# CEX Reserves Snapshot

> CEX Reserves Snapshot is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a normalized on-chain reserve breakdown for a centralized exchange, including total TVL, clean-asset TVL, own-token exposure, netflows, and trading volumes.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 cex-reserves-snapshot-99d17f06
```

Example prompt: Can you pull the on-chain reserve breakdown for OKX — I want to see the total TVL, how much is clean assets versus their own token, the clean-asset ratio, and any 24h/1w netflow numbers?

## When to prefer this

Use this endpoint when you need a quick, cheap first-pass look at a centralized exchange's reserve health — specifically TVL, own-token risk, and netflows — before deciding whether to run a deeper solvency analysis. Ideal when cost matters and you want raw normalized reserve data rather than a full verdict. Prefer this over broader financial data APIs when the data is specifically about CEX proof-of-reserves sourced from DefiLlama.

## Known failure modes

- Unknown or misspelled exchange name/slug returns a 404 or empty result
- Exchange not tracked by DefiLlama returns no data
- DefiLlama upstream outage causes stale or unavailable data
- Missing required 'cex' query parameter returns a validation error
- Exchange has no on-chain reserves published, resulting in null TVL fields

## How this service works

Cheap raw normalized reserve breakdown of one centralized exchange: total on-chain reserves (currentTvl), clean-of-own-token reserves (cleanAssetsTvl), the own-token symbol / USD value / concentration, clean-asset ratio, spot & derivative volumes, leverage, 24h/1w/1m netflow and the public reserves URL, with citations. The cheap first grain before the fuller /cex/solvency verdict. Keyless DefiLlama source; reserves are a proxy, not proof of solvency.

## Output

A normalized JSON object containing: total on-chain reserves (currentTvl), clean-of-own-token reserves (cleanAssetsTvl), the exchange's own token symbol and its USD value and concentration percentage, the clean-asset ratio, spot and derivative volumes, leverage figure, 24h/1w/1m netflow values, and a link to the exchange's public reserves page — all sourced from DefiLlama.
