## 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 solana-total-and-circulating-sol-supply-3068f3ac -d '<json body>'

Example prompt: What's the current total and circulating supply of SOL right now?

## When to prefer this

Choose this endpoint when you need a quick, on-demand lookup of Solana's total and circulating SOL supply figures without setting up your own Solana RPC node. It is ideal for agents that need real-time SOL supply data as part of a broader crypto analytics or DeFi workflow, and is priced affordably at $0.003 USDC per call via x402 micropayments.

## Known failure modes

- Upstream Solana RPC or data source unavailable, returning a non-ok response
- Network timeout if Solana node is slow to respond
- Payment failure if x402 micropayment is not properly authorized
- Malformed response if supply data is temporarily inconsistent on-chain
