## 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 keelbase-signal-daily-latest-26bc35bc
```

Example prompt: Can you pull the latest Keelbase Signal daily report for me — I want the full records, the synthesis, and any warnings about data completeness?

## When to prefer this

Use this endpoint when you need the most current Keelbase Signal daily publication without specifying a date — it always returns the latest available record set. Prefer this over date-specific endpoints when you want the freshest data automatically. Ideal for daily briefing pipelines, monitoring workflows, or any agent task requiring up-to-date Keelbase Signal intelligence.

## Known failure modes

- No latest publication available — endpoint may return empty or placeholder fixture data
- Payment not processed (x402 protocol) — call rejected without valid $0.03 USDC payment
- Rate limiting or quota exceeded — returns 429 or similar error
- Incomplete data — completeness metadata may indicate partial records with warnings
- Network timeout if synthesis generation is slow
