Track brand mentions on X without a developer account

The agent reaches X through twitterapi.io: an account profile and its followers, its latest tweets, an advanced search by query and time window, and from there mentions, replies, quotes and whole threads, trends by region, lists, communities and Spaces metadata. On that basis it assembles a day of brand monitoring, breaks a competitor account down by posting cadence and engagement, and shows which mentions deserve a reply first.

The key specific of this route is that access runs not through an X Developer account but through a third-party intermediary with a single key, so there is no application approval to wait for — and equally, only what is public is visible. Direct messages, private accounts and the internal analytics of your own profile are not here. How complete a sample is depends on the query and the search window: the agent states them explicitly and says which period it counted, rather than handing over a slice of some random interval.

This integration has no write actions at all: it is read-only. The agent does not publish tweets, does not reply and does not react on your behalf — a drafted reply comes back to you as text, and posting it is your decision. That is a limit of the source, not a permissions setting: writing cannot be switched on by granting extra access, so no accidental action in your account can arise here either.

Billing here is per item with no monthly subscription: the bill grows with every thousand tweets and profiles read, so the size of a sample is money spent directly. Because of that the agent does not sweep the feed row by row: it narrows the query and the search window, fetches profiles in batches instead of one call per author, and reuses threads it has already pulled. It holds the request rate itself, and if data is missing because of the balance or the key, it says so directly instead of showing an empty list.
