# HTTP status codes — AutoSugges platform dataset

## How do I add HTTP status codes autocomplete to my app?

HTTP status codes is a free AutoSugges reference list of 62 items. Query it with your publishable key as the key parameter and the typed text as q, after at least two characters. Results come back pre-ranked from the edge, ten by default, ready for the AutoSugges React, React Native or HTML component.

62 HTTP status codes with reason phrases, searchable by code or phrase. From the IANA HTTP Status Code Registry.

## Worked example
```json
{
  "value": "408",
  "displayValue": "Request Timeout",
  "aliases": [
    "408",
    "Request Timeout"
  ],
  "metadata": {
    "code": "408",
    "class": "4xx",
    "reference": "RFC9110, Section 15.5.9"
  }
}
```

## Query it
```
/v1/query?key=YOUR_PUBLISHABLE_KEY&q=request
```

A publishable key is public by design and belongs in client code as written; it is not a secret.

## Frequently asked questions

### What is in the HTTP status codes dataset?

62 HTTP status codes with reason phrases, searchable by code or phrase. From the IANA HTTP Status Code Registry. It has 62 items. Its source is Internet Assigned Numbers Authority (IANA). Authority: Authoritative. Licence: IANA's protocol registries are placed under CC0 1.0 — no rights reserved (https://www.iana.org/help/licensing-terms). Refresh cadence: As RFCs register or retire status codes; infrequent.

### Is the HTTP status codes dataset free?

AutoSugges-published free datasets are never priced on their own — every plan includes all of them. What a plan prices is how many queries you may make, not which free list you may query. A few catalog entries are licensed from a third party or supplied by you, and those carry their own access terms, shown on that dataset's own page.

### How do I query HTTP status codes?

Call GET /v1/query with your publishable key as the key parameter and the typed text as q, or mount the AutoSugges component for React, React Native or HTML. The runtime answers from the edge and never reads a database.

### What is the minimum number of characters before a query runs?

Two by default. A list owner can change the minimum, but it can never be 1. The client reads the real value from bootstrap and sends no request below it, so do not hardcode it.

### How long does the client wait after typing before it queries?

150 milliseconds by default. The value is delivered through bootstrap and a list owner can raise it, so the client uses the policy value rather than a constant.

### What happens when my query quota runs out?

The runtime returns a structured quota_exceeded response that carries no items and no placeholder suggestions, so exhaustion is never mistaken for no results. Render it from the typed error code and prompt an upgrade.
