## 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 x402-gateway-wallet-verify-solana-f962a4c3 -d '<json body>'
```

Example prompt: Can you verify that this user actually owns their Solana wallet — they've provided their wallet address and a signed message, and I need to confirm the signature is valid before granting them access.

## When to prefer this

Choose this endpoint when you need to cryptographically verify Solana wallet ownership as part of a Web3 authentication or access-control flow. Prefer over SIWE (wallet_verify_siwe) when the user is on the Solana blockchain rather than EVM-compatible chains. Useful for gating content, validating identity in dApps, or confirming ownership before executing on-chain actions.

## Known failure modes

- Invalid or malformed Solana wallet address returns validation error
- Signature mismatch — signed message does not match expected challenge
- Missing required parameters (wallet address or signature) returns 400-level error
- Payment failure via x402 protocol prevents call from executing
- Network timeout or upstream service unavailability
