## 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 cambrian-x402-solana-holder-token-balances-bb4b0f10
```

Example prompt: What token balances does the Solana wallet address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU currently hold? Pull the full list of holdings.

## When to prefer this

Choose this endpoint when you need on-chain Solana token balance data for a specific wallet address and want pay-per-use pricing without a subscription. It is ideal for agents that only occasionally need token holder data, want to avoid API key management overhead, and can pay micropayments via x402. Prefer this over general blockchain explorers when you need structured, machine-readable token balance output directly consumable by an autonomous agent.

## Known failure modes

- Invalid or malformed Solana wallet address returns an error or empty array
- Payment failure via x402 protocol results in 402 response and no data
- Unknown or new wallet address with no token history may return an empty array
- Rate limiting or network congestion may cause timeouts
- Unsupported query parameters may be silently ignored or cause a 400 error

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

An array of token balance records for the queried Solana wallet, including token mint addresses, amounts, and related holdings data for all tokens held by the address.
