## 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-toolbox-chain-token-total-supply-1e82ddb8
```

Example prompt: What is the total supply of USDC on Base right now?

## When to prefer this

Use this endpoint when you need a quick, no-signup, pay-per-call lookup of a token's total supply on-chain, especially in an autonomous agent context where API key management is impractical and USDC micropayments via x402 are available. Prefer this over managed blockchain data providers when low friction and payment-as-identity is prioritized.

## Known failure modes

- Invalid or unrecognized token/chain schema yields an error response
- Network or RPC timeout on chain data fetch
- Payment not processed or insufficient USDC balance results in 402 rejection
- Malformed schema input returns validation error

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object with an 'ok' boolean indicating success, a 'paid' boolean confirming the x402 micropayment was processed, and the total supply value for the queried token on the specified chain.
