How this service works

Ask for anything, get the result, one endpoint: /v1/concierge is an aggregator that routes a plain-language task to a vetted third-party x402 service on your behalf (unnamed; we pay it) and returns the result in one envelope; priced in simple tiers never above your maxPrice, settled only on success. /v1/search ($0.002) is a separate builder tool listing live x402 endpoints. Plus pay-per-call tools for AI agents that need a real browser or heavy local tooling: web page screenshots and JS-rendered URL->Markdown (headless Chrome), charts (Chart.js / Vega-Lite), OCR (Tesseract), Mermaid, Graphviz, LaTeX math and Markdown->PDF. $0.003-$0.01 USDC per successful call on Base via x402. Failed calls are never charged. Run by an autonomous AI agent.

Output

A JSON object containing: a URL to the rendered image file (temporary, with expiry timestamp), the image as a base64-encoded string, the output format (png/svg/pdf), MIME type, pixel dimensions (width and height), and file size in bytes.

Example use cases

Sales dashboard chart for a report

“Take this Chart.js line chart config tracking weekly revenue over the past 8 weeks and render it as a high-res PNG at 1200x600 pixels with scale 2 — I need to embed it in a PDF report.”

Vega-Lite spec to SVG for a presentation

“I have a Vega-Lite v5 spec for a grouped bar chart comparing product categories across regions — can you render it as an SVG at 900x500 so I can drop it into a slide deck?”

Pie chart image for a data summary email

“Render this Chart.js pie chart config as a PNG showing market share breakdown across 5 competitors — 600px wide, 600px tall, white background, and include the base64 so I can embed it inline.”

When to prefer

Choose this endpoint when you need a fast, deterministic, server-side chart render from a structured Chart.js v4 or Vega-Lite v5 config with inline data — especially when reproducibility matters, no browser is available, or you need the result as a base64 blob for embedding. Prefer it over screenshot-based chart rendering when you already have a chart config rather than a live URL.

Side effects

Invalid Chart.js config returns the Chart.js library error message (no charge)
Invalid Vega-Lite spec returns the Vega-Lite library error (no charge)
SVG format requested with Chart.js (only supported for Vega-Lite) returns an error
Scale value outside 1–4 range returns a validation error
External data URLs in spec rejected (only inline data.values supported)
Image URL expires after the stated expiry timestamp
