The Marchex API evolves without warning — endpoints move, parameters change, auth scopes tighten and old fields get deprecated. apik.dev watches the public Marchex API documentation for you: we scrape it on a schedule, diff every revision and grade each change as breaking or informational. Instead of re-reading the Marchex changelog by hand, you get a clean, dated record of exactly what changed — and why it matters.
Subscribe to Marchex and apik pages you by email or webhook the moment a change is detected — with the full diff, a severity grade and a short migration summary. Filter to Marchex breaking changes and deprecations only, so you hear about what will actually break your integration and nothing else.
apik is in private development. Join the waitlist and we'll email you the moment Marchex tracking goes live — full diffs, severity grading and migration summaries.
