## 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 xx402-top-service-opportunity-radar-20c1d523
```

Example prompt: Scan the x402 ecosystem for the top service-building opportunities targeting autonomous buyer agents — sample up to 500 CDP resources and 200 x402scan sellers, and include the avoid list so I know what niches to steer clear of.

## When to prefer this

Use this endpoint when you need a strategic market radar across the full x402 ecosystem — combining CDP, Onyx Bazaar, and x402scan signals — rather than raw on-chain data or single-source seller rankings. It is especially valuable for x402 data sellers deciding what to build next or for autonomous agents evaluating the landscape of available data products.

## Known failure modes

- CDP or x402scan APIs return partial data if limits are too high, resulting in incomplete opportunity rankings
- Source status may report degraded upstream feeds from x402scan or Onyx Bazaar
- If buyer_segment is too narrowly specified, recommended builds may be irrelevant to actual market demand
- Payment failure via x402 ($0.01 USDC) results in 402 response before any data is returned
- Opportunity data may be stale if underlying bazaar indices have not refreshed recently

## How this service works

Paid Base token, wallet, DeFi, chain-read, x402 buyer/seller discovery, and specialized Bitcoin 15-minute Up/Down prediction-market data packets for autonomous agents and risk tools.

## Output

Returns a structured JSON report including: a summary and opportunity decision, a ranked priority queue of recommended builds, risk breakdown by category, review and avoid queues, bucket counts, next product suggestions, category demand rankings, top domains and resources, recommended builds, our position assessment, and source status from CDP, Onyx, and x402scan APIs.
