FinSight
A paid financial portfolio analytics API for AI agents, built on MPP (Machine Payments Protocol). Agents send portfolio data and pay micro-amounts in USDC per request to receive risk metrics, rebalance suggestions, diversification scores, and stress test simulations.
Quick Start
Make sure you have an mppx account set up:
npx mppx account create
npx mppx account view --show-key
Then call any endpoint directly:
npx mppx https://finsight-mpp.YOUR-SUBDOMAIN.workers.dev/analyze/risk \
--method POST \
--body '{"holdings":[{"asset":"ETH","weight":0.5},{"asset":"BTC","weight":0.3},{"asset":"USDC","weight":0.2,"isStable":true}]}'
