Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agent-bounty-radar-base-usdc-health-check-0c6c7865
```

Example prompt: Can you check if the Base network and USDC contract are healthy right now — I need to know the latest block, current gas price, and whether the seller payout rail is ready before I send a payment?

## When to prefer this

Choose this endpoint when you need a quick, live snapshot of Base network health and USDC contract readiness before executing or routing x402 micropayments on Base. It is especially useful as a pre-flight check in agentic payment workflows to confirm infrastructure is operational before committing funds.

## Known failure modes

- HTTP 402 returned if the $0.01 USDC x402 payment header is missing or invalid — agent must retry with valid payment
- Network timeout if Base RPC is temporarily unavailable
- Stale block data if the underlying Base node is syncing
- Zero values for gas_price_wei/gwei if the node cannot fetch current fee data

## How this service works

Two fixed-price x402 v2 APIs on Base. Unpaid requests return HTTP 402 with PAYMENT-REQUIRED; paid retries return JSON and PAYMENT-RESPONSE.

## Output

A JSON object containing: Base network metadata (name, chain_id 8453, latest_block, gas_price_wei, gas_price_gwei), native USDC contract details (address, decimals, contract_deployed boolean), and seller rail info (status string, payout_address, current_usdc_balance in USDC).
