## 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 tzkt-current-statistics-api-71003ee7
```

Example prompt: What is the current total and circulating supply of XTZ on the Tezos network, and how much has been burned so far? Show the values quoted in USD.

## When to prefer this

Choose this endpoint when you need real-time, current Tezos network-level token statistics (supply, burn, lock) without needing to sign up or obtain an API key. It is ideal for dashboards, monitoring agents, and DeFi tools that need up-to-date Tezos economic data. Prefer this over general blockchain explorers when you specifically need structured, machine-readable supply data for Tezos.

## Known failure modes

- Invalid quote currency parameter returns an error or unexpected output
- Network downtime or indexer lag may cause stale data
- Payment failure via x402 protocol prevents access
- Rate limiting if too many calls are made in quick succession

## How this service works

TzKT is a comprehensive Tezos blockchain indexer API. Access blocks, operations, accounts, contracts, bigmaps, delegates, tokens and network stats through a fast REST API. No signup or API key required.

## Output

Returns a JSON object with four integer fields: totalBurned (XTZ burned from the network), totalLocked (XTZ locked in contracts or staking), totalSupply (total XTZ in existence), and circulatingSupply (XTZ actively circulating). Values may be denominated in the requested quote currency (e.g. USD, EUR) if the quote parameter is provided.
