## 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 coinopselect-reserves-classify-api-f274bc0f
```

Example prompt: Can you classify the reserves for this contract using a drift of 50 basis points and tell me what category they fall into?

## When to prefer this

Choose this endpoint when you need to classify on-chain reserve data by drift tolerance (in basis points) and receive a structured categorization — particularly useful for DeFi risk assessment, stablecoin monitoring, or pre-trade checks on the Base network. Prefer it over raw blockchain queries when you need a pre-built classification layer rather than raw reserve figures.

## Known failure modes

- Missing required 'drift' query parameter returns a validation error
- Invalid 'type' or 'method' fields may return empty or malformed classification
- Payment not fulfilled (402) if x402 USDC payment on Base is not provided
- Network or provider downtime may return 5xx errors
- Drift value out of expected range may yield an empty classification object

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object with a 'query' field set to 'reserves-classify' and a 'classification' object containing the categorized reserve assessment based on the provided drift parameter.
