Developer Platform

FreeSyntax exposes a stable, machine-readable integration surface for search engines, AI answer engines, and programmatic clients. All integrations consume Application Services through REST v1 — never duplicated domain logic.

Official SDK (@freesyntax/sdk)
TypeScript client for feed, identity, evidence, search, federation, webhooks, and authentication helpers.

Federation Layer
Cross-instance Engineering Identity references, trust policies, and signed event synchronization.
https://freesyntax.com/federation
Federation Discovery
Machine-readable node discovery for federated instances.
https://freesyntax.com/api/v1/federation/discovery

AI & answer-engine discoverability

Public Engineering Identity pages, Knowledge Entries, Communities, and this developer hub publish JSON-LD structured data with stable canonical URLs. Query search URLs are noindexed; integration metadata is citation-friendly at fixed paths.
