Polymarket intelligence on x402. Real-time prediction-market signals across 42K markets: 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. Paid endpoints settle per call via x402 (USDC on Base) — no account, no API key.
Pay from $0.01 to $1.00 in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

All charts share the 7d window selected here. Every series is also served as JSON at /api/v1/services/orcatrace/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted).
PRICE (captured 402, USD)
Median across 6 endpoints. Use the selector to isolate one.
SUB-SCORES (uptime + x402 compliance)
VOLUME (on-chain settlement, USD)
Shared payout address (2 other services). On-chain settlement on this address may include those services, so this reads as operator volume, not service-only.
DISTINCT BUYERS
Shared payout address (2 other services). Buyers on this address may include those of other services on the same address.
