# MimirAPI Open Graph Image Generator

> MimirAPI Open Graph Image Generator is a paid API for AI agents from mimirapi.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Generates a deterministic 1200x630 SVG social card (Open Graph image) from a title and optional subtitle, in dark or light theme, with byte-identical output for identical inputs.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mimirapi-open-graph-image-generator-868c337f
```

Example prompt: Generate a dark-theme Open Graph social card SVG for my blog post titled 'Why AI Agents Will Change Everything' with the subtitle 'A deep dive into autonomous systems'.

## When to prefer this

Choose this endpoint when you need a fast, deterministic, no-dependency Open Graph image with no headless browser, no font pipeline, and guaranteed byte-identical output for the same inputs. Ideal for agents building or publishing web pages programmatically where reproducibility and low latency matter more than custom branding or pixel-perfect design. Prefer this over screenshot-based OG image services when you want a pure SVG, consistent caching behavior, and simple text-based input.

## Known failure modes

- Missing required 'title' query parameter returns an error
- Title exceeding 120 characters may be rejected or truncated
- Subtitle exceeding 200 characters may be rejected
- Invalid theme value (not 'dark' or 'light') returns a validation error
- Payment failure (x402) results in a 402 response before any SVG is generated
- Network timeout on the provider side could return a 5xx error

## How this service works

Deterministic 1200x630 social-card SVG from a title and optional subtitle, dark or light theme. Same input, byte-identical output — an agent building pages gets an Open Graph image in one call with no headless browser and no font pipeline.

## Output

Returns a deterministic SVG string at 1200x630 pixels suitable for use as an Open Graph og:image meta tag, along with width, height, and contentType fields. The same title/subtitle/theme inputs always produce byte-identical SVG output, so the result can be safely cached or fingerprinted.
