What people build with the X Post Search API

Social listening

Every recent post that mentions your product, a competitor or a pain you solve.

Find warm leads

People posting about the exact problem you fix are the people to talk to first.

Track a launch

Search the launch name and read how it is landing, post by post.

Quote it, then run it

1. free quote: the exact price, nothing charged

curl -X POST https://apiforagents.dev/v1/x_twitter \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"searchPosts","query":"electric cars","limit":25,"estimateOnly":true}'

2. the same call, run

curl -X POST https://apiforagents.dev/v1/x_twitter \
  -H "Authorization: Bearer $AFA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"op":"searchPosts","query":"electric cars","limit":25}'

Inputs

Everything you can send in one searchPosts call. Required inputs first.

Input	Type	What it does
query *	string	≤300 chars
limit	integer	1-50

What comes back

The fields of every row, always present. Nothing is guessed: a value that could not be measured is null, and the answer's coverage says why.

Show all 28 rows

Field	Type
postId	string
body	string
kind	string
postedAt	string
permalink	string
language	string
mediaUrl	string
likes	integer
replies	integer
reposts	integer

views	integer
bookmarks	integer
isReply	boolean
isQuote	boolean
isPinned	boolean
replyToHandle	string

repostedPostUrl	string
hashtags	list of string
mentions	list of string
authorUsername	string
authorId	string
author	object
conversationId	string
media	list of object
outboundLinks	list of string
details	object

details is always the last field: everything else the source sent for that row, under our own field names. Its keys depend on the source that answered, so read them defensively; it is {} when there is nothing more.

A sample answer

Made-up names and values in the real field names, so you can see the shape before you spend anything.

Pricing

Pay as you go, in US dollars, per record. No subscription, nothing expires, $5 first top-up, and every new agent starts with $0.10 free.

Request	Records	At the list price
One post	1	$0.000225
10 posts	10	$0.0022
A full page	50	$0.011

These are per-record list prices. Some calls also carry a minimum, such as a page of search results, so a small request can cost more than the table shows. The quote ("estimateOnly": true) is free, gives the most your exact request can cost, and the charge then settles to what came back. Records that do not come back are refunded.

Try it without writing code

Open the X Post Search API in the playgroundThe playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type.

Why this one, and not a scraper you run yourself

No login, no X / Twitter account, no cookies, no proxies, no browser to babysit.
When the site changes its pages, your request stays the same: keeping the reads working is our job, not yours.
A fetch that fails costs nothing: it is named in the answer with a reason, and the quote says the most a call can cost before it runs.

Use it from your tools

Questions people ask.

How is post search different from the posts API?

The posts API reads one account's recent posts. Post search finds posts by keyword across all of X, from anyone.

What does it return?

One row per post: author username, text, kind, posted time, views, likes, reposts, replies, quotes, post id, permalink, media URL, whether it is a reply, quote or pinned, the quoted or reposted post URL, and author id.

What do I pass in?

A query (up to 300 characters) and a limit from 1 to 50.

How much does it cost?

$0.000225 per post at the list price. A small call can carry a minimum, so quote first with "estimateOnly": true, which is free and is the most the call can cost. You pay for what comes back.

Why people pick API for Agents

One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
$0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
Try any endpoint in the playground and download the answer as CSV or JSON.
