PRIDE Archive API
Public base: https://www.ebi.ac.uk/pride/ws/archive/v3 (no key). Use the current OpenAPI schema.
| GET path | Purpose |
|---|---|
/projects?page=0&pageSize=5 | List projects |
/search/projects?keyword=alzheimer&page=0&pageSize=5 | Search projects |
/projects/PXD010000 | Retrieve project metadata |
/projects/PXD010000/files?page=0&pageSize=10 | List project files |
/projects/PXD010000/files/count | File count |
/files/{fileAccession} | File details |
/projects/count | Project count |
/projects does not implement keyword search. Use /search/projects; its filter syntax is field==value, with fields from the current search/facet schema. Search supports sortFields, sortDirection, and dateGap. Pagination uses zero-based page and pageSize (documented default 100). List/search/file-list responses are JSON arrays, not a universal results envelope. A single project is an object; inspect actual keys before parsing.
The Archive API does not expose the previously suggested /spectra, /peptideevidences, or /proteinevidences routes. For identified molecules and spectra, use the linked PRIDE analysis resources or download the project files. Retain PXD accession, assay provenance, organism and submission/publication dates; submitted data alone do not establish peptide/protein identification confidence.
