data-freshness

Data freshness verification for AI agents. Probes endpoints for cache staleness, latency, TLS health, and content changes. CLI + MCP server + HTTP API.

Use API caching in API Gateway to cache your responses. Reduce calls made to backend and improve latency of requests to your API

A vendor-neutral OpenTelemetry semantic convention for data staleness (data freshness), plus a Python SDK and Go Collector components.

Learns each dataset's own arrival distribution instead of applying one fixed freshness rule to everything: 86% fewer false alarms than an "alert if not loaded by 07:00" rule at 99.4% detection, plus lineage-aware alert suppression and per-dashboard trust scores. DuckDB, Python, Airflow-shaped, zero cloud credentials.

Declarative, scheduled refresh pipeline for map data: pull GeoJSON/JSON/CSV from HTTP APIs, files or SQL, transform and validate it, detect real changes with an order-stable content hash, and emit a freshness manifest plus a stale-data badge. Includes a composite GitHub Action that rebuilds only when the data moved.

Validate downloaded partner CSV/Parquet feeds locally after SFTP/S3, then alert on missed rolling receipts.
