## 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 sec-fails-to-deliver-data-144d4b4e -d '<json body>'
```

Example prompt: Pull the latest SEC fails-to-deliver data for TSLA — show me up to 50 records with settlement dates, quantities, and values.

## When to prefer this

Use this endpoint when you need official SEC-sourced fails-to-deliver data for equities — particularly for short-squeeze analysis, settlement risk assessment, or regulatory research. Prefer this over generic financial data APIs when you specifically need the EDGAR CNS fails dataset with CUSIP-level detail and official settlement dates.

## Known failure modes

- Symbol not found or no FTD records — returns empty fails array
- Invalid limit value outside 1-100 range — likely returns validation error
- SEC data publication delay of ~2 weeks means very recent settlement failures will not appear
- Temporary upstream unavailability of SEC EDGAR source data
