## How to call it through Zero

```sh
zero fetch --capability chainray-token-supply-lookup-1a529eb4
```

Example prompt: What's the total token supply for the contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum?

## When to prefer this

Use this endpoint when you need on-chain token supply data (total, circulating, or max) for a specific token contract address across any of 46 supported chains. Prefer ChainRay over generic block explorers when you need programmatic, pay-per-request access with consistent JSON output and multi-chain support in a single API.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain identifier causes a 400 or 422 error
- Address is a wallet rather than a token contract, returning no supply data
- Network congestion or RPC unavailability causes a timeout
- Payment not processed (402) if x402 header is missing or invalid

## How this service works

The most complete blockchain data and intelligence service for AI agents. 93 endpoints across 46 chains, from gas fees to DeFi analytics, with real-time streams, intent routing, and verifiable proofs. Pay-per-request via x402.

## Output

Returns on-chain token supply data for the specified contract address, including total, circulating, and/or max supply figures denominated in the token's native units, sourced directly from the blockchain.
