Extract parquet data

Use the data export endpoints to fetch presigned download URLs, then download and query the files locally.

Supported datasets

curl -s -H "X-API-Key: $API_KEY" \
  "https://api.delphiterminal.co/api/v1/data/rfqs?date=2026-02-13" \
  > export.json

This response includes parts, where each part contains a temporary presigned url.

URL=$(jq -r '.parts[0].url' export.json)
echo "$URL"

curl -L "$URL" -o rfqs_2026-02-13.parquet

Presigned URLs expire quickly (typically 5 minutes). If the download fails, request fresh metadata and retry.

duckdb -c "SELECT * FROM read_parquet('rfqs_2026-02-13.parquet') LIMIT 20;"

import polars as pl

df = pl.read_parquet("rfqs_2026-02-13.parquet")
print(df.head())
print(df.shape)

To fetch today’s dataset without passing a date:

curl -s -H "X-API-Key: $API_KEY" \
