## 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 paddock-whale-activity-api-d6df6f89
```

Example prompt: Pull the Paddock whale activity data for the last 14 days, filtering to transactions of at least $500 USD, and show me how volume breaks down by category and facilitator.

## When to prefer this

Choose this endpoint when you need aggregated, large-transaction-focused market intelligence about AI agent payments — especially to identify which categories or facilitators are absorbing outsized spend. It is distinct from raw transaction feeds or per-domain lookups; use it for macro market analysis, concentration risk assessment, or trend monitoring at the whale tier.

## Known failure modes

- window parameter out of range (must be 1–90 days) returns 422 validation error
- min_usd below 0 returns validation error
- insufficient data for the selected window may return empty arrays
- payment failure or expired x402 token returns 402 Payment Required
- rate limiting may return 429 if called too frequently

## Output

A JSON object containing: total count and USD volume of large settlements, a breakdown by size band (e.g. $100k+), a breakdown by AI service category (e.g. LLM & inference), a breakdown by facilitator (e.g. Coinbase), the window in days, and the threshold used to define 'large' transactions.
