A SERP & keyword API for agencies

Agencies juggle many clients with very different volumes. A flat monthly platform makes you pay for seats and quota you do not use. The Kwinside APIs are pay-as-you-go, so cost scales with each client's real usage instead of a fixed plan.

What you can build

Multi-client rank dashboards, white-label reports, automated audits and pitch research. Pull SERP positions, keyword volumes and competitor data for any client from one integration and one balance.

Why Kwinside fits

Per-request billing means a small client costs a few cents and a big one scales smoothly — no per-seat fees. Six languages cover international clients, and the data is raw JSON you can drop straight into your own reporting.

Getting started

Create one account, top up once ($20 minimum), and route all clients through a single key. Evaluate on the free 20-requests-a-day tier before you spend.

Frequently asked questions

Is there an agency or per-seat plan?

There are no seats. Kwinside is pay-as-you-go at $0.002 per request, so you pay for the data you actually pull across all clients, with a $20 minimum top-up.

Can agencies use the data in client reports?

Yes. The API returns raw JSON for SERP, keyword and competitor data, which you can present in your own white-label dashboards and reports.
