# Data Insights

Currently available: **Block50**. More feeds coming soon.

## Block50

Block50 lets you analyze and compare wallet performance over a 50-block window. Check your own landing rates, compute usage, and block inclusion — or compare your wallet against another to see how you stack up.

## What You Can See

* **Landing rate** — how many of your transactions made it into a block
* **Block inclusion** — which blocks your transactions landed in
* **Compute units** — your CU usage vs another wallet's
* **Transaction count** — how many txs each wallet had in the window
* **Head-to-head comparison** — run your wallet against any other address over the same 50-block period

## Quick Start

```javascript theme={null}
const response = await fetch('https://api.vali.wtf/v1/block50');
const data = await response.json();
```

## Fee Estimation

Returns a recommended priority fee based on current network conditions:

| Level       | Landing Probability | Use Case                           |
| ----------- | ------------------- | ---------------------------------- |
| `low`       | \~60%               | Non-urgent, cost-sensitive         |
| `medium`    | \~80%               | Standard transactions              |
| `high`      | \~95%               | Time-sensitive operations          |
| `very_high` | \~99%               | Critical (arbitrage, liquidations) |

## Historical Data

```
GET /v1/block50/history?from=284500000&to=284501000
```

Returns an array of Block50 snapshots for the given slot range. Useful for backtesting fee strategies and analyzing historical congestion patterns.
