# ToolOracle Agent Pre-flight & Action Audit

> ToolOracle Agent Pre-flight & Action Audit is a paid API for AI agents from tooloracle.io, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Evaluates whether an AI agent should execute a given action by running a combined safety check (evidence freshness, provenance, policy, risk scoring, hallucination signals) and returning a GO/CAUTION/STOP/INSUFFICIENT_EVIDENCE verdict with a cryptographic receipt.

## Facts

- Endpoint: POST https://tooloracle.io/v2/agent_preflight
- Price: $0.005/call
- Payment: x402
- Status: unknown

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 tooloracle-io-0c3b039c -d '<json body>'
```

Example prompt: Before my agent sends that $500 USDC payment to vendor wallet 0xABC…, run a pre-flight safety check on the action — I need a GO/CAUTION/STOP verdict with evidence freshness, provenance trace, policy gate, and a cryptographic receipt I can use as compliance evidence.

## When to prefer this

Choose this endpoint when you need a single combined pre-flight gate for autonomous agent actions — especially for financial transactions, content publishing, regulatory submissions, or multi-step workflows where you require both a human-readable verdict and a cryptographic audit receipt. Prefer over building custom validation logic when you need provenance tracing and hallucination signal detection in one call.

## Known failure modes

- Insufficient context about proposed action returns INSUFFICIENT_EVIDENCE verdict
- Unknown agent or action type may trigger STOP as a safe default
- Stale or missing evidence sources lower confidence and may yield CAUTION
- Policy configuration mismatch causes blocking response
- Network timeout or service unavailability returns 5xx error with no receipt

## How this service works

AI agent decision pre-flight + action audit + autonomous safety — should agent X execute action Y? Combined check: evidence freshness, provenance trace, policy gate, risk scoring, hallucination signals. Returns GO / CAUTION / STOP / INSUFFICIENT_EVIDENCE with cryptographic receipt. For autonomous agent workflows: tool calls, financial transactions, content publishing, regulatory submissions, multi-step task execution, agent compliance evidence, MCP gateway routing.

## Output

Returns a structured verdict of GO, CAUTION, STOP, or INSUFFICIENT_EVIDENCE along with a risk score, evidence freshness rating, provenance trace, policy gate outcome, hallucination signal indicators, and a cryptographic receipt usable as an audit or compliance artifact.
