# FAQ

## How many networks does FastNode support?

100+ blockchains across mainnet and testnet, including Bitcoin, Ethereum, and all major EVM chains. Don't see yours? Request it at **<support@fastnode.io>**.

## Do I need a credit card to start?

No. Sign up with just your email and use the free plan to test networks. Upgrade only when you need higher limits.

## What's the difference between a full node and an archive node?

A full node keeps only recent state; an archive node keeps the entire history from genesis. Use archive for historical balances, state, and traces. See [Archive Nodes](/advanced/archive-nodes.md).

## What uptime does FastNode guarantee?

**99.99% monthly** for paid endpoints. If we breach the guarantee, you can request a refund for the unused period or a free extension at 10× the downtime — see the [SLA](/reference/sla.md). Public endpoints are best-effort and not covered.

## How do I increase my rate limits?

Upgrade your plan in the dashboard, or contact **<support@fastnode.io>** for a dedicated node.

## Where do I report a problem?

Reach support from the dashboard or email **<support@fastnode.io>**.

## 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://docs.fastnode.io/reference/faq.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.
