# AgentDiet x402 Compliance Status Check

> AgentDiet x402 Compliance Status Check 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).

Returns the x402 compliance status and context compression proof-of-ROI for the AgentDiet distillation node

## Facts

- Endpoint: GET https://status.agentdiet.dev/v1/402-compliance?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22

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-compliance-status-check-b0e0b2f3
```

Example prompt: Check whether the AgentDiet context distiller node is x402-compliant and show me the latest compression ratio it achieved — I want to confirm it's actually delivering the promised token savings before I route traffic through it.

## When to prefer this

Choose this endpoint when you need to verify that the AgentDiet x402-compliant node is operational and confirm its current context compression performance metrics before routing A2A or MCP agent traffic through it. Prefer this over generic health checks when you specifically need the roi_proof compression_ratio_pct as evidence of token efficiency, or when auditing 402-compliance of the distillation node settling in USDC on Base.

## Known failure modes

- Payment not settled in USDC on Base — node returns 402 with payment required
- Node offline or unreachable — connection timeout or 503 response
- Invalid input schema — missing required 'type' or 'method' fields returns validation error
- Stale or cached compression metrics if node is degraded
- Query parameter 'url' malformed — may return empty or error data object

## 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 node details, and an 'roi_proof' object containing 'compression_ratio_pct' indicating the percentage of token reduction achieved (e.g. 91.4%). Used to confirm the node is operational and delivering on its compression guarantees.
