EPFL GETprime qPCR Primer API

GETprime is a public, unauthenticated HTTP service from EPFL's Gene Expression Core Facility that returns ranked, validated qPCR primer pairs for a gene identifier, organism and Ensembl release. It is documented by EPFL at /api_documentation and was verified live on 2026-08-19 with a successful POST. Recorded here because it is the kind of surface this catalog usually misses: a real, institution-operated research API that lives outside the news/events/repository estate. One correction to the published documentation — the documented JSON request body returns HTTP 500 against the live service; application/x-www-form-urlencoded succeeds.

  title: EPFL GETprime API
  description: GETprime is an EPFL-operated public web service from the Gene Expression Core Facility (GECF) that returns validated, genome-wide qPCR primer pairs. It is one of the few institution-operated, publicly documented and unauthenticated APIs EPFL runs outside its news and events estate. EPFL publishes no OpenAPI for it; this document is derived from the published API documentation at https://getprime.epfl.ch/api_documentation and from a live, successful POST executed on 2026-08-19. Note that the documentation shows a JSON request body, but only application/x-www-form-urlencoded was observed to succeed against the live service; a JSON body returned HTTP 500.
