# AgentDiet MPP Verifier

> AgentDiet MPP Verifier is a paid API for AI agents from status.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Verifies and validates MPP (Micropayment Protocol) compliance and context compression ROI for a given HTTP URL, returning compression ratio proof and status.

## Facts

- Endpoint: GET https://status.agentdiet.dev/v1/mpp-verifier?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-mpp-verifier-b9b4a951
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_0Yguarea3CkBBfXpBCz2S

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-mpp-verifier-b9b4a951
```

Example prompt: Can you verify whether this URL is MPP-compliant and show me the compression ratio proof AgentDiet can achieve on it: https://api.example.com/data?

## When to prefer this

Use this endpoint when you need to verify MPP protocol compliance or measure the token compression ROI that AgentDiet can deliver for a specific HTTP URL before committing it to an agent pipeline. Prefer it over generic HTTP probing tools when you need compression ratio metrics and A2A context distillation validation specifically within the AgentDiet ecosystem.

## Known failure modes

- URL parameter missing or malformed — endpoint may return error or empty data
- Target URL is unreachable or returns non-200 — verification may fail with error status
- Unsupported HTTP method specified — only GET and POST are accepted
- Payment not settled in USDC on Base — x402 micropayment failure blocks the call
- Response schema mismatch if target endpoint returns unexpected content type

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'status' field (e.g. 'ok'), a 'data' object with endpoint-specific details, and an 'roi_proof' object containing 'compression_ratio_pct' — a numeric percentage indicating how much the context can be compressed (e.g. 91.4%).
