Social listening API
Social listening for Reddit and X, as an API.
Watch keywords, brands, communities and accounts across Reddit and X. Weir checks on a schedule, keeps only what is new, and sends each find to your webhook — or your agent.

Build it into your product, not a dashboard
Social listening suites are built for marketing teams reading dashboards. If you are building a product, an internal tool or an agent, you want the raw mentions as JSON, on your schedule, in your own pipeline.
Monitors, not polling loops
Define what to watch once. Weir runs it on a schedule and reports only results it has not reported before.
Signed webhooks
Each new find arrives as a signed POST you can verify, with retries when your endpoint is down.
Reddit and X together
One monitor can search both platforms, and each result keeps its platform's own fields.
Priced per mention
You pay for results found, not seats or tracked keywords. A quiet week costs almost nothing.

Questions
What can a monitor watch?
A search across Reddit and X, a subreddit's new posts or comments, a Reddit or X account, or a single thread.
How often does it check?
On the schedule you choose when you create the monitor; the dashboard and the docs list the available schedules.
Does it do sentiment analysis?
No. Weir delivers the mentions; you, or your model, decide what they mean. That keeps the data unmodified and the bill small.
Can my AI agent manage monitors?
Yes. With the monitor permissions granted, the MCP server exposes tools to create, list and read monitors and their results.
