Endpoints (20 live)

• POST /v1/mermaid — Render a Mermaid diagram (flowchart, sequence, class, state, ER, gantt, pie, mindmap, timeline, ...) to PNG, SVG or PDF. Headless Chrome, offline. Invalid syntax returns the Mermaid parser error and you are NOT charged. (0.01 USDC on Base)
• POST /v1/markdown-pdf — Convert Markdown (GFM tables, code, lists) to a clean, print-ready PDF. Fenced ```mermaid, ```dot and ```math blocks and $$...$$ display math are rendered as vector graphics inside the PDF. Offline: remote resources are not fetched (use data: URIs for images). Render errors are returned and you are NOT charged. (0.01 USDC on Base)
• POST /v1/math — Typeset a LaTeX/TeX math expression (MathJax, AMS packages) to PNG, SVG or PDF. TeX errors are returned and you are NOT charged. (0.01 USDC on Base)
• POST /v1/ocr — OCR: extract text from an image (PNG, JPEG, WebP, TIFF, GIF, BMP) or a scanned PDF (up to 5 pages) with Tesseract 5 LSTM, in a network-less sandbox. Send base64 in "image" (up to ~8MB) or a public "url". Languages: eng, deu, fra, spa, por, ita, rus, chi_sim, jpn (combine with +). Returns text with paragraph/line structure, per-page confidence and optional word boxes. No text found = NOT charged. (0.005 USDC on Base)
• POST /v1/screenshot — Screenshot any public web page in a real headless Chrome (JavaScript executed, waits for network idle). Viewport or full-page, CSS-selector element capture, desktop/laptop/tablet/mobile presets, dark mode, hide cookie banners via selectors; PNG, JPEG, WebP, or a print PDF of the page. Blocked/unreachable pages, HTTP >= 400 and robots.txt-disallowed URLs are NOT charged. (0.005 USDC on Base)
• POST /v1/search — Search ~18,000 paid x402 APIs on Base (merged CDP Bazaar + PayAI Bazaar + x402scan + 402index) in plain language. Returns ranked matches scored by relevance, 30-day paid usage, uptime and a live health probe done at query time (valid Base-USDC x402 challenge, live price, latency), each with its input fields, a ready-to-run example request and a /v1/concierge body. Dead, scammy and test endpoints are filtered out. (0.002 USDC on Base)
• POST /v1/read — Read any public URL as clean, LLM-ready Markdown. Pages are rendered in a real headless Chrome first, so JavaScript-heavy sites (SPAs, React/Next, lazy content) work where plain HTTP fetchers return empty shells. Mozilla Readability extracts the main article (or mode=full keeps the whole page); tables become GFM tables. Also returns title, byline, description, language, canonical URL, links. PDFs are converted to text. HTTP errors, empty pages and robots.txt-disallowed URLs are NOT charged. (0.003 USDC on Base)
• POST /v1/graphviz — Render a Graphviz DOT graph to PNG, SVG or PDF (engines: dot, neato, fdp, sfdp, circo, twopi, osage, patchwork). Syntax errors are returned and you are NOT charged. (0.01 USDC on Base)
• POST /v1/concierge — Ask for anything, get the result, one endpoint. render402 concierge is an aggregator: describe what you need in plain language (weather, prices, web search, company data, screenshots, speech, translation, ...) with a maxPrice; we route it to a vetted, live-checked third-party x402 service on your behalf, pay that service ourselves, and return the result in one consistent envelope. You never need to discover, vet or pay individual APIs. Price is quoted in the 402 (simple tiers, never above your maxPrice) and settled only if the task succeeds. (0.005 USDC on Base)
• POST /v1/chart — Render a chart to an image: pass a Chart.js v4 config (bar, line, pie, doughnut, radar, scatter, bubble, polarArea, mixed) -> PNG/PDF, or a Vega-Lite v5 spec -> PNG/SVG/PDF. Offline and deterministic (inline data only). Invalid configs return the library error and you are NOT charged. (0.005 USDC on Base)
