How this service works
Pre-trade integrity gate for AI agents on prediction markets. ONE call returns ALLOW/WARN/BLOCK + risk_level 0-100 + sub-scores (market_integrity, liquidity, resolution, event_conflict) + risk_flags + ECDSA-signed evidence receipt. Supports Polymarket and Kalshi. Pattern-matches CFTC v. Van Dyke and Kalshi April 2026 disciplinary cases. The pre-trade question: is this market clean enough to touch?
Output
Returns a verdict (ALLOW/WARN/BLOCK), an overall risk_level from 0-100, four sub-scores (market_integrity, liquidity, resolution, event_conflict), a list of risk_flags identifying specific issues, and an ECDSA-signed evidence receipt suitable for audit trails. References pattern-matched regulatory cases including CFTC v. Van Dyke.
Example use cases
Pre-trade compliance check for automated agents
“My trading agent is about to execute a large position on a Kalshi contract about election outcomes. Run ToolOracle's integrity check on it and flag any regulatory red flags, liquidity concerns, or resolution risks before we commit capital.”
Signed audit trail for regulated fund trading
“We need a signed evidence receipt for every prediction market trade our fund executes on Polymarket. Before placing bets on upcoming economic indicators, check the market integrity and give us the risk breakdown so we can document our due diligence for auditors.”
Real-time manipulation detection for portfolio
“I want my agent to automatically screen all Kalshi contracts for market manipulation or integrity issues before considering them. Give me the ALLOW or WARN verdict with the specific risk flags so we can skip any suspicious markets and stick to clean trading opportunities.”
Technical details
Endpoint
POSThttps://tooloracle.io/v2/integrity_gateWhen to prefer
Use this endpoint when an AI agent is about to execute or recommend a trade on Polymarket or Kalshi and needs a single authoritative pre-trade gate with a signed audit trail. Prefer this over generic market data APIs when regulatory compliance, CFTC rule pattern-matching, or downstream audit requirements matter. Ideal when the agent must justify its trading decision or when risk sub-scores (liquidity, resolution, event conflict) are needed separately.
Side effects
- Unsupported platform submitted (not Polymarket or Kalshi) — returns error or BLOCK
- Market ID not found or expired — returns error with no verdict
- Payment not included or insufficient USDC — 402 Payment Required
- Malformed request body — 400 Bad Request
- ECDSA signing service temporarily unavailable — receipt may be absent
- Rate limit exceeded — 429 Too Many Requests
