x402 APIFailing, checked 7 h ago

Daily MVRV ratio (market cap / realized cap) for BTC or ETH from CoinMetrics' free community data, with the latest value, the window mean and standard deviation, and its z-score. Labels are plain statistics (HIGH_Z, LOW_Z, MID), not buy or sell calls. Realized cap in USD is not in the free tier, so only the ratio is returned.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.fadeandco.workers.dev/api/agent-intel/onchain-mvrv-valuation?asset=btc&days=365'

# 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 - 'https://api.fadeandco.workers.dev/api/agent-intel/onchain-mvrv-valuation?asset=btc&days=365' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
