free tier
Free keys can test the moat.
Free access includes authenticated calls to dispute lifecycle, resolution-risk and action-aware preflight diagnostics inside quota. This is enough to verify that the API returns useful stop/go objects instead of generic market data.
GET /v1/dispute/polymarket/580810Known disputed UMA history should return DO_NOT_ACT with UMA_DISPUTE_DETECTED.
GET /v1/resolution-risk/polymarket/580810Shows resolution ambiguity and dispute-risk evidence.
GET /v1/preflight/...notional_usd=...Checks public book capacity against the requested action.
builder plan
30 EUR/month for recurring agent operations.
Paid access unlocks the parts that matter once an agent runs continuously: customer watchlists, webhook delivery, alert reconciliation, signed receipts, higher quota, account-managed key rotation and Stripe billing from the account console.
Buy only if the recurring layer matters. If you only need a one-time manual lookup, the free tier and public sources may be enough.
Run the 5-minute test, then create account and upgrade from the account console.
machine payment
x402 is available for agents that pay per call.
The canonical route is /x402/v1/dispute/{venue}/{market_id}. It accepts standard x402 payment retries and a Polygon USDC transaction-hash bridge for agents that can pay on-chain but cannot yet construct a standard payload.
Account/API-key/Stripe remains the main path. x402 is a machine-call path, not a replacement for the account console.
boundaries
Diagnostics only.
Do Not Act does not custody funds, hold private keys, sign orders, route execution, submit orders, promise performance, or turn missing evidence into confidence.
