# AgentDiet x402 Audit Endpoint

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

Performs an HTTP-based audit or distillation analysis on a given URL, returning compressed intelligence data with a compression ratio proof, paid via x402/USDC microtransaction

## Facts

- Endpoint: GET https://mcp-compiler.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-4132b88d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_p00ZIFTNL4RWtNBBnukeX

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-4132b88d
```

Example prompt: Can you run an x402 audit on https://example.com and pull back the distilled intelligence summary with the compression ratio proof?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call ($0.01 USDC) web distillation or audit of a URL with a quantified compression ratio proof. It is ideal for agents that need to process many URLs cheaply via micropayments (x402/Base USDC) without a subscription. Prefer it over full crawlers when you want compressed intelligence rather than raw HTML, and when you need ROI-provable data reduction.

## Known failure modes

- Missing or invalid 'url' query parameter returns an error or empty data object
- URL is unreachable or returns non-200 — audit may return empty data or error status
- Payment failure via x402/USDC causes HTTP 402 response before audit executes
- Malformed input schema (missing required 'type' or 'method' fields) returns validation error
- Rate limiting or quota exceeded may return error 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 'data' field containing the distilled audit output, a 'status' field (e.g. 'ok'), and an 'roi_proof' object containing a 'compression_ratio_pct' value indicating how much the source content was compressed (e.g. 91.4%).
