What this API covers
Use the endpoint that matches the task and input media. The routes below are enabled Muapi model IDs checked against the current model catalog; availability, request fields, and pricing can change, so verify the linked landing page and endpoint schema before production use.
| Endpoint | Purpose | Category |
|---|---|---|
ai-image-upscaler | Image Upscaler | Image to Image |
seedvr2-image-upscale | Image Upscale | Image to Image |
topaz-image-upscale | Image Upscale | Image to Image |
Quick start
Muapi uses an asynchronous REST contract. Submit a JSON request with your API key, save the returned request_id, then poll the result endpoint. Replace sample URLs with files you control and fields with values supported by the selected endpoint.
curl -X POST https://api.muapi.ai/api/v1/ai-image-upscaler \
-H "Content-Type: application/json" \
-H "x-api-key: $MUAPI_API_KEY" \
-d '{
"image_url": "https://example.com/replace-with-your-file"
}'
Request fields in this example
| Field | Requirement | Notes |
|---|---|---|
image_url | Required | URL of the input image. |
Poll for the result
curl "https://api.muapi.ai/api/v1/predictions/$REQUEST_ID/result" \
-H "x-api-key: $MUAPI_API_KEY"
Poll until the task status is completed or failed. Read the response’s output URLs on completion; download outputs you need to retain, since provider-hosted URLs may expire.
Choosing an endpoint
Compare supported inputs and output behavior first, then resolution, duration, quality controls, latency, and price for your use case. Similar names do not guarantee interchangeable request schemas. This repository lists representative routes; the canonical landing page contains the current task-specific explanation, examples, and pricing context.
Errors and production notes
- Keep the API key in an environment variable; do not commit credentials.
- Validate inputs against the selected endpoint’s current schema.
- Handle non-success HTTP responses and failed task states explicitly.
- Retry only when appropriate for the error; avoid submitting duplicate billable jobs after a timeout without checking the original
request_id. - Confirm current pricing and availability on the Muapi page before estimating production cost.
