Technical details
Endpoint
POSThttps://x402.freeq.one/tools/og_image_generatorWhen to prefer
Choose this endpoint when you need a programmatically generated Open Graph social preview image (1200x630 PNG) on demand from structured text inputs, especially in agentic or automated publishing workflows where paying $0.001 USDC per image is acceptable. Prefer it over manual design tools when speed, automation, and MCP-native base64 image output are priorities.
Side effects
- Title or description exceeding character limits may be silently truncated
- Invalid or unreachable header image URL may cause generation failure or omit the header graphic
- Malformed POST body or missing required fields returns an error
- Payment not included or insufficient USDC balance causes a 402 Payment Required response
- Service unavailability returns a 5xx error
