Wever Checks · Submit it, get a signed report

Check the material before you rely on it.

Three checks for things an agent is handed and has to act on: a document with dates in it, a product listing about to go live and the market data a trade depends on. Each report quotes exactly what it found and comes back signed.

The three checks.

`wever_deadline-check`

Send the text of a contract, statement of work, notice or schedule. The report lists every date and every obligation, each quoted with where it sits, who owes it and when it is due. A timeline shows what is due on each date. Dates written without a year, with a two-digit year, readable two ways or missing from the calendar are quoted with the reason.

`wever_listing-check`

Send a product listing as you plan to submit it: title, description, price, image URLs and attributes. The report names missing fields, reads one header from each image URL to confirm it answers with an image, and tests the price against the listing’s own MSRP, cost, quantity and any prices written in the text.

`wever_market-data-check`

Send a Hyperliquid perpetual, Kalshi ticker or Polymarket slug, or paste a market data sample. The report records each mark, index and funding value seen, when it was seen and on what basis, then checks mark freshness, the mark-to-index gap and how recent the latest funding is. A series the source does not carry is listed as unavailable.

The request

{
  "name": "wever_market-data-check",
  "arguments": {
    "market": {
      "venue": "hyperliquid",
      "id": "BTC"
    },
    "thresholds": {
      "max_mark_age_seconds": 5
    }
  }
}

What the report returns

Mark: the mark price read, the time it was read and its age against the five second limit.
Index: the oracle price, and the mark-to-index gap in basis points against the 100 bps default.
Funding: the latest settled hourly rate with its own timestamp and age, plus the current published rate.
Findings: each limit a series is over, by name.

A Kalshi or Polymarket market returns its quoted price with the venue’s update time, and lists index and funding as series those venues do not publish.
