## 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-x402-buyer-market-scout-59fe590e
```

Example prompt: Search x402 services for Bitcoin 15-minute up/down prediction-market microstructure data on Base mainnet, budget up to $0.05, show me the top 5 results including your own catalog so I know the best route to purchase.

## When to prefer this

Use this endpoint when an autonomous agent needs to discover and compare x402-protocol paid data services before committing to a purchase — especially for Base token risk, DeFi wallet data, or Bitcoin 15-minute prediction-market feeds. Prefer this over direct endpoint calls when the agent does not yet know which specific x402 service to use and needs a ranked shortlist with purchase strategy.

## Known failure modes

- No matching services found for the given buyer_task — returns empty shortlist with market_gap explanation
- Network filter yields no results — try broader CAIP-2 or omit network param
- max_price_usdc too low — all found services flagged as over-budget, no viable route returned
- External Bazaar search timeout — service_search_verdict indicates partial results from own catalog only
- Invalid limit value outside 2-10 range — 400 validation error

## 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 object with a buyer shortlist, service comparison matrix, purchase strategy, priority queue, risk breakdown, next recommended paid API call, capability-to-purchase mapping, market gap analysis, and source status — giving an agent everything needed to choose and execute the optimal x402 data purchase.
