## 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 radhikachain-web-wallet-endpoint-x402-1c247a02
```

Example prompt: Pull the latest chain telemetry and verifiable computation data from RadhikaChain — I want ZK proof stats (Halo2/Nova/Plonky3) and defense intelligence, and I'm fine paying $0.165 USDC per request on Base with no subscription needed.

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-request access to blockchain telemetry, ZK proof computation results, or chain defense intelligence without committing to a subscription or account. Especially suited for agents that need occasional or sporadic chain data on Base and can pay $0.165 USDC per call via the x402 micropayment protocol.

## Known failure modes

- Payment not included or malformed x402 header → 402 Payment Required
- Insufficient USDC balance on Base → payment rejected, no data returned
- Invalid or expired payment token → authentication failure
- Endpoint returns empty or partial data if telemetry feed is temporarily unavailable
- Rate limiting if too many requests submitted in short succession
