Higgsfield Soul on Sume: half a cent per image, batches of 1 or 4

higgsfield-soul is the cheapest image row in Sume's catalog: $0.005 at 720p and $0.0075 at 1080p per image. It is text-to-image only (zero input_references), and the number of images per request is 1 or 4, not a free 1 to 4 range.

Price by tier and batch

A four-image call

Ask for four when you want a spread, since a batch of four costs four singles.

import os, requests

r = requests.post(
    "https://api.sume.com/v1/images",
    headers={"Authorization": f"Bearer {os.environ['SUME_API_KEY']}"},
    json={
        "model": "higgsfield/soul",
        "prompt": "Portrait of a skateboarder in golden hour light, film grain",
        "n": 4,
        "resolution": "720p",
    },
    timeout=60,
)
print(r.status_code)
body = r.json()
if r.status_code == 200:
    for item in body["data"]:
        print(item["url"])
else:
    print(body)

Where it fits

Use Soul for mood boards, prompt exploration and thumbnails you will not edit. When you need to edit a photo, keep text legible, or return a transparent PNG, switch to a row that lists references, quality tiers or the background field.

Sizes depend on the tier; read the live resolution descriptor from GET /v1/images/models rather than hard-coding it.

Budget view

• 10,000 images at 720p cost $50.00.
• The same 10,000 at 1080p cost $75.00.
• Use n: 4 for a spread and n: 1 for a single; other counts are not listed for this row.
• Read GET /v1/images/models/{model_id}/endpoints for the live pricing line before a large run: prices are catalog data and can change.
