Crosspeel: The API Independence Test
A research tool that compares machine-payable API endpoints for shared infrastructure hidden behind separate brands.
Field notes
The project maintains a corpus that separates endpoints actually paid for and measured from those called at least once. Its homepage reports 122 observed endpoints alongside 1,265 screened endpoints, with the latest probe run dated 2026-09-04. The comparison records low-level response details such as certificate issuers, header order, field names, error strings, timing, and price. No clusters are published yet, so the public evidence currently describes the method and collection process rather than a finding.
