Free Implied Move API & Embeddable Widget
The free-layer numbers from the EarningsWatcher wiki — live options-implied earnings moves, 10-year average moves and implied-vs-actual history — as clean JSON and as a drop-in card for your site or newsletter. No API key, CORS enabled, refreshed daily. All we ask: credit EarningsWatcher with a link when you publish from it.
The JSON API
One file per symbol, plus an index of everything covered:
GET https://earnings-watcher.com/api/implied/index.json
GET https://earnings-watcher.com/api/implied/NVDA.json| Field | Meaning |
|---|---|
implied_live_pct | Options-implied move for the next confirmed earnings report (present only while one is upcoming) |
next_date, session | Next confirmed earnings date and session (BMO / AMC) |
average_move_pct, std_move_pct, sample_size | Average absolute earnings move over the last 10 years, its dispersion, and the number of reports behind it |
quantiles_pct | The move distribution (5th / 20th / 50th / 80th / 95th percentiles) |
implied_history | Per-report history: what options implied vs the peak and close move that printed |
as_of, cite_as, url | Data date, the requested attribution, and the source page to link |
Free layer only: member analytics (DriftLab reaction scores, IV Rush signals, scanner, simulator) are not in this feed — they live in the member platform and its MCP server.
The embeddable widget
Two lines. The card shows the live implied move when a report is coming, otherwise the 10-year distribution, and always links the source:
<div data-ew-implied="NVDA"></div>
<script async src="https://earnings-watcher.com/embed/implied-move.js"></script>Live example:
Use any covered ticker (see the index). Multiple cards on one page work — one script tag is enough. The widget adapts to dark mode.
Terms, in plain words
- Free for articles, newsletters, blogs, research and apps — commercial or not.
- Keep the attribution: the widget's built-in link, or for API data a mention of EarningsWatcher linking the
urlfield. - No sub-licensing the raw feed as your own API, and no scraping beyond the published files.
- Educational data, not investment advice; options are risky.
