Monitor every rival on X from one API key: follower growth, content strategy, audience overlap, share of voice, and history back to 2006. Clean JSON for your own dashboards, internal tools, or AI agents. Flat-rate, 50x cheaper than the official X API.
Most competitive intelligence on X runs through seat-based SaaS dashboards. They show you data only from the day you signed up, cap how many competitors you can track, and lock everything inside a fixed interface you cannot restructure. If you want to benchmark a rival's strategy from two years ago, you are stuck.
An API inverts that. You pull the raw signals, backfill as far as the data exists, calculate exactly the metrics you care about, and pipe clean JSON into your own dashboards, your product, or an AI agent. The Sorsa API does one platform completely, with full depth on every competitive signal, instead of many platforms shallowly.
Snapshot every rival in a single request and compute weekly follower and posting deltas to see who is gaining ground right now.
GET/info-batch · up to 100 profilesPull a competitor's full tweet history with no 3,200-tweet cap and break down their format mix, cadence, and top posts. See the full 5-phase build guide.
POST/user-tweetsRead who follows a rival, compute shared-audience overlap between competitors, and watch new high-authority followers arrive. You can extract follower and following lists at scale.
·/followers · /verified-followersMeasure your mention volume against the whole category and surface high-engagement complaints that signal feature gaps. You can score sentiment on the results.
·/mentions · /search-tweetsDate-windowed search compares a rival's strategy quarter over quarter or against a launch from years ago. You can pull old tweets at scale.
·since_date / until_dateDiff bios, pinned tweets, and new-following lists to catch launches and partnerships that break on X before any press release.

One request returns up to 100 full competitor profiles. Log it on a weekly cron and you have follower-growth deltas with no SaaS subscription and no OAuth.
Benchmark growth against rivals, catch their launches before the press release, and mine competitor complaints for feature gaps.
Compare content mix and engagement rates across competitors and track share of voice week over week.
Run the same competitive dashboard across every client brand from one API key, with no per-seat SaaS bills.
Track audience quality and momentum across a portfolio or category; crypto sets get an influencer, project, and VC follower breakdown.
Serious competitive work means deep follower pulls and long backfills, exactly the workloads that make per-resource billing explode. Flat-rate keeps the cost predictable no matter how deep you go, and the author profile is included free on every tweet.

Yes. The official X API can do it under pay-per-use pricing and OAuth, and third-party APIs like ours give the same read access (profiles, tweets, followers, mentions, search) behind a single key with flat monthly pricing. You build the tracking logic, you own the data.
A SaaS tool gives you a finished dashboard with seat limits and data only from your signup date. An API gives you raw structured data you build on, with history back to 2006 and no per-seat cost, so you can track as many rivals as you want and put the data wherever you need it.
Yes. Date-windowed search reaches the full public X archive back to 2006, so you can benchmark a rival's strategy quarter over quarter or against a launch from years ago.
Profiles and follower growth, full tweet history and content mix, follower lists and audience overlap, changes in verified followers, mentions and share of voice, and trends. The full build guide walks through each one with code.
Yes, for quick checks. The free Profile Comparison tool puts two accounts side by side and the Engagement Calculator handles per-tweet rate math, both with no API key. For ongoing tracking of several competitors you will script it, and the developer guide has the full pipeline.
Flat monthly plans: $49 Starter, $199 Pro (most popular), $899 Enterprise. On Pro that is roughly $0.0001 per tweet, about 50x cheaper than the official X API, and a viral spike or a deep follower pull never triggers a surprise bill.
