Inference
Images
Generate, edit, and vary images. Billed per image plus the network fee.
All three image endpoints are [OI]-compatible and use the same auth and balance gates as chat. Uploads are capped by the global 10 MB body limit.
Generate
POST
/v1/images/generationsAPI keycurl -X POST https://api.relayrouter.org/v1/images/generations \ -H "Authorization: Bearer $RELAY_API_KEY" \ -H 'content-type: application/json' \ -d '{ "model": "image-model", "prompt": "a minimal black and white poster", "n": 1 }'n is clamped to 1–10. The response is the upstream JSON (typically a list of URLs or base64 data) passed through unchanged.
Edit and vary
curl -X POST https://api.relayrouter.org/v1/images/edits \ -H "Authorization: Bearer $RELAY_API_KEY" \ -F [email protected] \ -F prompt="make it monochrome" \ -F model=image-modelBilling
Image calls are billed per generated image using the model's image_micro, plus the network fee. The exact charge is always in usage_logs.cost_micro; use /usage rather than recomputing media prices client-side.
/api/v1/images/generations, /edits, and /variations are aliases of the same handlers.
