What I build

Lightweight data Actors for crypto and prediction market analytics. Every Actor follows the same rules:

  • Public endpoints only — no logins, no API keys, nothing stored.
  • Normalized output — venues use different raw conventions; I convert them so the numbers are directly comparable.
  • Stable JSON schema — safe to wire into dashboards, alerts, spreadsheets, or AI agents via MCP.
  • Fast and cheap — runs finish in a few seconds at 256 MB, so pay-per-event pricing stays honest.

Actors

  • Perp Funding Rate Snapshot — every liquid perpetual's funding rate on Hyperliquid + Kraken Futures, annualized, with volume, open interest, pay direction, and cross-venue spreads. For funding-carry screening.
  • Stablecoin Peg Monitor — live on-chain peg deviations (bp) read straight from Uniswap-v3-style pools, with liquidity, tick, and a dislocation flag. Ships with the Polygon USDC.e/USDC/USDT pools behind Polymarket's pUSD plus pUSD supply; add any pool on Polygon, Base, Ethereum, or Arbitrum. Schedule it with onlyDislocated for alerts.
  • DEX Pool APR Ranker — concentrated-liquidity pools (Aerodrome, Uniswap v3/v4, PancakeSwap, Velodrome…) on any chain, ranked by fee APR, momentum, fee velocity, and a risk-gated heat score, with stable/volatile classification and plain English risk tags. For LP screening.

Support

Open an issue on the Actor page and I'll fix upstream API changes promptly. Raw values are always returned alongside the normalized ones, so you can apply your own conventions.
