Quickstart

Get your first forecast in under 5 minutes.

1. Get your API key

Contact the eomer.ai team to receive a Bearer token. Keys are issued per client and can be rotated at any time without downtime.

2. Check the API is up

curl https://eomer-api.onrender.com/health

Expected response:

{
  "status": "ok",
  "version": "0.1.0",
  "timestamp": "2026-01-01T00:00:00+00:00",
  "checks": {
    "upload_dir": "ok",
    "output_dir": "ok"
  }
}

3. Submit a forecast job

Prepare a CSV file with at minimum three columns:

Column	Description
item_id	Series identifier (e.g. store_A)
timestamp	ISO-8601 datetime or date string
target	Numeric value to forecast

curl -X POST https://eomer-api.onrender.com/forecast \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@data.csv" \
  -F "prediction_length=24" \
  -F "presets=chronos_tiny"

The API returns immediately with a job ID and status pending:

{
  "job_id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
  "status": "pending",
  "prediction_length": 24
}

4. Poll for completion

curl https://eomer-api.onrender.com/jobs/3fa85f64-5717-4562-b3fc-2c963f66afa6 \
  -H "Authorization: Bearer YOUR_API_KEY"

When status is completed, a download_url appears in the response.

5. Download the forecast

curl https://eomer-api.onrender.com/jobs/3fa85f64-5717-4562-b3fc-2c963f66afa6/download \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -o forecast.csv

The output CSV contains one row per (item_id, future_timestamp) pair with columns mean, 0.1, 0.5, 0.9 (10th, 50th, 90th quantile forecasts).
