X’s self-serve API is pay-per-use from prepaid credits: $0.005 per post read, $0.010 per user or follower returned and $0.015 per post created, capped at 3 million post reads a month. Enterprise contracts lift the cap and add the full firehose. X is moving subscribers of its old fixed plans, $200 or $5,000 a month, onto pay-per-use.
Is there a free X API?
Not for most new apps. X’s API runs on prepaid credits, and only apps X classes as Public Utility Apps keep free access. For public data, most data APIs let you start free: Monocrawl gives 1,000 credits every month, Bright Data 5,000 records a month, Apify $5 of usage a month, Xpoz 500 credits once, Sorsa API 100 requests and SociaVault 50 credits.
Can I search posts older than a week?
Yes. X’s pay-per-use API has recent search over the last 7 days and full-archive search back to 2006. Monocrawl’s post search takes a date window with from and to dates.
Do I need an X developer account to use a data API?
Not with Monocrawl: you send your Monocrawl API key and get public X data back, with no X login and no developer app. The official API needs a developer account, an app and prepaid credits, and X’s terms require Enterprise beyond early-stage use or a limited number of end users.
Which X APIs work with AI agents?
Monocrawl, X itself, Apify, Bright Data, SociaVault, Sorsa API and Xpoz publish their own MCP servers, so assistants such as Claude or Cursor can call them directly. X’s server runs through your own X developer app.
How should I compare prices?
Units differ: X bills per post or user returned, while most data APIs bill per call, result or record, and one call can return a page of about 20 posts. Price your own workload, such as a number of posts or profiles a month, with each vendor.

How we compared.
What’s includedX’s own API in its two current forms, pay-per-use and Enterprise, plus a selection of X data APIs that publish their pricing or offer a trial and come up across X API searches and comparison lists.
