Build on the SYNE data layer

SYNE APIs. Every product on the platform.

Risk scores, emissions data, financed-emissions calculations, traceability records - all available through the same authenticated REST API used internally by every SYNE product. Pull it into your own systems, or build something new on top of it.

What's included

Everything you need to build on SYNE.

The same API surface used internally by every SYNE product - documented, sandboxed and ready to authenticate against.

API Documentation

Full reference documentation for every endpoint, with request and response examples for each product API.

SDKs

Official libraries for Python, Node.js, Java, Go and Ruby, so you're not hand-rolling HTTP calls.

Sandbox Environment

A fully isolated environment with realistic sample data, so you can build and test before touching production.

Webhooks & Data Feeds

Subscribe to risk-score changes, new disclosures or trace-record updates instead of polling for them.

Authentication & Rate Limits

Bearer-token authentication with per-key rate limits, scoped to exactly the product APIs you need.

Browse the API

One namespace per product, every API it exposes.

Every product on the platform breaks down into a set of specific APIs under its own namespace - organised by product, so you can pull exactly the data you need.
