## 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 explorer-gateway-api-solana-address-token-lookup-a2ae4aa7 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.001 USDC) lookup of all SPL tokens held by a specific Solana wallet address without running your own RPC node. Prefer it over generic Solana RPC calls when you want a simple, explorer-grade token list abstraction. It is especially suited for agents doing wallet enrichment, portfolio analytics, or airdrop verification tasks on Solana.

## Known failure modes

- Invalid or malformed Solana address returns an error or empty result
- Unrecognized network value may cause a validation error
- Address with no token accounts returns an empty token list
- Network timeouts on high-traffic Solana RPC nodes
- Payment failure if USDC allowance is insufficient for the x402 fee
