# Augur Risk - Base Contract Admission Control

> Augur Risk - Base Contract Admission Control is a paid API for AI agents from augurrisk.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Analyzes a Base smart contract address and returns a risk decision, policy recommendation, and supporting findings to gate agent transactions before execution.

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 augur-f005c157
```

Example prompt: Before my agent approves and routes funds through this Base contract at 0x1234...abcd, run an Augur risk analysis on it and tell me the decision and policy recommendation — flag any suspicious findings.

## When to prefer this

Use this endpoint as a pre-flight gate before any AI agent action involving a Base smart contract — buying tokens, routing funds, approving spending, or calling contract methods. Prefer this over generic security scanners when you specifically need a structured admit/deny decision with a policy recommendation optimized for autonomous agent workflows on Base, payable per-call via x402 USDC with no subscription required.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract not deployed on Base network returns not-found or unsupported error
- Payment via x402 fails or is insufficient, returning a payment-required error
- Timeout if contract bytecode analysis takes too long
- Rate limiting if too many calls are made in quick succession

## How this service works

Deterministic Base contract admission control for agents on Base. Analyzes bytecode patterns (proxy detection, reentrancy, selfdestruct, honeypot, hidden mint, fee manipulation, delegatecall, deployer reputation) and returns a default decision, policy recommendation, supporting findings, and a composite 0-100 score. "safe" is not a guarantee or audit. Pay $0.10/call via x402 in USDC on Base.

## Output

Returns a default risk decision (allow/deny or similar verdict), a policy recommendation advising whether the agent should proceed, and supporting findings that detail the specific risk signals or indicators detected for the given contract.
