How the Mascus API works
Mascus is a normal ReefAPI surface — the same four rules that hold for every other engine on the key.
No OAuth app, no request signing, no per-site account. One key covers all 438 engines.
Every route is a POST with a JSON body. Parameters are validated against the published schema before anything is charged.
Credits, not seats. Failed and blocked calls are never charged, and cache hits cost nothing.
One envelope everywhere. meta carries latency_ms, record_count and the endpoint that answered.

Get a free key →What is the Mascus API?▾
Mascus API is a ReefAPI endpoint group for mascus It returns live JSON through POST requests under /mascus/v1.
Is the Mascus API free to try?▾
Yes. ReefAPI starts with 1,000 free credits, no card required. Mascus calls use the same shared credit balance as every other ReefAPI engine.
Do I need a Mascus login or account?▾
No login to Mascus is needed for the API response. You call ReefAPI with your x-api-key header, and the playground can run live examples before you create a production key.
How fresh is the Mascus data?▾
The page example is captured from a live search call, and production requests fetch live data through ReefAPI rather than a static sample.
How many credits does the Mascus API use?▾
Mascus actions currently cost 1-3 credits per successful call. Failed or blocked calls are free. All APIs draw from one credit pool.
Can I call Mascus from an AI assistant or MCP client?▾
Yes. Connect ReefAPI once through MCP and your assistant can call mascus actions with the same key, credit pool and JSON envelope used by normal REST requests.
Is the Mascus API a Mascus scraper?▾
It is the managed alternative to a DIY Mascus scraper. Instead of building and maintaining your own scraper — proxies, headless browsers, captcha and constant breakage — you call one ReefAPI endpoint and get the same mascus back as clean JSON.
Why does my Mascus scraper keep getting blocked?▾
Most Mascus scrapers break on anti-bot defenses, rate limits and IP bans that need rotating residential proxies and browser fingerprinting to clear. ReefAPI handles all of that for you — no proxies, no captchas, no maintenance — and returns live JSON. Blocked calls are free.
191 E-commerce & Marketplaces APIs on the same key
One key, one credit pool, one response envelope. If you are pulling Mascus, you are one call away from the rest of the category — no second contract, no second integration.
Need something this API does not do?
Name the endpoint, the field, or a source we do not carry yet. We ship new APIs every week and you would be first to get the key. Real people read every message and reply the same day.
Try it on your own data before you pay anything
The call above is the real endpoint, not a recording. A free key gives you 1,000 credits, the other 437 APIs, and the same envelope everywhere.
Endpoints, parameters and credit costs on this page are read from the live catalog and cannot drift from what the API accepts.
