Convert a number's string representation from one base (2-36) to another.

Convert an integer (1-3999) to a Roman numeral, or a Roman numeral back to an integer.

Rank up to 50 documents by relevance to a query in a single call - each document returned with its relevance probability, sorted highest first. Powered by Jev (TypeSafe System One). $0.001 per call, no OpenRouter or TypeSafe account needed. Try GET /rank/sample.

Convert text between case styles: snake_case, camelCase, PascalCase, kebab-case, Title Case, CONSTANT_CASE.

Convert an ISO 8601 datetime from one IANA timezone to another (handles DST automatically).

Parse a date/time string (ISO 8601 by default, or a given strptime format) into its components.

Convert a value between units of length, mass, volume or temperature (C/F/K).

Text in an image `url` via Google Lens: paragraph, sentence and word-level detections with bounding boxes. Optional `language`. Cheap OCR for screenshots, receipts, signs, slides.

Captures a full-page screenshot of one public web page in Chromium and returns a link to the PNG. Use it for a one-off visual check of a page, or to keep a reference image before a change. 0.02 USD per call.

Publish agent-generated files, JSON reports, markdown, or text and return a stable public URL.

Parse CSV/TSV (RFC 4180) into a JSON array of row objects (or arrays).

Locate a free open-access PDF for a DOI. Returns whether an open-access copy exists and the best PDF link with its license, version and host type, from Unpaywall and OpenAlex. A cheap, focused open-access locator.

Convert an image between formats (PNG, JPEG, BMP). Send a base64 image and the target format; returns the converted image. Optional jpeg quality (1-100). Deterministic, no network.

Combine several PDFs into one, in order. Body: {"urls":["https://…/a.pdf","https://…/b.pdf"]}. Returns the merged PDF as base64 plus page count and size.

Validate a JSON document against a JSON Schema (draft-07 subset) and get the list of violations. Supports type, required, properties, items, enum, const, min/max, length, pattern, format, anyOf/allOf/oneOf/not, additionalProperties. Deterministic - check an agent's structured output before you trust it.

Fetch a PDF from a URL, extract its text, and return a concise AI-generated summary - factual, no information added beyond what's in the document. Body: {"url":"https://…/file.pdf","maxWords":200?}. Uses the same OpenAI-compatible gateway as /v1/chat/completions internally; the model that actually served is disclosed in the response.

Convert anything at a URL - HTML, PDF, or an image - to clean markdown. The 'I have a URL but it might be any content-type, give me markdown either way' workflow: HEAD-detect the content-type, branch to the right deterministic extractor (article extract for HTML, pdf-to-markdown for PDFs, OCR for images), and report token/word stats on the output so the caller can budget the result against an LLM context window.

Extract/convert the audio track of any media URL (mp4, mov, wav, m4a, ogg…) to MP3 - the "mp4 to mp3" conversion, deterministic ffmpeg, no AI. Body: {"url":"https://…/video.mp4","bitrate":"192k"?}. Returns the MP3 as base64.

Top holdings from an institutional investment manager's most recent 13F-HR filing (managers >$100M AUM file quarterly). Parses the standard SEC informationtable.xml attached to the filing - returns issuer, CUSIP, shares, USD value, and voting authority for each position. Sorted by USD value, descending. Source: data.sec.gov + filing archive.

The 'user uploaded a thing, normalize it before storing' workflow. Probe the file (image or audio/video) with media-info, decode any embedded barcodes/QRs, resize and thumbnail the image, convert it to a web-friendly format, and normalize audio loudness to broadcast standard. Six tools, one canonical normalize-on-upload pipeline that turns arbitrary user uploads into predictable storage artifacts.

Take a signup form submission and run the full onboarding workup deterministically: validate the email, score the chosen password, mint a stable internal ID, derive a URL-safe handle from the display name, generate a recovery / API secret, hash the password for storage, and verify the 2FA setup code. One pass, every step a pure-CPU call.

Validate, pretty-print, and convert JSON to CSV in one pass - the complete JSON processing workflow. JSON pipeline skill pack: one x402 payment runs 3 underlying tools (json-validate, json-format, json-to-csv); partial-success per step.

Fetch an RSS 2.0, Atom, or RSS 1.0 feed URL and parse it into normalized JSON: feed title/description/link plus items (title, link, id, published, author, plain-text summary, categories). Deterministic pure-XML parse with a lenient recovery pass for common malformations (reported in a warnings array). Item count is bounded (default 20, max 50). SSRF-guarded.

Markdown to HTML and back - a round-trip conversion that proves fidelity and gives you both formats from one input. Markdown to HTML round-trip skill pack: one x402 payment runs 3 underlying tools (markdown-to-html, html-to-markdown, text-diff); partial-success per step.

Convert CSV into a GitHub-flavored Markdown table (first row is the header).

Parse CSV (quoted fields supported) into a JSON array of objects, using the first row as headers (header=false for arrays).

Score an OpenAPI 3.x or Swagger 2.x spec on agent-readiness - i.e. does an LLM-driven caller have what it needs to call the API correctly without guessing. Returns a 0..100 score, severity counts, and a structured list of violations with stable rule codes. Checks: documented title/servers/paths, per-operation summary/description/operationId/tags, documented 2xx + error responses, param descriptions/schemas/examples, response descriptions, JSON response schemas.

Build a runnable curl command for one operation in an OpenAPI 3.x or Swagger 2.x spec. Locate the operation by operationId (preferred) or by method + path, substitute path parameters using the spec's example values, include required query and header parameters with their example values, and attach a JSON body when the operation defines one. Returns the structured request (method, url, headers, body) alongside the assembled curl string with POSIX single-quote escaping.
