Quick Start

No sign-up required. The core endpoint is public and free.

Terminal window
curl https://polystrike.xyz/api/v1/meta/elon

You’ll get back something like this:

{
"timestamp": 1771246725679,
"data": [
{
"event_id": 206602,
"event_title": "Elon Musk # tweets February 14 - February 16, 2026?",
"start_ts": 1771088400000,
"end_ts": 1771261200000,
"polymarket_xtracker_counter": 65,
"real_counter": 68,
"polymarket_ui_counter": 65,
"settlement_delta": 3,
"display_delta": 3,
"internal_delta": 0
}
]
}

What you’re seeing: The real count is 68 but the settlement oracle (XTracker) only shows 65. That settlement_delta of 3 means Polystrike has found 3 tweets the oracle hasn’t counted yet. The UI is also showing 65 — so traders on Polymarket are looking at a number that’s 3 behind reality.

The three delta fields are your edge signals:

FieldFormulaWhat a positive value means
settlement_deltareal − xtrackerPolystrike is ahead of the oracle
display_deltareal − uiThe UI is showing a stale number
internal_deltaui − xtrackerThe UI is ahead of or behind the oracle
Terminal window
curl https://polystrike.xyz/api/v1/meta/elon/tweets

Returns the 15 most recent tweets (free tier). Each tweet includes type flags (is_reply, is_quote, is_retweet) and a is_counted field that tells you whether it counts toward settlement.

If you use Claude Desktop, skip the manual API calls and connect via MCP instead:

Pro unlocks the prediction model, is_counted classification, full tweet history (with pagination), and trading signals.
