## 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 diamond-bitcoin-whale-report-daily-large-transaction-feed-441fc6f1
```

Example prompt: Pull the Diamond whale report for 2025-01-20 so I can see which large Bitcoin transactions happened that day and their AML risk scores.

## When to prefer this

Choose this endpoint when you need a bulk, daily snapshot of all large Bitcoin transactions with AML risk metadata for a specific historical date. It is ideal for compliance analysts, blockchain researchers, or automated AML pipelines that need to ingest and screen high-value BTC flows day by day. Prefer it over per-address risk endpoints when you want broad market-level whale visibility rather than a point lookup on a single address.

## Known failure modes

- Missing or malformed date parameter returns an error — date must be YYYY-MM-DD format
- Requesting a future date may return an empty dataset or error
- Very recent dates (today or yesterday) may be incomplete if the pipeline hasn't finalized
- Payment failure or insufficient USDC/Lightning balance prevents access
- Response is gzip-compressed — callers that don't decompress will receive unreadable binary data
- No data may be returned for dates before the service's data history begins

## How this service works

Bitcoin address risk checks (sanctions, ransomware, laundering patterns), address watch alerts, a live market pulse and a daily whale report. Pay per call with Lightning or USDC - no account.

## Output

A gzip-compressed JSON Lines file where each line is a JSON object representing one whale-sized Bitcoin transaction for the requested day, with fields: ts (timestamp), txid (transaction ID), btc (amount in BTC), usd (USD value at time of transaction), nin (number of inputs), nout (number of outputs), and aml (AML risk score or classification).
