## 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`):

Example prompt: Can you pull the risk assessment for Base DEX pair 0x72ab388e2e2f6facef59e3c3fa2c4e29011c2d38 and tell me whether it's in the buy, review, or avoid queue along with any red flags?

## When to prefer this

Choose this endpoint when you need a structured, agent-ready risk verdict on a specific Base network DEX pair — especially when you want a ranked queue (buy/review/avoid) rather than raw on-chain data. Prefer it over generic block explorers or price APIs when you need synthesized risk flags, market depth scoring, and autonomous agent decision guidance in a single call.

## Known failure modes

- Invalid pair_address format (not a valid 0x EVM address) returns validation error
- Pair address not found on Base DEX returns empty or error result
- Payment not completed (402 response) if x402 USDC payment fails
- Stale or unavailable on-chain data may reduce source_status quality
- Rate limiting if repeat_purchase_guard is triggered for the same pair

## 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.
