Output

Creating a task does not mean generation has finished. Keep its id, poll until succeeded or failed, then read outputs or error. Amounts below are illustrative; actual charges depend on the request.

Get the result

Poll every few seconds until status is succeeded or failed. Output URLs are provider-hosted and may expire — download them promptly. Or pass callback_url to get the result pushed.

curl "https://01router.com/api/v1/generations/GENERATION_ID" \
  -H "Authorization: Bearer $API_KEY"

queued → processing → succeeded / failed. Stop polling at either terminal state. Result URLs. Empty while processing; read after succeeded and save the files promptly.

Cancel a task

Cancellation depends on provider support and task state. A confirmed cancellation returns status: failed and error: Canceled by user. Unsupported or completed tasks return 409 not_cancelable.

curl -X POST "https://01router.com/api/v1/generations/GENERATION_ID/cancel" \
  -H "Authorization: Bearer $API_KEY"

Quote

Choose API quotes or frontend quotes: the API returns costs for currently available providers; frontend quotes read prices and billing fields from models and recalculate locally when inputs change.

curl "https://01router.com/api/v1/quote" -H "Content-Type: application/json" --data-binary @- <<'JSON'
{
  "model": "gpt-image-2.6-flare",
  "input": {
    "prompt": "A cinematic shot of a red fox running through snow",

    "quality": "medium",
    "num_images": 1

Prompt API

Public read-only endpoints: no API key or credits required. Browse published examples for active models using combined model, source and scene filters.

curl "https://01router.com/api/v1/prompts?model=gpt-image-2.6-flare&locale=en&page=1"
curl "https://01router.com/api/v1/prompts/PROMPT_ID?locale=en"

Use modelSlug and prompt to construct the request body below for POST /generations. Generation still requires an API key and incurs model charges. Query GET /models/gpt-image-2.6-flare for any additional required inputs.

OpenAI-compatible images

For OpenAI SDK integrations, use this endpoint with top-level prompt. It waits for the result and returns data[].url. For asynchronous tasks and the full model parameter set, use /generations.

  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" --data-binary @- <<'JSON'

Model schema

This public endpoint returns the model parameters and each provider’s supported constraints and prices.

curl "https://01router.com/api/v1/models/gpt-image-2.6-flare"

Errors

Check the HTTP status and error.message. Fix the request before retrying validation or authentication errors. A failed generation is reported in status and error on the task itself.

{
  "error": {
    "message": "Invalid or missing API key",
    "code": "unauthorized"
  }
}

400Invalid body or parameter value

401Missing or invalid API key

402Not enough credits

404Unknown model or generation

409The task cannot be canceled (already finished, or the provider does not support canceling)

429Too many requests — retry after the given seconds

502Every provider rejected the task (credits refunded)
