## 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-mint-authority-check-6bfc3ad7
```

Example prompt: Check the mint authority status for wallet address 0xABC123... on the AgentDiet rag-diet node — I want to confirm whether it's a recognized authority for USDC settlement on Base.

## When to prefer this

Use this endpoint when you need to programmatically verify whether a specific wallet address holds mint authority on the AgentDiet USDC/Base payment node, particularly before initiating A2A, MCP, or x402 payment flows. Prefer this over manual blockchain lookups when you need a fast, API-accessible authority check integrated into an agent workflow.

## Known failure modes

- Invalid or malformed wallet address returns an error status
- Address not found or not recognized as a mint authority returns empty data
- Missing required 'input' object in request body causes schema validation error
- Network or node unavailability may return non-200 response
- Payment not completed (x402 payment required before response is returned)

## How this service works

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

## Output

Returns a JSON object with a status field ('ok' or error), a data object containing authority details, and a roi_proof object showing a compression_ratio_pct (e.g. 91.4%) as proof of the node's distillation performance.
