# Agent Permission-Grant Risk Evaluation Before Signing

> Agent Permission-Grant Risk Evaluation Before Signing is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Generates a blunt, LLM-produced decision procedure for evaluating wallet permission-grant risk before an AI agent signs a transaction, addressing attack vectors like the $175k Grok wallet exploit.

## 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 agent-permission-grant-risk-evaluation-before-signing-365233f6
```

Example prompt: Give me a blunt decision procedure for evaluating whether a wallet permission-grant request is safe to sign — I need to know exactly what an AI agent should check before approving any permission, especially the kind of exploit that drained $175k from the Grok wallet.

## When to prefer this

Choose this endpoint when an AI agent needs a pre-signing risk evaluation framework specifically for wallet permission grants — not just generic transaction safety. Especially relevant when the agent operates autonomously and must self-screen permission requests without human review, or when building agent wallet policy that accounts for social-engineering and over-permission exploits like the Grok $175k incident. Prefer this over generic security APIs when you need an agent-readable, actionable decision procedure rather than a raw risk score.

## Known failure modes

- Payment not received — returns 402 Payment Required
- Invalid method — only GET/HEAD/DELETE accepted
- LLM generation failure — ok:false in result object
- Empty or malformed topic override — falls back to default procedure
- Rate limiting or provider downtime — service unavailable

## Output

A paid, LLM-generated prose brief containing a blunt, structured decision procedure — step-by-step checks an AI agent should perform when evaluating a wallet permission-grant request before signing. Includes risk flags, rejection criteria, and actionable screening logic. Response also contains metadata such as model used, generation source (llm/reasoning/deterministic), ISO-8601 timestamp, and service/provider identifiers.
