Verify API
Email verification API — single-address real-time validation and asynchronous CSV batch verification, sold as Intelligent Verification. OWNERSHIP: this API is served from api.lastbounce.com rather than a terminus.com or demandscience.com host because Verify is the renamed Lastbounce product; the provider's own reference states the environment URL format is https://.lastbounce.com/, and the article is published in the DemandScience Help Center whose product-rename set (Lastbounce → Verify, Klarity → Audience Builder, Email Experiences → Signature Ads) is documented in lifecycle/terminus-lifecycle.yml. It is a sibling product to the Terminus ABM Platform under the merged DemandScience entity this repo profiles, NOT a Terminus-branded API — recorded as its own entry so it is never conflated with the ABM Platform API. It is the only API of this provider with a public reference: endpoints, the x-api-key header, the error envelope and the full result-code vocabulary are all published, though no OpenAPI is served (the article offers "a copy of the full API documentation" on request). Operations: POST /api/singleEmail/validate, POST /api/batch/validation, POST /api/batch/{jobId}/status, GET /api/file/download/{jobId}. Metered in prepaid credits, one per verification.
