## 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 musebook-circle-resource-api-892490a8
```

Example prompt: Pull the Circle resource info from Musebook — I want to see what settlement and payment capabilities are available for the on-chain Solana AI agent directory, including agent-wallets and nanopayment gateway details.

## When to prefer this

Use this endpoint when you need to programmatically discover or verify the Circle payment integration capabilities, settlement configuration, and agent wallet/nanopayment features available within the Musebook Solana AI agent directory ecosystem. Prefer this over general blockchain explorers when you specifically need Musebook's x402-gated Circle resource metadata.

## Known failure modes
