ChatterAPI vs twitterapi.io

twitterapi.io is a third party API for X data. It is priced per result and offers webhooks, websockets and a read-only MCP server. ChatterAPI covers X and Reddit with one key and charges a fixed number of credits per call. If you only need X and want real-time delivery, twitterapi.io is built for that job.

What twitterapi.io is

It describes itself as an API for public X data, built for developers and AI agents, that works without X developer approval. source
As listed on Oct 17, 2026, it charges $0.15 per 1,000 tweets and from $0.01 per 1,000 profiles, with a $0.00015 minimum per call. source
Requests use a single x-api-key header. There is no OAuth. source
Its rate limit page lists 1 request every 5 seconds for accounts that have never topped up, and 20 requests per second after a top-up. source
Write endpoints need login cookies from its login endpoint, which takes the account's credentials. source
Its docs list webhook and websocket filter rules and per-user tweet monitoring. source
Its MCP server has 12 read-only tools. It cannot post, like, follow or send DMs. source

Choose twitterapi.io when

You only need X, at high volume, priced per result.
You need real-time tweets through webhooks or websockets.
You need X endpoints we don't list, such as trends or communities.

Choose ChatterAPI when

You need Reddit as well as X, with one key and one response shape.
You want X actions from accounts connected in a dashboard, so your code never sends account passwords.
You want an MCP server that can also act on X from connected accounts.
You want a fixed credit cost per call that you can budget before you run.
