## 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 batch-variant-market-snapshots-tokens-api-base-evm-eb6f70c6 -d '<json body>'
```

Example prompt: Can you pull batch market snapshots for the token variants I'm tracking on Base — I need current price, liquidity, and market metrics for all of them in one shot?

## When to prefer this

Use this endpoint when you need to retrieve market data for multiple token variants in a single efficient batch call on the Base/EVM network, rather than making individual requests per token. Prefer this over single-token market endpoints when you need to compare or aggregate data across several variants simultaneously.

## Known failure modes

- Empty or malformed body results in schema validation error
- Token variants not found on Base network return empty or null snapshot entries
- Payment not completed (x402) results in 402 Payment Required response
- Rate limiting may apply if too many variants are batched
- Network or RPC errors for Base chain may return partial or failed snapshots
