Ask an LLM
“How do I write or overwrite data in a volatile layer?”
“Can I send a digest so the server verifies a volatile blob upload?”
Tell an agent
Publish data to handle {dataHandle} in volatile layer {layerId}.

Ask an LLM
“How do I upload a very large blob to a data handle in parts?”
“Where do I get the URLs for the later multipart steps of a data handle upload?”
Tell an agent
Start a multipart upload for data handle {dataHandle} in layer {layerId} as {contentType}.
Begin uploading blob {dataHandle} to {layerId} in multiple parts.
GET /layers/{layerId}/data/{dataHandle}/multiparts/{multiPartToken} Check a data handle upload's status · Gets the status of a multipart upload #
Ask an LLM
“Has the multipart upload for my data handle finished?”
“Can I see the status of a data handle multipart upload before it completes?”
Tell an agent
Get the status of upload {multiPartToken} for data handle {dataHandle} in {layerId}.
Tell me whether multipart {multiPartToken} of blob {dataHandle} on {layerId} is done.
PUT /layers/{layerId}/data/{dataHandle}/multiparts/{multiPartToken} Finish a data handle multipart upload · Completes a multipart upload #
Ask an LLM
“How do I finalize a data handle upload once all its parts are sent?”
“What happens after the last part of a data handle blob is uploaded?”
Tell an agent
Complete upload {multiPartToken} for data handle {dataHandle} in {layerId}.
Finalize blob {dataHandle} on {layerId} from parts {parts} of upload {multiPartToken}.
DELETE /layers/{layerId}/data/{dataHandle}/multiparts/{multiPartToken} Cancel a data handle multipart upload · Cancels a multipart upload #
Ask an LLM
“How do I abort a partly finished upload for a data handle?”
“Can I cancel a data handle multipart upload that already completed?”
Tell an agent destructive · confirm first
Cancel upload {multiPartToken} for data handle {dataHandle} in {layerId}.
Abort multipart {multiPartToken} of blob {dataHandle} on layer {layerId}.
POST /layers/{layerId}/data/{dataHandle}/multiparts/{multiPartToken}/parts Upload one part of a data handle blob · Uploads a part #
Ask an LLM
“What is the minimum part size for a data handle multipart upload?”
“How are the parts of a data handle upload numbered?”
Tell an agent
Upload part {partNumber} of upload {multiPartToken} for data handle {dataHandle} in {layerId}.
Send part {partNumber} ({Content-Length} bytes) of blob {dataHandle} on {layerId}, upload {multiPartToken}.
