# Update Settings

> Configure settings for your Realtor Listings Scraper squid

Update the configuration of your **Realtor Listings Scraper** squid. Pass crawler-specific settings inside the `params` object.

## Headers

<ParamField header="Authorization" type="string" required>
  Your API authentication token. Value: `Token YOUR_API_KEY`
</ParamField>

<ParamField header="Content-Type" type="string" required>
  Must be application/json. Value: `application/json`
</ParamField>

## Body

<ParamField body="params" type="object">
  Crawler-specific settings. See fields below.
</ParamField>

## Settings Fields

<ParamField body="params.max_results" type="integer">
  Maximum number of listings to collect per task. Leave empty for unlimited.
</ParamField>

<ParamField body="params.max_unique_results_per_run" type="integer">
  Maximum number of unique results across all tasks in a run. Leave empty for unlimited.
</ParamField>

<ParamField body="params.property_details" type="boolean">
  Visit each listing detail page to collect the full photo gallery, agent and office details, description text, price/tax history, schools, spec sheet, risk scores, and more. Requires one additional request per listing.
</ParamField>

<ParamField body="params.keyword" type="string">
  Filter listings by one or more keywords, comma-separated (e.g. `pool, ocean view`). Only listings whose description contains at least one keyword are returned.
</ParamField>

<ParamField body="params.fetch_since" type="string">
  Only collect listings published after this point (based on `published_at`). Accepts a relative duration (e.g. `"24h"`, `"7d"`, `"2w"`) or an absolute date (`"YYYY-MM-DD HH:MM"`).
</ParamField>

<ParamField body="params.fetch_since_timezone" type="string">
  Timezone for interpreting an absolute `fetch_since` date (e.g. `"America/New_York"`). Only applies when `fetch_since` is an absolute date — ignored for relative values like `"24h"` or `"7d"`.
</ParamField>

<Tip>
  Set `fetch_since` to `null` to collect all listings, or use a relative duration (`"24h"`, `"7d"`, `"2w"`) or absolute date (`"YYYY-MM-DD HH:MM"`) to collect only recent listings. When using an absolute date, set `fetch_since_timezone` to interpret it in the correct timezone (e.g. `"America/New_York"`).
</Tip>
