Trackrecord Reproduce

by api.manylives.me in Onchain & crypto

x402 APIPassing, checked 49 min ago

Check that a strategy's computed results and its on-chain stamped calls are the same strategy: for each stamped period in a date range, the calls locked on the Base network beforehand, the calls recomputed from public data, whether they match, each instrument's start and end close, and the period's return recomputed from those prices. Strategy logic stays private.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.manylives.me/paid/trackrecord/reproduce?id=CRY-5m-005'

# 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.manylives.me/paid/trackrecord/reproduce?id=CRY-5m-005' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
