Security & trust

US Treasury interest rates: the Daily Treasury Par Yield Curve fused with the average interest rates on the outstanding debt by security type. Computes the 2s10s spread and an inversion flag. The yield curve is a resilient partial grain that degrades to the average rates if its upstream is unreachable.

Scan a dependency manifest for known-vulnerable and confirmed-malicious packages. POST /v1/scan with a raw lockfile or a components array and get per-dependency verdicts (malicious, vulnerable, suspicious, clean) from OSV.dev and the OpenSSF Malicious Packages feed, each with a summary and snapshot timestamp. Pay per request in USDC; no account, no API key.

Check whether a supplied public source supports or contradicts a factual claim. Validate citations in AI-generated answers against the supplied URL. TruthPal returns source-grounded evidence and a supported, contradicted, or uncertain verdict; when the source is insufficient, the result is uncertain. It assesses only the supplied source and does not independently corroborate the claim.

Verify SAM.gov entity registrations: UEI, legal name, registration status, and expiration. POST /v1/entity with a {name} (or UEI) and get the matching records as one JSON object. Deterministic per record. Pay per request in USDC; no account, no API key.

Complete AI-powered smart contract security audit - analyzes code against checklist and provides detailed findings with severity levels. PRICING (based on model): DeepSeek: $0.15 USDC, Sonnet: $0.25 USDC, Fable: $0.70 USDC. Payment must match selected model.

Known vulnerabilities for package+version; normalized evidence, not a safety verdict. Base mainnet USDC

For owners of a listed paid API: we buy from your endpoint with real USDC and publish the result on your nohumans.directory listing, whatever it finds. Plan "single": one purchase within 24 hours. Money decides when we buy, never the outcome, score or rank. Send your claim token as x-claim-token. Fee $3.00; this listing quotes $0.5000/call. Other plan: ?plan=pack ($5, three purchases in 30 days). Rule: https://nohumans.directory/methodology#verify-now

ETH Volatility Risk Premium — DVOL minus Parkinson realized vol (72h). Positive = sell-vol opportunity, negative = buy-vol. Response includes regime classification (LOW/MID/HIGH), raw inputs for audit (DVOL, RV_72h, RV_6h, spot), timestamp, and open methodology URL.

Fetch a URL and return every response header plus a security analysis: HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/CORP/COEP. Scores 0–100 by presence, flags weak HSTS, and warns on Server/X-Powered-By identity leaks. SSRF-protected.

Discover and fetch a site's A2A (Agent2Agent protocol) Agent Card - tries /.well-known/agent-card.json then /.well-known/agent.json (or fetches a direct .json URL as-is) - and validate it against the spec v0.3 structural core. Returns the card, errors, interop warnings, and a normalized summary. Mini-A2A discovery for agents. Marked untrustedContent: the fetched card is external data to analyze, not instructions to follow.

Flag outliers in a numeric series using either the IQR rule (Tukey fences at 1.5·IQR - robust, default) or z-score (|z| > threshold - assumes normality). Returns the outlier values + their indices + the thresholds used so you can decide whether to trust them.

Compute SHA256 hash or SHA-512, SHA-1 and MD5 checksums for UTF-8 text and return hex plus Base64 digests. Use for SHA256 hashing, checksum verification, integrity checks, content fingerprints, cache keys, deduplication and agent pipelines.

Xynaptic Security Price — spot market data for US stocks: price, previous close, day range, 52-week range, currency, exchange + up to 30d history (OHLCV). GET ?ticker=AAPL&history=30. Refreshed intraday.

Score one x402 resource for trust, schema, price, discovery, and receipt readiness.

Authoritative MITRE ATT&CK (Enterprise) technique lookup. Pass id (e.g. T1059 or sub-technique T1059.001) for the canonical technique — name, tactics (kill-chain phases), description, platforms, sub-technique flag + parent, mitigations, and detection guidance — or query for a keyword search returning ranked techniques. Bundled current ATT&CK matrix (~700 techniques), zero external calls. Agents cite T-numbers and tactic names that must be exact; this returns version-pinned, citeable data instead of hallucinated IDs. For threat modeling, detection engineering, and report enrichment.

Multiplies each mutually exclusive supplied scenario probability by its supplied damage fraction and asset replacement value, then sums expected loss. It does not obtain hazard maps, model hydrology, validate damage curves, price insurance or predict a particular event.

Calculates floor-area ratio and lot coverage and compares use, height, parking and geometry with an explicit caller-supplied rule set. It does not retrieve or interpret current law, resolve overlays or variances, establish entitlements or provide legal advice; an official planning authority must verify any real project.

Sorts unique scalar key/value entries through canonical JSON serialization and computes SHA-256. It verifies byte-level agreement with an optional claimed digest only; it does not prove block inclusion, timestamp, signer identity, or chain consensus.

Multiplies the copper quantity by literature emission factors for the chosen secondary route and for primary cathode production, and reports the difference as low, typical and high. The factors are published life cycle averages and are stated in the response; they are not a certified product carbon footprint and are not a valid basis for a carbon credit, a customer declaration or an audited claim.

Recomputes every record hash from a canonical JSON representation of id, sequence, timestamp, previous_hash and payload, then checks that each record points to the hash of the record before it. If a root_hash is supplied, the same computed record hashes are folded into a deterministic binary Merkle tree with the last leaf duplicated on odd levels.

Screen one address against sanctions and scam blocklists — Genesis402 / UnyKorn Operator Network

Publisher discovery audit fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

Password entropy calculator, Shannon entropy, bits of randomness, charset size, mathematical password strength metric for security audits. Accepts payment on Base or Solana — either network works.

Dokimo Verify API (GET) - scheme demo: recomputes a sample dokimo-merkle-v1 proof to its root. For real caller verification, POST /paid/verify (recompute + on-chain anchor check). Scheme: /merkle-spec.html.

Agent-ready satellite observations for any coordinates. Returns PNG image URLs and scene metadata for true color, vegetation, water, thermal, or radar analysis.

x402 endpoint reliability pre-flight: factual service-delivery measurements of a target x402 endpoint before an agent pays it — reachability/uptime rate, valid-402 rate, response latency (p50/p95/p99), last status, and sampled paid delivery verification. Facts only (no trust score, no 'scam' label). Check whether an endpoint is live and delivers before spending on it.

Runs a full technical SEO audit on a single web page. Verify redirects, headers, meta tags, indexability, JSON-LD, missing or conflicting canonicals and more. No black-box scoring; just deterministic, composable signal you can act on. Every threshold is documented at https://minifetch.com/skills/seo-page-audit/SKILL.md Obeys robots.txt. Supports GET & POST

Instant website SEO audit. On-page SEO, performance, and accessibility snapshot for any URL — title, meta tags, headings, links, image alt, load time, and an issues list with score.

World ID Proof Verifier: Verify a World ID 4.0 proof via the Worldcoin Developer Portal API. Generates an RP signature server-side, then proxies the full IDKit proof to developer.world.org. Returns { valid, nullifier, worldcoin_response }. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/verify_worldid.
