Querying USAspending for Federal Contract Awards With a POST Search and No API Key
USAspending publishes every federal award the United States government makes, and the API needs no key, no registration and no authorization header. That combination is rare enough on government data that it is worth saying twice.
The thing that stops most people is the shape of the request. The interesting endpoints are POST, the body is a nested object, and a wrong field name gets you a 400 with little explanation. Here is the working version.
Reading the Launch Library API for Rocket Launch Schedules Without a Key
The Space Devs run Launch Library, a REST API covering orbital and suborbital launches worldwide, past and upcoming. No key, no signup, and a forward schedule that currently runs to 369 launches.

Pagination Strategies for Large Datasets and Why Offset Pagination Fails
Offset pagination — the pattern where a consumer requests a page by specifying how many records to skip — is the default choice for most APIs because it maps naturally to SQL’s LIMIT and OFFSET clauses and allows consumers to request any page directly by number. It is also the pagination strategy that fails most visibly at scale and produces the most confusing behavior when underlying data changes between page requests.
