# Uzo Index

> A planned indexing service for querying BOT Chain events and history.

<Info>
  **Planned.** This service is not live yet. This page explains what it will do and what to use in the meantime.
</Info>

Learn what Uzo Index is meant to do for BOT Chain apps and how to get indexed data today without it.

## Why it's needed

Apps often need questions answered across many blocks: every transfer for a wallet, every swap in a pool, the top 10 holders of a token. Answering those from raw RPC calls is slow, and on BOT Chain it's harder because `eth_getLogs` is documented as disabled on the public endpoints. See [Logs and WebSockets](/infrastructure/rpc/logs-and-websockets).

## What Uzo Index will do

Uzo Index is planned as a hosted index of BOT Chain events that lets you:

* Query decoded events for your contracts without scanning blocks yourself.
* Get history from a contract's deployment, not only recent blocks.
* Serve data to your frontend from one API instead of many RPC calls.

It depends on a logs-enabled RPC, which is what [Uzo RPC](/infrastructure/rpc/overview) is planned to provide. API shape, pricing and limits will be published at launch.

## What to use meanwhile

| Option | Good for | Guide |
| - | - | - |
| BOTScan API | Decoded logs, transactions, token holders | [Use the BOTScan API](/guides/data/explorer-api) |
| Chunked `eth_getLogs` | Recent events for one contract | [Known limitations](/get-started/bot-chain/known-limitations#event-queries) |
| Contract state | Counts, recent items, leaderboards | [Events without getLogs](/guides/frontend/events-without-getlogs) |
| Your own node and indexer | Full control at scale | [Index chain data](/guides/data/indexing) |
