ShowMRR API

Read-only JSON over HTTPS. No API key.

The same data that powers showmrr.com is available as JSON. Everything here is a GET request that works from a terminal or a script today. Base URL: https://showmrr.com/api

Read this first: verified vs self-reported

Every revenue figure carries a label. isVerified is true only when ShowMRR read the figure from a payment provider the founder connected (Stripe, Lemon Squeezy or Polar) and the last read was recent. Otherwise the figure is self-reported: typed in by a person, or read from a public page the founder publishes (publicSource says which page and when). revenueAsOf is the date the number was last read or edited.

If you republish a figure, please keep its label and date next to it. A self-reported number shown without that context is the thing this API exists to avoid.

Basics

Money is in minor units (cents), so currentMrrCents: 92919800 is $929,198. mrrCurrency is the currency code, lowercase.
Timestamps are ISO 8601 in UTC.
Lists come back as {"data": [...]}. Most accept limit (1–100, default 20 or 50) and offset.
Rate limit: 100 requests per minute per IP address. Over the limit you get 429 with a Retry-After header (seconds).
Errors are JSON: {"error": "..."} with 400, 404, 405 or 429.
No versioning or guarantees. The API is unversioned and may change. Fields may be added; check revenueAsOf rather than assuming freshness.

`GET /api/startups/:id/revenue`

Daily revenue history for a startup (id or slug). Parameter: days (1–365, default 30). source is where each point came from: a provider name, or public_page for a figure read from the founder's own page.

  "data": [

      "snapshotDate": "2026-10-18T00:00:00.000Z"
    }
  ]
}

`GET /api/search`

Search and filter. With no q and no filter it returns an empty list. Parameters: q (words, prefix matching), category, mrr_min and mrr_max (in cents), growth_min, growth_max, followers_min, followers_max, founded_min, founded_max, audience (b2b or b2c), sort (mrr, growth, newest, followers), limit, offset.

curl 'https://showmrr.com/api/search?q=analytics&mrr_min=100000&sort=mrr'

`GET /api/categories`

Categories that have listings, with count, totalMrrCents and verifiedCount. GET /api/categories/:slug lists the startups in one category (limit, offset).

`GET /api/stats`

Platform totals: startupCount, verifiedCount, founderCount, totalMrrCents, a revenue distribution and a per-category breakdown. Note that totalMrrCents adds up every listed figure, including self-reported ones; verifiedCount says how many startups are provider-verified.

Other lists

GET /api/top-100 — the first 100 leaderboard entries, in the same shape as /api/leaderboard.
GET /api/recently-added — newest listings (limit).
GET /api/tech-stack — technologies in use, with startup counts.
GET /api/feed — the activity feed.

Fair use

Use the API for your own tools, research and apps, and keep the rate limit. Please don't mirror the whole database as a competing directory. If you need more than 100 requests a minute or a bulk export, write to support@showmrr.com.

A quick example

curl -s 'https://showmrr.com/api/leaderboard?withRevenue=true&limit=3' | jq '.data[] | {{name, currentMrrCents, isVerified, revenueAsOf}}'
