Making API evolution safe, observable, and lean by default
Founded in 2025, Trezko grew out of a recurring failure mode in fast-moving engineering organizations: backend services ship daily, OpenAPI documentation lags behind reality, and downstream mobile or partner integrations break silently from unannounced field mutations.
At the same time, unchecked ORM serialization bloats JSON responses with sparse `null` fields and internal metadata—driving up p99 latency and cloud NAT/CDN egress bills. Trezko solves both problems in a single zero-PII structural pipeline.
Built on cloud-native streaming primitives
Designed for high-throughput ingestion, sub-second contract diffing, and automated anomaly classification.
Stateless Edge Ingestion
Regional Cloud Run ingestion endpoints terminate TLS, validate workspace API tokens, and batch structural AST hashes with horizontal autoscaling.
Columnar Contract Store
Partitioned analytical storage indexes billions of path-level type observations, enabling instant historical drift queries across 365-day windows.
Semantic Drift Triage
LLM-assisted release summaries explain complex nested contract diffs on pull requests and suggest backward-compatible migration shims.
2026–2027 Engineering Roadmap
We build in partnership with backend, platform, and SRE teams. Have a protocol or CI requirement? Reach out directly.
