The problem

The usual options are not built for API owners.

Big API marketplaces
Take 20 to 30 percent of every transaction and hold your payouts.
Self-hosted billing tools
Cost 25 to 99 dollars a month before you make a cent.
Roll your own
Key management, quota enforcement, and docs hosting: weeks of engineering.

API Mercado is a managed-gateway marketplace with a flat 10 percent fee, payouts into your own Stripe, and no upfront cost.

How it works

List your API in four steps.

01

Upload your spec

Paste a URL or upload an OpenAPI file. Runnable docs render automatically.

02

Set your plans

Free, paid, or invite-only. You set the rate limits and quotas, the gateway enforces them.

03

Connect Stripe

Subscribers pay you directly. The fee is collected at checkout, never held by us.

04

Manage and track

Issue and revoke keys, watch usage, publish revisions, roll back in one click.

Pricing

Straightforward. No surprises.
