Triggers Custom

by CRYPTYX in Onchain & crypto

x402 APIPassing, checked 2 h ago

Arbitrary trigger definition — POST any {type: z_score|z_differential|composite, ...} predicate and get the full institutional evidence envelope back. 5-year backtest, Sortino, max drawdown, profit factor, walk-forward IS/OOS, regime context, rolling hit rates. Enterprise tier because every request runs a live backtest (no cache). The extensibility endpoint: anything expressible in Metric Slicer becomes a triggerable institutional-grade primitive. Backtests run over the CRYPTYX 200+ tracked digital assets — BTC, ETH, SOL, top-cap + long-tail coverage.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.25.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://cryptyx.ai/api/triggers/custom' \
  -H 'content-type: application/json' \
  --data-raw '{"asset":"","definition":{},"horizon":""}'

# 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://cryptyx.ai/api/triggers/custom' \
  -H 'content-type: application/json' \
  --data-raw '{"asset":"","definition":{},"horizon":""}' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
