Whether the current reading is actually high or low, from a series captured every ~10 minutes: funding, open interest, Fear & Greed and BTC dominance, each as current, median, min, max and percentile over the window. A funding rate of 0.006% means nothing on its own; at the 89th percentile of the last 24 hours it means something. This is the question a snapshot endpoint cannot answer, whoever you buy it from.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.04.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://asistent-crypto.vercel.app/api/x402/data/market-history' \
  -H 'content-type: application/json' \
  --data-raw '{"hours":24}'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - -X POST 'https://asistent-crypto.vercel.app/api/x402/data/market-history' \
  -H 'content-type: application/json' \
  --data-raw '{"hours":24}' \
