Every source,
one API key.

Official APIs, public registries and statistics offices, reached the same way as a scrape: one key, one credit wallet, one error shape. Every response carries the licence and the attribution the source asks for, so you can use what you get.

Named after the library of Pergamon, whose scribes gave us parchment and kept collecting.

How it works

Three parts, no SDK.

Discover

GET /v1/data lists every live provider, its capabilities, the parameters each one takes and what it costs. It is free to call.

GET /v1/data

Call

One GET per capability. Required parameters come from the catalog, so there is nothing provider-specific to learn.

GET /v1/data/npm/package
  ?name=react

Attribute

Every response carries a provenance block: the source, the exact upstream URL, the licence and the attribution line to display.

  "Source: npm registry"

[ 03 / 03 ] · licensing

Licensing

We read the terms first.

A source only appears here once someone has read what it permits. That answer ships with the data.

The licence travels with the response

Not a page in our docs: the actual licence text and attribution line for that provider, on every call, so you can satisfy it programmatically.

Nothing ships un-reviewed

A provider whose terms nobody has read is not reachable. There is no default-on path onto this page.

Caching follows the licence

Where a source says do not retain, we do not cache. Where it is public domain, we cache hard and you get the latency back.

Want a source that is not here? Tell us which one. The catalog grows by request.

Every source,one API key.
