# Fast Decrease in Priority Fees (Tips) Alert - DEPRECATED

<mark style="color:red;">**THIS ENDPOINT HAS BEEN DEPRECATED AND WILL NO LONGER BE ACTIVELY MAINTAINED, UPDATED OR SUPPORTED**</mark>

**Alert Definition**

Alerts if the Priority Fees (or tips) of a block are lower than its 100-block predecessors. For context, the concept of a Priority Fee, or tip, was introduced as part of EIP-1559 and it represents the portion of the total transaction fees that rewards miners. This serves as an added incentive so that miners prioritize transactions that have opted-in and paid a tip. The other portion is called the Base Fee, and it is burnt (destroyed) after the transaction is included in a block

**Interpretation**

A consistent decrease in Priority Fees might occur organically as demand for block space decreases. It can also be a sign of more concerning circumstances if persistent. For example, a decrease in Priority Fees at a time when there is visible demand for block space might be a sign of so-called out of band payments, which are payments made by transactors directly to miners.

**Potential Root Causes**

Organic decrease in demand for block space. Out of band payments made directly to miners.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gitbook-docs.coinmetrics.io/network-data/deprecated/watchtower-alerts-overview-deprecated/watchtower-alerts-deprecated/ethereum-proof-of-stake-alerts-deprecated/fast-decrease-in-priority-fees-tips-alert-deprecated.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
