparison; known sub-cent values keep up to 12 significant digits. The exact stored assessment value is shown above.
Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share lowers the on-chain traction part of the ranking score behind this page's verdict and /best, by up to half when one address holds all 30d volume. The Recommended and Highest volume sorts of the services list do not use it; they use the Concentrated volume rule instead.
