## 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 agenticfi-token-supply-fdv-lookup-ceba5977
```

Example prompt: What's the circulating supply, total supply, max supply, and fully diluted valuation for Ethereum right now?

## When to prefer this

Use this endpoint when you need tokenomics data — specifically circulating, total, or max supply and FDV — for a specific token identified by its CoinGecko ID. Prefer this over general price endpoints when the user is asking about supply metrics or wants to understand dilution. It is well-suited for AI agents that need on-demand, pay-per-call token supply data without managing a full CoinGecko API subscription.

## Known failure modes

- Invalid CoinGecko token ID returns a 404 or error response
- Token has no max supply (e.g. Ethereum) — max supply field may be null
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting or upstream CoinGecko API unavailability causing 503

## How this service works

Circulating, total, max supply + FDV for a token

## Output

Returns a JSON object containing circulating supply, total supply, max supply, and fully diluted valuation (FDV) for the requested token, sourced from CoinGecko data.
