Explore the cloud as serverless building blocks


M3O transforms public APIs into smaller easier to use Micro services which you can explore, discover and consume as serverless building blocks. The platform generates unified api docs, client libraries and examples on top of Micro services using protobuf to OpenAPI conversion and some custom tooling. The API gateway manages access using a pay per request billing model by debiting from a virtual wallet which you can topup via a standard credit or debit card.


Here are the main features:

  • 1️⃣ ONE Platform - Discover, explore and consume public APIs all in one place.
  • ☝️ ONE Account - Manage your API usage with one account and one token.
  • ⚡ ONE Framework - Learn, develop and integrate using one set of docs and libraries.


So far there are over 60+ services. Here are some of the highlights:

☁️ Cloud
  • Apps - Serverless app deployment
  • Database - Serverless postgres database
  • Functions - Serverless lambda functions
  • Events - Publish and subscribe to messages
  • Users - User management and authentication
  • Space - Infinite cloud storage
  • Search - Indexing and full text search
🗺️ Logistics
  • Address - Address lookup by postcode
  • Geocoding - Geocode an address to gps location and the reverse.
  • Location - Real time GPS location tracking and search
  • Places - Search for geographic points of interest
  • Routes - Etas, routes and turn by turn directions
  • IP2Geo - IP to geolocation lookup
⚙️ Miscellaneous
  • Email - Send emails in a flash
