x402 API docs

Fetches a web page and returns the article as clean text and markdown, with its declared metadata.

Returns the response headers, final status, redirect chain and a security-header grade for a URL, without downloading the body.

Fetches a web page and returns every link on it, resolved to absolute, each tagged with its rel, a nofollow flag and whether it stays on the same site.

Fetches a page and returns its <head> metadata -- title, description, canonical, language, hreflang, favicon, Open Graph and Twitter cards -- with every URL resolved to absolute.

Fetches a web page and returns its embedded machine-readable data -- JSON-LD, OpenGraph, microdata and meta tags -- plus a normalised merge across all four.

Fetches a web page and returns the article as clean markdown, with its title, byline and final URL.

Follows a shortened or tracking URL to its real destination and returns every hop it went through.

Fetches a web page and returns the RSS, Atom and JSON feeds it declares in its <head>, as absolute URLs with their type and title.

Fetches robots.txt and answers whether a user agent may crawl a URL, showing the group, the winning rule and every rule that competed with it.

Fetches an RSS, Atom or RSS 1.0 feed and returns its channel metadata and a normalised list of items -- id, title, link, summary, content, author, dates and categories -- with every date in ISO 8601 UTC.

Parses a sitemap, a sitemap index or a bare origin into a flat, bounded list of URLs with lastmod, changefreq and priority.

Fetches and parses a domain's well-known files -- security.txt (RFC 9116), ads.txt and humans.txt -- returning typed fields, seller records and a cross-file summary in one call.

DNS records for a domain (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA) with their TTLs.

Validates an email address: syntax, MX records for its domain, and whether it is a disposable or role account.

Reverse DNS (PTR) and network ownership for an IP address or a domain.

Fetches the TLS certificate a host presents: issuer, subject, SAN list, validity window, days to expiry and the full chain.

Registration record for a domain over whois: registrar, creation/update/expiry dates, status codes and nameservers, with the raw response.

Parses a CSV/TSV document into JSON rows, keyed by a header row or as arrays; the delimiter is auto-detected.

Converts a Word .docx to Markdown, surfacing anything that did not translate as warnings.

Extracts an EPUB’s reading-order text and Dublin Core metadata, chapter by chapter.

Renders a web page or an inline HTML string to a PDF, returned base64-encoded with its page count.

Renders JSON objects as raw CSV with no spreadsheet formula protection; columns are inferred or given, nested values are JSON-encoded.

Renders a Markdown document to a PDF, returned base64-encoded with its page count.

Reads the text out of an image (scan, screenshot, photo) with Tesseract, returned with a mean confidence.

Concatenates 2–8 source PDFs, in order, into one PDF returned base64-encoded. Maximum output PDF size: 25 MiB before base64 encoding.

Reads a PDF's page count, document-info fields, version and encryption flag without rendering it.

Extracts a 1-indexed page selection (e.g. "1,3-4") from a PDF into one new PDF, returned base64-encoded. Maximum output PDF size: 25 MiB before base64 encoding.

Converts a PDF to Markdown, inferring headings from font size (best-effort, not layout-perfect; no OCR).

Extracts the text layer of a PDF, page by page, in reading order (no OCR).

Extracts the slide text of a PowerPoint .pptx, slide by slide, in order (body text only, up to 1,000 slides).

Reads an Excel .xlsx into JSON rows, keyed by a header row or as arrays; dates become ISO strings. Archives are limited to 64 worksheets.

Extracts an image's dominant colours as a small palette (hex, RGB and coverage fraction).

Discovers a page's favicons and returns the best one decoded to a normalised PNG with its size.

Re-encodes an image in its own format at a lower quality to shrink the file, keeping its dimensions.

Transcodes an image to PNG, JPEG or WebP at a chosen quality, returned base64-encoded.

Reads an image's EXIF/ICC/IPTC/XMP metadata and can return a copy with all metadata stripped.

Reports an image's format and pixel dimensions from its header, without decoding the pixels.

Resizes an image to a target width/height under a chosen fit, returned base64-encoded.

Rasterises an SVG to a PNG at a chosen resolution, returned base64-encoded.

Transcodes an audio file between WAV, MP3, FLAC, AAC and Opus, with an optional bit rate and sample rate.

Extracts the audio track from a video (or any container) and returns it in a chosen audio format.

Reads a media file's container, duration, bit rate and per-stream codec/resolution without decoding it.

Converts a subtitle track between SubRip (.srt) and WebVTT (.vtt), normalising the cues.

Extracts a text subtitle track from a media container (MKV, MP4, WebM) as SubRip or WebVTT.

Grabs a single frame from a video at a chosen timestamp as a PNG or JPEG, optionally scaled to a width.

Reduces an audio file to a fixed number of normalised waveform peaks for drawing, without shipping samples.

Extracts one named entry from a remote zip, tar or tar.gz and returns its bytes (base64) with a sha256.

Lists the entries of a remote zip, tar or tar.gz (paths, sizes, compression and CRC) without extracting any of them.

Detects a remote file's true type from its magic bytes, returning the canonical extension and media type.

Computes the sha256, sha1 or md5 digest of a remote file, buffered in memory under a size cap, for checksum verification.
