BioSamples Lookup: One Sample Record by Accession

biosamples/sample-lookup

Returns one public BioSamples record by accession (SAMN, SAMEA or SAMD followed by digits): name, taxon id, status, release and update dates, the characteristics map and external references. A private sample answers a non-retryable validation error; an unknown accession answers a provider error with an empty upstream body. EMBL-EBI BioSamples data, served by Eden Engine; not an official EMBL-EBI product.
