## 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-buyer-radar-c663afd4 -d '<json body>'
```

Example prompt: Pull the buyer radar signal for the electric vehicle accessory market and tell me which brands and products are seeing the most active purchasing intent right now.

## When to prefer this

Use this endpoint when you need to detect active buyer intent or purchasing demand signals for specific brands or products, particularly in an autonomous agent workflow that pays per call via USDC on Base. Prefer /v1/buyer_radar at $0.08 over the signal_latest ($0.03) when buyer-specific radar intelligence (rather than general daily signal) is required.

## Known failure modes

- HTTP 402 returned if payment not provided or insufficient USDC balance
- Empty or null signal if no buyer activity detected for the given input
- Malformed request body returns 400-level error
- Service unavailability on Render cold-start may cause timeout
- Single-day archive depth (2026-09-19) means historical comparisons are not yet meaningful

## How this service works

GO-TO product for funded agents: Daily Agent Signal (POST /v1/signal_latest $0.03, /v1/signal_history $0.10, /v1/signal_delta $0.05). Signal is the flagship; supporting/legacy routes are demoted. Archive honesty: archive_day_count=6 — 6 stored dates from 2026-09-19 through 2026-09-27. Intraday revisions do not add archive days. Unpaid calls return HTTP 402. USDC on Base. Free discovery: /, /agents.md, /llms.txt, /skill.md, /.well-known/x402.json, /.well-known/mcp.json, /openapi.json.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'brand' string identifying the brand with buyer activity, and a 'product' string identifying the product generating the signal, along with any additional radar metadata in the response body.
