StockSplitWatcher developer & agent resources

Public stock split checker API

The same lookup that powers the stock split checker is available as JSON:

GET https://www.stocksplitwatcher.com/api/stock-split-checker?symbol=AAPL

• Returns upcoming splits, splits completed in the last 90 days, and recent SEC filings containing stock-split language, with source links.
• No authentication. Rate limited to 30 requests per minute per client; a 429 response includes a Retry-After header.
• Errors: 400 for a missing or invalid symbol, 404 for an unknown ticker. All responses are JSON with success, message, and data fields.
• A filing-language match is a screening signal, not confirmation that a split will occur. See the methodology.

Markdown content negotiation

Public pages honor Accept: text/markdown and return a markdown representation of the same URL with Vary: Accept, so agents can read pages without parsing HTML:

curl -H "Accept: text/markdown" https://www.stocksplitwatcher.com/

This works on the homepage, about, pricing, FAQ, methodology, contact, the stock split checker, the stocks directory, this page, and every blog article.
