Filter by date

from_date and to_date bound results by publication date. Either can be an absolute date or an offset from now, and you can pass one or both. An absolute bound is a date, 2025-10-28, or a datetime, 2025-10-28T23:00:00Z. A relative bound is now, or now- and one duration, such as now-7d for the past week.

Unit	Meaning
`s`	second
`m`	minute
`h`	hour
`d`	24 hours
`w`	7 days
`M`	one calendar month
`y`	one calendar year

A count and a unit are both required, and case matters: m is minutes, M is months.

Times are UTC. A date with no time starts that day on from_date and covers the whole of it on to_date.M and y step the calendar rather than a fixed number of seconds, and clamp the day to the length of the target month, so now-1M from 31 March lands on 28 or 29 February.

The examples below return results published in the past week.

from seltz import Seltz

client = Seltz()

response = client.search("ai search funding", from_date="now-7d")

for doc in response.documents:
    print(f"- {doc.url}")

import { Seltz } from "seltz"

const client = new Seltz();
const result = await client.search({ query: "ai search funding", fromDate: "now-7d" });

for (const doc of result.documents) {
  console.log(doc.url);
}

curl -X POST https://api.seltz.ai/v1/search \
  -H "x-api-key: $SELTZ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "ai search funding", "from_date": "now-7d"}'

A date filter narrows what is returned. It does not promise that anything published in the window has been indexed yet, so a window of an hour or two can come back empty.
