Vectorize one source image into an SVG. The call returns 202 Accepted with a job id; poll GET /images/vectorizations/{id} for the result. The image takes exactly one of image_id, url, or base64 + mime_type. There is no model parameter. Requires the images.transform scope.

SVG is an EU AI Act Art. 50(2) scope-out. An SVG cannot carry a C2PA manifest or an embedded watermark, so vector outputs are delivered unsigned and unwatermarked. Delivery is gated on svg_acceptance — an explicit acknowledgment of this. The acknowledgment is disclosure / audit evidence, not a compliance waiver.

Example: one source per mode

svg_acceptance must be the literal boolean true on every request:

curl -X POST https://api.samsa.ai/public/v1/images/vectorizations \
  -H "Authorization: Bearer $SAMSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image": { "image_id": "123e4567-e89b-12d3-a456-426614174000" },
    "svg_acceptance": true
  }'

curl -X POST https://api.samsa.ai/public/v1/images/vectorizations \
  -H "Authorization: Bearer $SAMSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image": { "url": "https://cdn.example.com/logo.png" },
    "svg_acceptance": true,
    "webhook_url": "https://example.com/webhooks/samsa"
  }'

curl -X POST https://api.samsa.ai/public/v1/images/vectorizations \
  -H "Authorization: Bearer $SAMSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image": { "base64": "iVBORw0KGgoAAAANSUhEUg...", "mime_type": "image/png" },
    "svg_acceptance": true
  }'

The normal (charged) path returns a pending job:

202 Accepted

{
  "id": "a8b9c0d1-2e3f-4a4b-5c6d-7e8f9a0b1c2d",
  "status": "pending",
  "estimated_credits": 5
}

Cost = 5 credits on a miss; 0 on a cache hit. When the source is an image_id you own and a vector result already exists for it, the submit returns 202 with status: "completed" and estimated_credits: 0 immediately — no new job is queued and your organization’s concurrency cap is not consumed.

Acceptance gates

Vectorization has two independent delivery gates, both enforced with no charge on failure:

svg_acceptance must be the literal boolean true. A missing, false, or any other value is rejected 422 svg_acceptance_required.
A current, server-verified ToS/AUP acceptance is also required — the request flag is never trusted as this fact. A missing or stale acceptance is rejected 403 svg_phase1_scope_out_required; accept the current ToS/AUP and retry.

Errors

Status	Code	When
`402`	`insufficient_credits` / `insufficient_team_credits` / `insufficient_unallocated_credits`	The balance this credential can spend is below the job cost. Organizations with at least one active team get the team-aware codes instead of `insufficient_credits` (budget-exempt system organizations excepted). An operational failure inside the deduction can still surface as the generic `insufficient_credits`, whatever the regime.
`402`	`subscription_inactive`	The organization has no usable subscription.
`403`	`missing_scope`	Key lacks the `images.transform` scope.
`403`	`svg_phase1_scope_out_required`	The server-verified ToS/AUP scope-out acceptance is missing or stale (no charge).
`404`	`not_found`	The source `image_id` is unknown, or not owned by the API key’s creator — an image another member of your organization created is a `404` too.
`422`	`validation_error`	Zero or multiple source modes supplied.
`422`	`svg_acceptance_required`	`svg_acceptance` is not the literal boolean `true` (no charge).
`429`	`rate_limited` / `too_many_active_jobs`	Per-key rate window or per-org concurrency cap exceeded.

Authorizations

Authorization

string

header

required

Organization API key as a bearer token: Authorization: Bearer samsa_sk_....

Body

application/json

POST /images/vectorizations body (SAM-821 / S8.9 — Art. 50(2) scope-out).

Vectorize ONE source image into an SVG (Recraft; 5 credits flat). The source is exactly one of image_id (an image in your organization's context), an https url, or base64+mime_type. There is NO model parameter.

SVG is a documented EU AI Act Art. 50(2) scope-out: an SVG cannot carry a C2PA manifest or an embedded watermark, so vector outputs are delivered unsigned. Delivery is therefore gated on svg_acceptance — an explicit acknowledgment that the SVG is an unsigned, unwatermarked scope-out output. This acknowledgment is disclosure / audit evidence, NOT a compliance waiver. svg_acceptance must be the literal boolean true; a missing, false, or any other value is rejected 422 svg_acceptance_required with no charge. Delivery ALSO requires a current, server-verified ToS/AUP acceptance (the request flag is never trusted as that fact); a missing / stale acceptance is 403 svg_phase1_scope_out_required with no charge.

Cost = 5 credits on a miss; 0 on a cache HIT. When the source is an image_id you own and a vector result already exists for it, the submit returns 202 with status: "completed" and estimated_credits: 0 immediately (no new job is queued and the org's concurrency cap is not consumed).

image

PublicImageEditSource · object

required

The source image: exactly one of image_id, an https url, or base64+mime_type.

Show child attributes

svg_acceptance

boolean

required

Must be the literal boolean true: an explicit acknowledgment that SVG (vector) output is an EU AI Act Art. 50(2) scope-out delivered UNSIGNED and UNWATERMARKED. This acknowledgment is disclosure / audit evidence, NOT a compliance waiver. Any other value (missing / false) is rejected 422 svg_acceptance_required with no charge.

Example:

true

webhook_url

string | null

Optional https webhook notified once on terminal status (signed per the webhook signature scheme; see the webhooks docs). On a cache hit the completed event fires immediately.

Example:

"https://example.com/webhooks/samsa"

Response

Successful Response

Shared 202 body for the transform-op submits (SAM-813 / S8 wave).

Every POST /images/<op> returns the async job handle {id, status, estimated_credits}. The initial status is pending (the job is queued), with ONE exception: background-removals and vectorizations answer an owned-image_id cache hit (a ready result already exists for that image) with status: "completed" and estimated_credits: 0 — no new job is queued, the completed webhook event is emitted immediately for a supplied webhook_url, and the result is already available from the op's GET .../{id} endpoint. The other transform ops (img2img, variations, resizes, upscales) always start pending.

string<uuid>

required

The job id — poll the op's GET .../{id} endpoint.

status

enum<string>

required

Initial status: pending (job queued — enter the polling flow), or completed with estimated_credits: 0 when background-removals / vectorizations serve an owned-image cache hit (the result is immediately available).

Available options:

pending,

processing,

completed,

failed,

cancelled

Example:

"pending"

estimated_credits

integer

required

Credits this job is expected to cost — 0 on a cache-hit completed response.

Example:

5
