# Public Signal Data

> Six pay-per-result data APIs on the Apify platform: Polymarket whale trades, wallet P&L, odds snapshots, ATS job postings, new business filings, and federal contract intelligence. Structured JSON for AI agents, trading systems, and sales teams.

All actors are published on the Apify Store under `splendorous_astrolabe_xs9` (https://apify.com/splendorous_astrolabe_xs9) and are pay-per-event: you pay per result record, with no subscription. Apify's free plan includes $5 of usage credit per month. Every actor is callable via REST (`run-sync-get-dataset-items`), the Apify Python/JS clients, and as an AI-agent tool through the Apify MCP server (https://mcp.apify.com/?actors=<actor-id>).

## Actors

- [Polymarket Whale Trades Tracker](https://publicsignaldata.com/actors/polymarket-whale-trades/): Every large trade on Polymarket above your USD threshold — wallet, side, price, size, market — plus per-wallet flow summaries. Pricing: Run started $0.05 (flat fee per run); Whale trade $0.002 (per large trade returned). A 24-hour scan at a $5k threshold typically returns 100–400 trades: about $0.25–$0.85 per run. Run it: https://apify.com/splendorous_astrolabe_xs9/polymarket-whale-trades
- [Polymarket Wallet P&L Analyzer](https://publicsignaldata.com/actors/polymarket-wallet-pnl/): Paste any wallet address, get its reconstructed trading record: realized P&L, win rate, per-market breakdown, hedging share — with honest coverage flags. Pricing: Wallet analyzed $0.35 (full tape reconstruction, resolution lookups, P&L report). Flat $0.35 per wallet analyzed — vetting a shortlist of 20 wallets costs $7. Run it: https://apify.com/splendorous_astrolabe_xs9/polymarket-wallet-pnl
- [Polymarket Odds Snapshot](https://publicsignaldata.com/actors/polymarket-odds-snapshot/): Structured odds, prices, volume and liquidity for exactly the markets you care about — with optional price history from the public CLOB.

A single-sponsor daily watch usually costs under $0.10/day; a broad oncology phase-2/3 watch runs $0.30–$1.50/day after a one-time ~$4–5 baseline.
