# HTTP API

Data may be queried by posting SQL to the `/v1/sql` API and `/v1/firesql` API for Firecached data. For documentation on the Spice Firecache see [Broken mention](broken://pages/q4t8COjPZrT3eUwQXMBw).

See [Tables](broken://pages/raer32Dk4PPuKbzd1GLs) for a list of tables to query or browse the example queries listed in the menu.

#### Requirements and limitations

* An API key is required for all SQL queries.
* Results are limited to 500 rows. Use the [Apache Arrow Flight API](/api/runtime-apis/sql-query/apache-arrow-flight-api.md) to fetch up to 1M rows in a single query or the [Async HTTP API](broken://pages/INalDm4gLljuBB16j2bY) to fetch results with paging.
* Requests are limited to 90 seconds.

# Agent Instructions: 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:

```
GET https://docs.spice.ai/api/runtime-apis/sql-query/http-api.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
