Authorizations

​
Authorization
string
header
required

Create an API token using sf tokens create or at https://sfcompute.com/account/api-keys.

Headers

​
Idempotency-Key
string | null

Unique key for idempotent transfer creation.

Body

application/json
​
from_capacity
string
required

Source capacity (must belong to the authenticated caller).

Pattern: (cap_[0-9a-zA-Z_-]{1,21})|(sfc:capacity:[a-zA-Z0-9._-]+(:[a-zA-Z0-9._-]+){2,2})
Example:

"cap_k3R-nX9vLm7Qp2Yw5Jd8F"

​
to_capacity
string
required

Destination capacity (must belong to the authenticated caller).

Pattern: (cap_[0-9a-zA-Z_-]{1,21})|(sfc:capacity:[a-zA-Z0-9._-]+(:[a-zA-Z0-9._-]+){2,2})
Example:

"cap_k3R-nX9vLm7Qp2Yw5Jd8F"

​
allocation_schedule_delta
object[]
required

The transfer's allocation schedule as constant-quantity rectangles. If the final entry does not have end_at: null, a zero-quantity unbounded tail is appended automatically.

​
instance_sku
required

Instance SKU the transfer applies to.

Pattern: isku_[0-9a-zA-Z_-]{1,21}
Example:

"isku_k3R-nX9vLm7Qp2Yw5Jd8F"

Response

Capacity transfer accepted.

​
object
string
default:capacity_transfer
required
read-only
Allowed value: "capacity_transfer"
​
id
string
required
Pattern: cxfr_[0-9a-zA-Z_-]{1,21}
Example:

"cxfr_k3R-nX9vLm7Qp2Yw5Jd8F"

​
status
enum<string>
required
Available options:
pending,
executed,
rejected
​
created_at
integer<int64>
required

Unix timestamp.

Example:

1738972800

​
from_capacity
string
required
Pattern: cap_[0-9a-zA-Z_-]{1,21}
Example:

"cap_k3R-nX9vLm7Qp2Yw5Jd8F"

​
to_capacity
string
required
Pattern: cap_[0-9a-zA-Z_-]{1,21}
Example:

"cap_k3R-nX9vLm7Qp2Yw5Jd8F"

​
instance_sku
object
required

Instance SKU the transfer applied to. Carries the SKU's human-readable name when one is registered.

​
allocation_schedule_delta
object[]
required

The transfer's allocation schedule, expanded into constant-quantity rectangles. The final rectangle has end_at: null (the unbounded tail); gaps are represented as explicit zero-quantity rectangles.

​
rejected_reason
string | null

Reason a capacity transfer was rejected.
