## 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 zerion-api-wallet-transactions-c50b6792
```

Example prompt: Pull the full transaction history for wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e across all chains using Zerion.

## When to prefer this

Choose this endpoint when you need interpreted, human-readable transaction history for a wallet across 40+ EVM chains and Solana in a single call — especially useful for agents that pay per call via x402 and need structured JSON:API output without managing their own indexing infrastructure. Prefer this over raw RPC node calls when you want enriched, decoded transaction data rather than raw hex.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Non-existent or empty wallet returns an empty data array
- Payment not attached or insufficient USDC balance returns 402 Payment Required
- Rate limiting or quota exceeded returns 429
- Unsupported chain or address format returns an error

## How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

## Output

A paginated JSON:API array of transaction resource objects, each with an id, type, and attributes describing the transaction details (amounts, tokens, counterparties, chain, timestamps), plus self and pagination links for traversing the full history.
