Perigon vs Guardian Open Platform: overview
Perigon
Perigon is an Austin, Texas startup founded in 2022 by Joshua Dziabiak and Josh Rickel, backed by a $5 million seed round that LiveOak Ventures led in February 2024. For developers its main draw is that the pricing page tells you what you will pay: Individual at $25 a month for personal use, Startup at $250 with limited commercial rights, and Commercial at $1,250 with real-time data, an SLA and SSO. Every tier returns enriched articles with entities, topics, summaries and story clusters from 230,000+ sources (per company website; independently unverifiable), and Monitors let you save a query and get matches on a schedule. Plan for the delay: below Commercial, data lags by an hour unless you pay for the real-time add-on.
Guardian Open Platform
The Guardian's Open Platform exposes the same content API that powers the Guardian's websites and apps. A free developer key returns full article bodies with tags and sections back to 1999, and commonly reported limits are about 5,000 calls a day and 12 a second. The key is for non-commercial projects; commercial use needs a deal with Guardian News & Media. Developers like it for teaching because the tagging is consistent and the responses are predictable, which makes it a good dataset for NLP exercises. The obvious limit is that every article comes from one newspaper.
