PostgreSQL API builder

Build a no-code PostgreSQL API with Streamnode using PostgreSQL as your connected datastore.

Easily build a PostgreSQL API

  • Create a no-code PostgreSQL API from HTTP request to response in minutes
  • Use PostgreSQL datastore capabilities to power endpoint logic
  • Add auth, validation, and response shaping without backend boilerplate
  • Publish production-ready endpoints with built-in request tracing

Start with a ready made template

Open a ready-made PostgreSQL API builder template in Streamnode, then customize the request, actions, and response for your project.

Build APIs by composing connection capabilities

Use each connection as a capability layer, then combine validation, actions, and responses into complete endpoint behavior.

Compose endpoint behavior

Turn connection capabilities into complete API flows.

  • Datastore connections expose capabilities for querying, creating, updating, and deleting structured data directly inside endpoint workflows.
  • Filestore connections expose capabilities for writing files, reading content, checking paths, and returning signed or direct URLs.
  • Integration connections expose action capabilities that let an API endpoint trigger communication, automation, or AI side effects.
POST streamnode.app/submit-form
01
Validate

Check auth, params, and accepted input shape.

02
Run actions

Call connections and branch on outcomes.

03
Respond

Return the right HTTP status and payload.

Policy layer

Constrain who can call the endpoint and what data is accepted.

Response mapping

Map capability results to success, failure, missing resource, or policy responses.
