# OracleInsight Swap Intent Safety Check

> OracleInsight Swap Intent Safety Check is a paid API for AI agents from www.oracleinsight.xyz, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Runs a two-gate pre-trade safety check on a same-chain swap intent and returns a signed ALLOW/CAUTION/BLOCK verdict with EIP-712 attestations

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability oracleinsight-swap-intent-safety-check-4acb3a0e
```

Example prompt: Before I execute this swap, run an OracleInsight pre-trade safety check on selling 5 ETH for USDC on chain ID 1 with a declared notional of $12000 — I need the signed ALLOW/CAUTION/BLOCK verdict before we proceed.

## When to prefer this

Choose this endpoint when an AI agent or automated trading system needs a cryptographically verifiable, signed pre-trade safety gate before executing a same-chain swap — especially when oracle manipulation risk is a concern and downstream systems require EIP-712 attested proof of the safety decision. Prefer this over generic price-check APIs when you need an auditable ALLOW/CAUTION/BLOCK verdict that can be verified on-chain.

## Known failure modes

- Missing required query parameters (sourceAsset, destinationAsset, subjectChainId, settlementChainId, declaredNotionalUsd) returns 400
- settlementChainId not equal to subjectChainId returns validation error in v1
- Payment not received or x402 settlement failure blocks the response
- Invalid or unsupported chainId returns an error
- Declared notional of zero or negative value may be rejected

## How this service works

Verified Swap Intent: two signed schema-v3 Pre-Trade gates for one same-chain swap, plus one Execution Receipt credit after x402 settlement. A BLOCK is a complete, charged decision.

## Output

Returns two signed schema-v3 Pre-Trade gate attestations (EIP-712) and one Execution Receipt credit, together constituting a complete ALLOW/CAUTION/BLOCK decision block for the queried same-chain swap intent. The verdict indicates whether the swap should proceed, requires caution, or should be blocked based on oracle integrity and risk signals.
