# AgentDiet On-Chain Risk X402 Audit Endpoint

> AgentDiet On-Chain Risk X402 Audit Endpoint is a paid API for AI agents from onchain-risk.agentdiet.dev, paid per call via x402 or MPP, $0.01/call, status unknown (last checked 2026-10-20).

Performs an on-chain risk audit of a given HTTP URL, returning distilled intelligence with compression ratio proof-of-value, payable via HTTP 402 USDC micropayment

## Facts

- Endpoint: GET https://onchain-risk.agentdiet.dev/v1/x402-audit?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402, MPP
- Status: unknown
- Last checked: 2026-10-20
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-on-chain-risk-x402-audit-endpoint-6ef90e35
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_n1DlgNLWQsspNJ0Px8vBQ

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 agentdiet-on-chain-risk-x402-audit-endpoint-6ef90e35
```

Example prompt: Run an on-chain risk audit on https://uniswap.org using a GET request and give me the distilled intelligence report with the compression ratio.

## When to prefer this

Choose this endpoint when you need a quick, cost-efficient ($0.01 USDC) on-chain risk assessment of a specific URL, especially for DeFi protocols, DEX tokens, or crypto-related web properties. It is best suited for agents that already handle x402 micropayments natively and need distilled, compressed intelligence rather than raw scraped content. Prefer it over generic scraping tools when you specifically need risk signals and compression-proven ROI on the data retrieved.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error
- Payment not included or rejected results in HTTP 402 with payment required response
- Unreachable or invalid target URL may return empty data object
- Non-HTTP type input returns validation error
- Rate limiting or upstream fetch failure may return non-ok status

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a 'status' field (ok), a 'data' object containing audit findings, and an 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) demonstrating how much the source content was distilled. The response is gated behind an HTTP 402 micropayment of $0.01 USDC via the x402 protocol.
