aid: ethyreal-bio name: Ethyreal Bio description: 'Ethyreal Bio is a Cambridge, Massachusetts clinical-stage biotechnology company founded in 2024 and headquartered at 700 Technology Square, developing precision therapies for thyroid diseases with high unmet need. It emerged from stealth on 10 June 2026 with $101 million in combined Series A and Series B financing — the Series A co-led by Atlas Venture and Medicxi alongside Nandi Life Sciences and Checkpoint Capital, the Series B led by Avoro Capital. Its lead program ETHY-001 is a monoclonal antibody that blocks autoantibody-mediated activation of the thyroid stimulating hormone receptor (TSHR), the shared pathogenic driver of Graves'' disease and thyroid eye disease; it is formulated for subcutaneous administration with half-life extension technology for infrequent dosing, and first-in-human trials were planned for the second half of 2026. Ethyreal Bio publishes no developer program, no product API, no SDKs and no OpenAPI definition of its own. The only machine-readable surface on ethyrealbio.com is the WordPress REST API (wp/v2) that the company website exposes at /wp-json/, which serves its press releases, corporate pages, leadership and board-of-directors profiles, media library, taxonomies and site search as JSON. The OpenAPI documents in this repository were derived mechanically by API Evangelist from that route-discovery descriptor.' url: https://raw.githubusercontent.com/api-evangelist/ethyreal-bio/refs/heads/main/apis.yml x-type: company x-source: harvest:secondary-market x-tier: profiled x-tier-reason: enrichment-pipeline image: https://www.ethyrealbio.com/wp-content/uploads/logo.png specificationVersion: '0.23' created: '2026-08-12' modified: '2026-08-12' tags: - Company - Biotechnology - Pharmaceuticals - Life Sciences - Drug Discovery - Clinical Trials - Immunology - Endocrinology - Antibodies - Rare Disease - Health - Content apis: - aid: ethyreal-bio:ethyreal-bio-comments-api name: Ethyreal Bio Comments API description: The Comments API from Ethyreal Bio — 7 operation(s) for comments on the ethyrealbio.com WordPress REST surface.
