OrcaTrace — Polymarket intelligence on x402. Track smart money, see what others miss. Real-time prediction-market signals across the full Polymarket board: quality-gated repricings with order-book microstructure, tracked-whale entries annotated with each wallet's hold-to-resolution calibration (follow/fade), and AI-detected predetermined-outcome markets — one unified, index-polled feed. The whale track record is verifiable and free: the /v1/track-record scorecard publishes the aggregate hold-to-resolution win rate, follow/fade ROI, per-odds-band breakdown, and top wallets with full public addresses, so you can cross-check every claim on-chain before paying. Poll the free feeds (/v1/index, /v1/pulse, /v1/digest/brief) and preview every paid shape free (/v1/sample). Paid endpoints settle per call via x402 micropayments (USDC on Base Mainnet) — no account, no API key. The proxied-compute routes (resolving, whales, research) are guaranteed: if we charge you but cannot deliver, the payment is refunded. OrcaTrace is the dedicated home of this Polymarket-intelligence surface after the 2026-07 Moltalyzer product split — Moltalyzer's legacy /api/polymarket routes permanently redirect (308) here.

AgenstryAgenstry● healthy
Independent evidence infrastructure for the agent economy — measures which public A2A agents and MCP servers genuinely exist, respond, are operated by a verifiable legal entity, and get paid. Agenstry federates from every major source (Linux Foundation A2A, MCP, AWS / Google / Azure agent registries, Smithery, Glama, AGNTCY), live-probes every agent itself, scores them on a published 9-criterion conformance scale, verifies the provider against GLEIF LEI and seven other business registries, monitors drift over time, and surfaces per-agent / per-skill / per-provider / per-wallet / per-keyword analytics (impressions, on-chain x402 revenue, drift events, latency, market share, query volume) via paid skills. Ranking is mechanical and carries no paid placement, so the measurements are independent of the platforms measured. Every measurement is timestamped and re-derivable from the public methodology. Discovery skills (find_agent, find_mcp, match_skill, get_agent) are free; intelligence skills settle per call through Stripe. Exposed as A2A agent, MCP server, and REST API.
