Use HERE: its Blob API v2 By Key API lets you check that a key exists and read its metadata in a single step (HEAD /layers/{layerId}/keys/{key}). HERE also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.
- How can I tell whether a key exists in an object store layer without downloading it?
- Can I get an object's metadata like size and type without its content?
Say it to your AI assistant
- Check whether key {key} exists in layer {layerId}.
- Fetch the metadata only for key {key} on layer {layerId}.
