Profiles the token's creator wallet: how much history it has, how much of the supply the creator still holds, and whether ownership is renounced — rolled into a 0-100 reputation score with signals. A fresh wallet holding 20% of supply with no renounce is the classic rug setup; this is the forensics layer other checks skip.

Look up a product barcode number: identify and validate EAN-13, EAN-8, UPC-A, UPC-E, GTIN-14, ISBN-13/10, ISSN and ISMN codes (wrong check digits are reported with the correct digit), convert between forms (GTIN-14, EAN-13, UPC-A, ISBN-10 <-> 13) and decode the GS1 prefix. Then fetch product data from open databases: name, brand, quantity, categories, image, labels, Nutri-Score (food, cosmetics, pet food via Open Food Facts) or title, authors, publisher and cover (books via Open Library).

Validate an Indian GSTIN by structure (2-digit state code + PAN + entity code + 'Z') and its mod-36 cross-sum checksum.

Regex From Examples for Any Script — Writes a JavaScript regular expression from a description plus lists of strings that must match and must not match, answered as JSON with the pattern and flags. Knows the traps measured in Node 24 - \b and \w are ASCII-only even with the u flag, so \bдума\b never matches Cyrillic text and \w+ cuts "café" to "caf"; a word boundary for any script is a pair of lookarounds with \p{L} and the u flag. Anchors a validator so extra text around the value is rejected,…

Log Lines to JSON Lines, Odd Lines Kept Raw — Parses plain-text log lines into JSON Lines, one record per line, by a format the task states (Apache or nginx combined access log, RFC 5424 syslog, key=value pairs, or a custom pattern with named fields). Splits by the format's grammar and not by spaces, so quoted fields with spaces and escaped quotes stay whole. A dash that the format defines as absent becomes null, fields the task calls numbers become JSON numbers (a status stays a number, a zero…

Ask typed questions about up to 4 images (PNG or JPEG) and get answers your code can branch on: noul (yes/no probability), choice, score, and box (where something is, as edges from 0 to 1). Name each image, then refer to it as `name` in a question. Preview: built on Jev features its maker labels experimental. Answers come from a model, not deterministic code.

Tell me what changed on this page since my last check (deterministic, no LLM)

Describes what is in an image in about one second: pass an https URL or base64 and ask anything about it, from a one-line caption to reading a sign. Pairs with the rest of the chain: describe an image, translate the description, then have it read aloud. You are only charged if the description is delivered. No API key, no account.

MQTT service discovery (_mqtt._tcp.<domain>): SRV records with priority, weight, port and target host, from Cloudflare DoH. Tells a client where the domain's mqtt service lives without guessing hosts. $0.01 per lookup.

A record of forum.<domain>: looks up the forum host under the domain you give (A via Cloudflare DoH) and reports whether it exists, its records and TTL. Quick existence check for common hosts like forum without enumerating subdomains. $0.01 per lookup.

Deploy applications to Cloud Run

Review and rewrite LangChain, LlamaIndex, Ollama, and XRPL code against current APIs.

Cross-cloud GPU orchestration CLI.

Use when a Brazilian postal code needs to become a real address — filling a form, validating a delivery, completing a customer record. JSON body { cep } (8 digits). Returns street, complement, neighborhood, city and state (UF). Queries BrasilAPI first and falls back to ViaCEP automatically, so one upstream outage does not fail the task; both sources return the same normalized shape. CEP is postal/geographic data, not personal data.

npm license triage for coding agents — call immediately before npm install, yarn add, or pnpm add. Returns npm-declared license, SPDX id, and permissive-default compatible (yes | no | unknown) so the agent can proceed, swap package, or escalate. Not SBOM, not legal advice. Free taste: GET /license/check/preview (same JSON, $0), then pay GET /license/check or MCP check_npm_license for the package you will install.
