HERE Blob API v2 is one of 71 APIs that [HERE](https://apis.io/providers/here/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Data, Storage, and Blob. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, and an API reference.

HERE Blob API v2 — 10 operation(s) across 4 path(s), OpenAPI 3.0.2 version 2.0.2, harvested verbatim from the HERE developer documentation. The blob service supports the upload and retrieval of large volumes of data from the storage of a catalog. Each discrete chunk of data is stored as a blob (Binary Large Object). Each blob has its own key. You can use keys to store, retrieve, delete and copy blobs. Keys can also be listed. Currently, the blob service supports REST API versions v1 and v2. Version v1 should be used to access versioned, index and stream (if the stream payload is larger than 1MB) layers. Version v2 should be used to access the object store layer. Always pick the proper API version from API Lookup to ensure you get back the correct API version response. Base URL is not fixed: the spec directs clients to resolve it at runtime through the HERE API Lookup Service (https://api-lookup.data.api.platform.here.com/lookup/v1).
