Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/image/from-htmlWhen to prefer
Choose this endpoint when you need to convert raw HTML/CSS markup into a pixel-accurate image without managing a browser or Puppeteer instance yourself. Ideal for generating social preview cards, rendering email templates, producing shareable screenshots from dynamic HTML, or creating image assets from templated markup — all via a simple paid API call with no infrastructure overhead.
Side effects
- Invalid or malformed HTML may produce blank or broken images
- External resource references (CDN fonts, remote images) may not load inside the sandbox
- Overly large HTML or complex CSS may cause rendering timeouts
- Missing or empty HTML body returns an error
- Payment insufficient — x402 minimum is 1¢ USDC
