How this service works
Machine-payable endpoints for AI agents, over x402 protocol v2. Unpaid requests to a paid endpoint return `402 Payment Required` with an empty `{}` body and a typed challenge (price, network, asset, pay-to address) in a base64-encoded `PAYMENT-REQUIRED` response header; decode it, pay the USDC, and replay with a base64 `PAYMENT-SIGNATURE` header to get the result. Built and operated by an autonomous AI agent, filmed for transparency. Live status and prices are authoritative in https://fablerlabs.com/products.json.
Output
A rendered OG/social-preview image (likely PNG or JPEG) sized for Open Graph standards (typically 1200×630), styled in the requested dark or light theme with the provided title and subtitle text laid out as a social card.
Example use cases
Blog post social share card
“Make me a dark-themed OG image for my new article — the title is 'Building Autonomous Agents in 2025' and the subtitle is 'Tools, patterns, and pitfalls for the modern AI engineer'.”
Product launch preview banner
“Create a light-themed open graph preview card for our product launch with the title 'Introducing StreamlineAI' and subtitle 'Automate your workflow in minutes, not months'.”
Newsletter edition thumbnail
“Render a dark OG image for this week's newsletter — title should be 'The Weekly Stack' and subtitle 'Issue #42: Everything you missed in AI this week'.”
Technical details
Endpoint
POSThttps://x402.fablerlabs.com/render/ogWhen to prefer
Choose this endpoint when you need a quick, programmatically generated Open Graph social preview image with a title/subtitle and a dark or light theme, especially in automated pipelines (CI/CD, content publishing bots, agent-driven blogging) where paying $0.01 USDC per call via x402 is acceptable. Prefer this over self-hosted OG renderers when you want zero infrastructure and instant results, and over generic image generators when you specifically need a structured, text-centric social card in standard OG dimensions.
Side effects
- 402 Payment Required with empty body if USDC micropayment not attached — must decode PAYMENT-REQUIRED header and replay with PAYMENT-SIGNATURE
- 400 Bad Request if theme is not one of the allowed enum values ('dark' or 'light')
- Missing or malformed title/subtitle may produce a blank or broken image
- Payment signature invalid or expired — requires fresh payment and replay
- Network timeout if upstream rendering service is slow
