## 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 blockchain-money-map-agent-spend-category-classifier-f51e8132 -d '<json body>'
```

Example prompt: Classify this agent payment for me: it was $0.05 USDC on Base network, paid to seller 'WeatherAPI Pro' for tool 'weather-forecast-v2' described as 'real-time weather data lookup' — what spending category does this fall into?

## When to prefer this

Use this endpoint when an AI agent needs to automatically categorize its own on-chain payments for expense tracking, policy enforcement, or audit trails — especially within x402 micropayment ecosystems on EVM-compatible networks. Prefer this over manual classification when you have structured transaction facts (seller, tool, amount, currency, network) and need a deterministic, low-cost label at $0.01 USDC per call.

## Known failure modes

- Missing required fields (seller_label, tool_id, description, amount, currency, or network) returns a validation error
- Ambiguous or generic description may yield a low-confidence or fallback category
- Payment on an unsupported or unrecognized network may reduce classification accuracy
- Malformed input schema causes a 400-level error
- x402 payment not included or invalid results in 402 Payment Required response before classification occurs
