## How to call it through Zero

```sh
zero fetch --capability dripstack-stock-picks-api-1230be4f
```

Example prompt: Pull me the stock-picker calls that DripStack extracted from Substack newsletters for January 15, 2025 — give me up to 50 results.

## When to prefer this

Use this endpoint when you need structured, AI-extracted stock recommendation data sourced specifically from Substack newsletter publications, with attribution to original posts. Prefer this over generic financial data APIs when you want curated, human-authored newsletter-sourced picks rather than raw market data or analyst ratings.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns a 400 or validation error
- Limit out of range (below 1 or above 500) returns a validation error
- No picks available for the requested date returns an empty items array with count 0
- Payment failure via x402 protocol blocks the response
- Date in the future may return empty or no data

## How this service works

Connect your agent to top financial newsletters and podcasts.

## Output

A JSON object containing a date range (startDate, endDate), an asOf timestamp, a count of results, and an array of stock-pick items extracted from distinct attributed Substack source posts. Payment is charged per distinct source post returned, minimum $0.10 USD.
