## 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 ragradar-transaction-history-by-chain-and-address-ec7430d4
```

Example prompt: Pull the full transaction history for wallet address 0xAbC123...on Base using RagRadar so I can see everything this address has done on-chain.

## When to prefer this

Use this endpoint when you need historical transaction records for a specific wallet address on Base, Arbitrum, or Solana. Prefer this over general blockchain explorers when you need structured, AI-ready JSON output and are already using RagRadar's multi-chain analytics suite.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unsupported chain identifier results in a 400 or 404 response
- Address with no history may return empty results
- Payment not processed (x402 payment required) results in 402 response
- Rate limiting or service downtime returns 5xx errors
