Upload an artifact

POST
/v1/artifacts
curl --request POST \
  --url https://example.com/v1/artifacts \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: multipart/form-data' \
  --form file=@file \
  --form name=example \
  --form contentType=example \
  --form 'tags="example"' \
  --form ownerRunId=2489E9AD-2EE2-8E00-8EC9-32D5F69181C0 \
  --form expectedHash=example

Multipart upload. file part carries the bytes; other form fields carry metadata (name, contentType, tags (JSON), ownerRunId, expectedHash). Framework computes sha256 and returns it in BlobMeta.hash. If expectedHash was supplied and diverges, response is 400 blob-hash-mismatch. Content-type sniffing is NOT performed server-side — the framework trusts the caller.

Parameters

Section titled “Parameters”

Header Parameters

Section titled “Header Parameters”
Idempotency-Key
string
>= 1 characters

Caller-supplied idempotency key. Retries with the same key return the original response byte-identical (per docs/API-ROUTE-CONVENTIONS.md §3.1).

Request Bodyrequired

Section titled “Request Bodyrequired”
Media typemultipart/form-data

Multipart form. file is the byte stream (required). Other fields are optional metadata: name (defaults to file part filename), contentType (defaults to file part MIME), tags (JSON-encoded object), ownerRunId (RunId string), expectedHash (sha256 hex, framework rejects on mismatch).

object
file

string format: binary
name
string
contentType

tags

JSON-encoded Record<string, string> — parsed server-side.

string

string format: uuid
expectedHash

Caller-computed sha256, hex-encoded, lowercase. Framework verifies + rejects on mismatch with blob-hash-mismatch (400).
