Why teams call Grok Imagine 1.5 (grok-imagine-1.5-apimart) through APIMart

• One key, entire catalog. The same https://api.apimart.ai/v1 base URL and Authorization header reach Grok Imagine 1.5 (grok-imagine-1.5-apimart) and 300+ other image, video and language models — switch the model field, not your client.
• $1 minimum, pay as you go. No subscription and no prepaid plan to size up front: top up from $1 and spend it on calls. There is no free quota to burn through first, so the price in this table is the price you pay.
• The charge comes back in the response. Every call reports the amount billed (cost / credits_cost), so a spend number is read per call instead of guessed at month end.
• Async by design. Submit, take the task_id, poll GET /v1/tasks/{id} — batching and retries are ordinary queue work, not a bespoke integration.

Six Grok Imagine API recipes with the output each one produced, the aspect ratio, the measured cost per image, and the request shape for both text-to-image and reference-based editing.

• Model: grok-imagine-1.5-apimart
• Recipes: 6 (machine-readable in data/prompts.json, table in PROMPTS.md)
• Measured cost of the whole set: $0.09

What Grok Imagine rewards in a prompt

Grok Imagine responds well to scene-first prompts: describe the world, then the camera. Across the recipes here, three patterns did the work:

1. World before subject. "Neon-lit underpass, rain on asphalt" before "a motorbike" gives the lighting for free.
2. Two colour anchors. Naming a palette pair ("magenta and cyan rim lights", "warm sunset blocks") keeps a series visually consistent, which matters when you generate variations with n=10.
3. State the output use. "Poster", "commercial product photography", "concept art" pull different framing habits out of the model.

Prompt structure cheat-sheet

Slot	What to write	Example
World	environment and weather	neon-lit underpass, rain on asphalt
Subject	one hero element	a parked motorbike
Light	sources and colour anchors	magenta and cyan rim lights
Camera	distance, lens, mood	cinematic still, shallow depth of field
Use	what the image is for	poster / product shot / concept art

The gallery

Each row is one API call: output, category, ratio, reported cost and the exact prompt.

Output	Recipe	Ratio	Cost	Prompt

	Food	4:3	$0.015	Gourmet chocolate dessert with gold leaf on a dark ceramic plate, moody side light, shallow depth of field, fine dining food photography

Run a recipe yourself

export APIMART_API_KEY=...
python examples/run_recipes.py --dry-run                 # list the recipes, no network
python examples/run_recipes.py --limit 2                 # generate two of them
python examples/run_recipes.py --category "Food"         # filter by category

Result links expire, so store the outputs; the completed task carries cost for reconciliation.

What that costs at scale

Spend	Cost
100 images	$1.50
1000 images	$15.00
10000 images	$150.00

Linear at the observed per-unit rate, no volume discount assumed. Snapshot 2026-09-17; re-check the live table before committing a budget.

First-call troubleshooting

Symptom	Likely cause	Fix
401 / invalid api key	key missing, truncated, or a stray newline pasted into the header	Re-copy it from the console; the header is Authorization: Bearer $APIMART_API_KEY
balance / credit error	the account has no balance	Top up from $1 in the console — there is no free quota to fall back on
429	concurrent requests on one key	Back off, then retry the same request with the same Idempotency-Key
400 / model not found	wrong route for the id: the per-unit alias needs its version, the official id must not send one	Copy the exact model value from the route table above
task ends failed	prompt rejected by the filter, or a reference image URL expired	Re-submit with a new Idempotency-Key and re-host the reference image
result URL stops working	result links expire	Download the file as soon as the task reports completed

FAQ

What is the Grok Imagine model id?

grok-imagine-1.5-apimart (alias grok-imagine-1.5-ext). The same endpoint also documents grok-imagine-image and grok-imagine-image-quality.

Can I get several variations in one call?

Yes — this route accepts n between 1 and 10, so exploring a scene costs one request instead of ten.

How do I edit an existing image?

Send 1–5 publicly reachable image URLs in image_urls and describe what to preserve and what to change. Local files must be uploaded to public storage first.

Are these recipes free to reuse?

The prompt text is MIT licensed; the outputs and any marks inside them are your responsibility, and vendor terms still apply to commercial use.
