SDK examples

Because the API is OpenAI-images compatible, any OpenAI SDK works — just point its base URL at Pixly.

Python (openai)

from openai import OpenAI

client = OpenAI(
    api_key="<YOUR_API_KEY>",
    base_url="https://api.genframeai.com/v1",
)

# text to image
res = client.images.generate(
    model="gemini-2.5-flash-image",
    prompt="a serene mountain lake at dawn",
    size="1024x1024",
)
print(res.data[0].url)

# image to image / edit
edit = client.images.edit(
    model="gemini-2.5-flash-image",
    prompt="replace the background with snowy mountains",
    image=open("source.png", "rb"),
    size="1024x1024",
)
print(edit.data[0].url)

Node.js (openai)

import OpenAI from "openai";
import fs from "node:fs";

const client = new OpenAI({
  apiKey: "<YOUR_API_KEY>",
  baseURL: "https://api.genframeai.com/v1",
});

// text to image
const res = await client.images.generate({
  model: "gemini-2.5-flash-image",
  prompt: "a serene mountain lake at dawn",
  size: "1024x1024",
});
console.log(res.data[0].url);

// image to image / edit
const edit = await client.images.edit({
  model: "gemini-2.5-flash-image",
  prompt: "replace the background with snowy mountains",
  image: fs.createReadStream("source.png"),
  size: "1024x1024",
});
console.log(edit.data[0].url);

Note: the base URL must include /v1. Images come back as data[].url (some models return b64_json).

Credits & billing

Calls are billed in credits, deducted from your balance.
gemini-2.5-flash-image costs 5 credits/image; the actual deduction is authoritative.
Credits are deducted after a successful generation.
Insufficient balance returns 402. Top up on the pricing page.

Rate limits

Each API key is rate-limited. On a 429, back off exponentially and retry.

Error handling

Status	Meaning
400	Bad request (missing model/prompt, etc.)
401	Missing or invalid API key
402	Insufficient credits
429	Rate limited — retry later
500	Server error

Error response shape:

{ "error": { "message": "insufficient credits", "type": "invalid_request_error" } }
