Bloomberg offers deep programmatic access, but not a public REST API: BLPAPI is a proprietary binary SDK bound to Terminal entitlements, with B-PIPE and Server API for firm-scale feeds. Data License adds a REST surface for enterprise delivery. Everything requires a signed licensing agreement.
Bloomberg Terminal scores A on the API Report Card. Bloomberg offers deep programmatic access, but not a public REST API: BLPAPI is a proprietary binary SDK bound to Terminal entitlements, with B-PIPE and Server API for firm-scale feeds. Data License adds a REST surface for enterprise delivery. Everything requires a signed licensing agreement.
Bloomberg Terminal has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
