About

An open-data API for U.S. addresses. Still early.

FastOpenData is a solo project aiming to turn public CSVs, shapefiles, and government FTP servers into a single, clean API. Right now that's mostly a goal and some real ETL code — not a finished product.

01

Time to value beats everything.

If a developer can't get a useful response inside thirty seconds, we've failed. No SDKs to wrap, no schemas to learn, no auth flows to debug.

02

Public data should stay public.

We don't relicense it, we don't lock it behind enterprise tiers, and we don't enrich it with proprietary signals. The dataset is the dataset.

03

Honesty over hype.

If something isn't built yet, this site should say so. Prototypes get labeled as prototypes, and mockups get labeled as mockups.

FastOpenData is a solo project. There's no company, no funding round, no team behind it — just one person building an ETL pipeline and API for public U.S. address, geographic, and demographic data, in the open, incrementally.

The idea is straightforward: public data — Census, TIGER, OpenStreetMap, and more — is scattered across CSVs, shapefiles, and government FTP servers, and every project that wants it ends up rebuilding the same address-to-tract joins from scratch. The goal here is to build that join once, properly, and expose it as a single clean API.

Today, that goal is partly built: the geocoding endpoint works, and the ETL pipelines that ingest Census, TIGER, and OpenStreetMap data already exist in the codebase for a separate graph-processing project. Wiring that enrichment into this API is the next phase of work, not a finished feature.

This site will get more honest, not less, as the project matures — pages will move from "planned" to "live" as the work actually lands.

One person, opinionated about ETL.
