# AgentDiet x402 Audit Endpoint

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

Audits a given HTTP URL by fetching and distilling its content, returning structured data with a compression ratio proof via x402 micropayment

## Facts

- Endpoint: GET https://polymarket-odds.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-x402-audit-endpoint-f72e50ee
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_f7WK_95Ma6mceGMRfnEZf

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-x402-audit-endpoint-f72e50ee
```

Example prompt: Can you audit this URL for me — https://example.com/somepage — using a GET request and give me the distilled content along with the compression ratio?

## When to prefer this

Choose this endpoint when you need to fetch, distill, and compress a web URL's content into structured machine-readable data and want a quantitative compression/ROI proof alongside the result. It is especially useful for agent pipelines that need to reduce large web pages to compact summaries before further processing, and when you want to pay per-call via x402 USDC micropayments rather than a subscription.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Missing required 'input' object causes schema validation failure
- Unsupported HTTP method (not GET or POST) returns an enum validation error
- Target URL returns non-200 response, potentially causing empty or error data
- Payment failure via x402 prevents the request from being processed

## 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

A JSON object with a 'status' field ('ok'), a 'data' object containing distilled content extracted from the target URL, and an 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) indicating how much the content was compressed relative to the original.
