# OracleInsight Execution Preflight Safety Check

> OracleInsight Execution Preflight 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).

Returns an ALLOW/CAUTION/BLOCK decision on whether sufficient oracle data exists to safely execute a declared on-chain action (swap, borrow, lend, etc.) before committing to it.

## 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-execution-preflight-safety-check-6013ae8d
```

Example prompt: Before I execute a $5,000 swap from ETH to USDC on Monad mainnet (chain 143), run a preflight safety check to see if the oracle data is sufficient — use the Pyth fast path and let me know if it's ALLOW, CAUTION, or BLOCK.

## When to prefer this

Use this endpoint when an AI agent or automated trading system needs to gate a DeFi action on real-time oracle data quality before committing to execution — especially on Monad mainnet. Prefer it over generic price feeds when you need a structured ALLOW/CAUTION/BLOCK verdict rather than a raw price quote. Ideal for risk-averse execution pipelines where oracle manipulation or data gaps could cause financial harm.

## Known failure modes

- Missing required query parameters (asset, chainId, action, tradeAmountUsd) returns a validation error
- Unsupported action type outside the enum returns an error
- Chain ID not recognized or unsupported returns an error
- BLOCK result is still charged $0.02 USDC — payment is not refunded on BLOCK
- Single provider scope (e.g. only 'pyth') is insufficient for an ALLOW verdict on Monad
- Network or upstream oracle data unavailability may result in CAUTION or BLOCK

## How this service works

Execution preflight: a chain-neutral ALLOW/CAUTION/BLOCK data-sufficiency decision for one declared action. A complete BLOCK result is charged; settlement occurs only after a successful response.

## Output

A verdict of ALLOW, CAUTION, or BLOCK indicating whether oracle data is sufficiently available and trustworthy to proceed with the declared on-chain action. The response reflects chain-neutral data-sufficiency assessment and may include context about which providers contributed to the decision.
