What Bluefield is
Bluefield is a web data API. Give it a URL and it returns clean, structured data your code can use immediately. It handles headless browser rendering, JavaScript execution, bot detection, and PDF parsing so you do not have to.
The API surface covers everything from a single page scrape to recursive site crawls, structured LLM extraction, batch jobs, and web search. Every operation is credit-based, and the free tier is available without a credit card.
Two features distinguish Bluefield from a commodity scraping service. The first is watch mode. The second is signed, offline-verifiable captures on every live fetch — one-shot and watch mode alike.
Watch mode
Subscribe to any URL and receive a webhook when its content changes in a meaningful way. The adaptive polling engine learns each page's change cadence and adjusts check frequency automatically.
Attestation
Every live fetch returns a signed provenance manifest. You can verify authenticity and timestamp offline without trusting our servers.
Run it yourself
A Docker image is available so you can run Bluefield in your own infrastructure. Requires Postgres and object storage. Enterprise plans include deployment support.
