Decode a 17-character VIN: ISO 3779 structural validation (check digit), WMI manufacturer lookup, model year, and NHTSA vPIC pattern decode (make, model, trim, body, engine, plant). Public-domain NHTSA data.

Validate a blockchain address. Supply `chain` to check against a specific chain, or omit it to auto-detect. Ethereum addresses report their EIP-55 checksum state; Bitcoin covers base58check (P2PKH/P2SH) and bech32/bech32m segwit (P2WPKH/P2WSH/P2TR). A well-formed but invalid address returns `valid:false` — not an error.

Checks one address on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain against the open verification registry and against the chain itself. For a proxy the answer is deliberately split in two: whether the proxy is verified says almost nothing, whether the implementation it currently points to is verified is the real question, and both are reported separately with the implementation a

Check a URL before fetching it: is it alive, final URL after redirects, HTTP status, content type, HTML title, and whether robots.txt allows your user-agent. Link checker and fetch preflight for agents.

Two checks in one. First the arguments are validated against the tool input schema and every violation is reported with its path and a sentence saying what to change. Second, values that satisfy the schema but look wrong are flagged: an unset required field filled with a placeholder like "string" or "TODO", a number at a suspicious order of magnitude, an address that fails its checksum shape, a de

Fuzzy-screen a name against OFAC SDN, UN, EU, UK, Swiss SECO, World Bank debarment and US BIS/State/Treasury non-SDN lists (optional lists= filter): matches with list, id, primary name, matched alias, score, type, programs, countries, dates of birth, listing date and reference, plus the date each list was checked.

Check a public website before deploy: test mobile website layout, accessibility, browser errors and screenshots across three viewports

Every agent and developer hits broken or confusing JSON. This tool handles the common headaches in one place: check whether JSON is valid with the exact error location, repair near-JSON with typos, pretty-print or minify, pull values out with a path expression, diff two documents, convert to and from YAML or CSV, produce a byte-stable canonical form for hashing, validate against a schema, and repo

Ultra-processed food check for one real product — scan a barcode (EAN/UPC) and get the NOVA processing group, Nutri-Score, full additive census with flagged-additive notes (EU-banned dyes, IARC-listed sweeteners, nitrites), added sugar/salt/saturated fat per 100g, and a plain verdict. Live Open Food Facts data (3M+ products, global), deterministic, no LLM.

Pre-payment risk and usefulness check for AI agents deciding whether to pay an x402 endpoint.

Use this service before importing or publishing JSON to check it against a restricted draft-07 schema. Send dataJson and schemaJson as JSON-encoded strings. Max 256 KiB UTF-8 each, depth 32; bounded node and work limits. Supports types, required properties, items, enums and numeric/length bounds. No regex, combinators or external references. Invalid business data returns valid=false.

Parser-blocking script budget repair plan 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.

Which x402 endpoint should I call? Describe the job in plain words; get the 3 best endpoints from different providers, each health-checked live just now, with its current price quote, its inputs and the reasons — ranked over the whole Coinbase Bazaar catalog by fit, real paying demand and health. Uncharged when nothing passes.

Check whether a domain's TLS/SSL certificate is valid, trusted, and not expiring before connecting to it. Performs a live handshake and returns a 0–100 score and tier (VALID/WEAK/EXPIRING/EXPIRED/UNTRUSTED/INVALID) with chain trust, days-to-expiry, signature algorithm, TLS version, and cipher quality. Use before submitting credentials, posting to a webhook, or following a payment link, to catch ex

Verify a claim or fact check a statement against public web sources: send a question and up to 5 URLs, get cited evidence - passages that support, contradict or fail to settle it. Claim verification with a citation for every excerpt: source URL, retrieval time, content hash. Never charges when nothing is retrieved. Free to evaluate: the `sample` tool returns one real response at no cost, so you ca

Returns whale, CEX, bridge, and stablecoin flow alerts for a chosen chain and lookback window, each with direction, venue, and USD value — use it to catch large capital movements before they move price. Typical agent tasks: check for a large exchange inflow on Base, monitor bridge flows into or out of a chain, track stablecoin issuer mint or burn events, or add on-chain flow context to a crypto ma

Base token risk check before a swap: send a token contract address, get ok / caution / avoid with reasons. Reads the contract (ERC-20 metadata, owner, upgradeable proxy, mint / pause / blacklist / fee selectors in bytecode) and its DEX liquidity (Uniswap + Aerodrome pools, read on-chain). Deterministic, no LLM.

Overwing guardrail: check text before you send, post, or act on it. Content moderation, PII detection, confidential leak detection, toxicity, self-harm and severity in ~150 ms. Returns a verdict plus one recommended_action (block / redact / review / allow) with calibrated confidence.

Resolve a 20-character Legal Entity Identifier (LEI, ISO 17442) to its authoritative entity record: verified legal name, registration status (ISSUED/LAPSED/RETIRED), entity status, jurisdiction, legal form, registration number, legal and headquarters addresses, key dates (registration, last update, next renewal), managing LOU, corroboration level and any BIC codes. ISO 7064 check digits are verifi

Is this x402 endpoint safe to pay? Vet an unknown seller BEFORE paying: pay/avoid verdict, 0-100 trust score, live 402 probe, scam flags (payTo hijack, bait-and-switch pricing, honeypot, wrong asset) and an on-chain check of the receiver on Base. Reads x402 v1 (body) AND v2 (PAYMENT-REQUIRED header) — body-only checkers call live v2 services dead. ?endpoint=url; omit for a trust-ranked catalog.

Performs comprehensive URL health checks, measuring response time, status code, security headers, and TLS/SSL certificate validity. Route: GET /paid/health-check?url=https://example.com. Ideal for automated monitoring and endpoint auditing.

Base token risk report with an AI-written plain-English summary. Checks what most scanners miss: whether the creator or launch wallet can pull the pool liquidity (incl. Uniswap V4), copycat tokens reusing a bigger token's ticker, and Clanker/Doppler/B20 launch platforms. Also honeypot and taxes, mint/pause/blacklist powers, upgradeable proxy, ownership and holders. Returns a 0-100 score, LOW/MEDIU

Send any x402 resource URL, get a trust verdict on the endpoint itself. Returns TRUSTED / CAUTION / AVOID with a 0-100 score from an observation-only live probe (never pays the target): payment terms, Bazaar discovery-schema quality, CDP Bazaar and PayAI catalog presence, plus a diff against the previous check.
