## 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 api-cryptoetfsentinel-com-7dcbf31f
```

Example prompt: Pull the latest profiles for every trading US spot crypto ETF — I need custodian, sponsor fee, authorized participants, basket size, and in-kind eligibility for all of them at once.

## When to prefer this

Use this endpoint when you need a complete, up-to-date snapshot of all trading US spot crypto ETFs in a single call rather than querying issuers one by one. Ideal for bulk analysis, comparison tables, or building a comprehensive dataset of ETF structures. Prefer this over single-issuer endpoints when you don't know which CIKs to query or need the full market view at once.

## Known failure modes

- Payment required (402) if x402 USDC payment of $0.50 is not included
- Partial or missing field data where POS AM extraction confidence is low (especially in-kind eligibility ~32% TP)
- Stale profiles if POS AM filings have not been re-processed recently
- Empty or reduced result set if no ETFs are currently in trading status
