## 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 draconic21-daily-agent-signal-latest-08b98b84
```

Example prompt: Fetch me the latest daily agent signal from draconic21 right now — pay the $0.03 USDC fee and return whatever signal payload comes back.

## When to prefer this

Use this endpoint when your AI agent needs a daily signal from draconic21 specifically, is funded with USDC on Base for x402 micropayments, and requires only the current day's signal rather than historical depth. Prefer this over /v1/signal_history or /v1/signal_delta when you only need the freshest signal at the lowest per-call cost ($0.03 vs $0.10/$0.05).

## Known failure modes

- HTTP 402 returned when no valid x402 payment header is included or payment fails — agent must fund wallet and retry
- Empty or minimal archive depth: only one day of seed data (2026-09-19), so historical context is extremely limited
- Service hosted on Render free tier may experience cold-start latency or downtime
- Malformed request body returns 4xx error
- No multi-day archive depth currently available despite history/delta routes being wired
