An example result, and what it costs
Every response tells you the credits used, and agents can list each model’s price before spending anything.
Get API key
Ways to integrate
One key and one balance across all four.
REST API
Generate and edit images and video over HTTPS. Sync by default, webhooks when you want them.
QuickstartMCP server
Let Claude, ChatGPT, Cursor, VS Code or Codex call PicX tools directly, signed in with your account.
Connect a clientCLI
picx-cli for the terminal and for agents that shell out. Every command speaks --json.
Install the CLISDKs
Typed clients for JavaScript/TypeScript (picx-ai on npm) and Python (picx-ai on PyPI).
SDK examples
Pay with crypto, then make your first call
From wallet to a generated image, in five steps.
Pick a pack
Sign in and choose a pack on the credits page. Packs start at $5 and need no plan.
Pay from your wallet
Choose a coin and send the payment. Credits land on your account once it confirms. How paying with crypto works.
Create a key and check your balance
Create a key on the keys page. A key spends your account balance, so a new key can use the credits you just bought.
terminalexport PICX_API_KEY=pxsk_your_key curl https://api.picxstudio.com/v1/account/me \ -H "Authorization: Bearer $PICX_API_KEY" # Look for credits.balance in the responseCheck the price
Every model lists its credit price per size. Read it before you spend anything.
terminal# No key needed. Prices are in credits, per size. curl "https://api.picxstudio.com/v1/models?type=image"Generate
The response has the image URL and the credits used. If the generation fails, the credits go back automatically.
terminalcurl -X POST https://api.picxstudio.com/v1/images/generate \ -H "Authorization: Bearer $PICX_API_KEY" \ -H "Content-Type: application/json" \ -d '{"prompt":"a red sneaker on white","model":"gemini-3.1-flash-image-preview","size":"1K","aspect_ratio":"1:1"}' # Returns url and credits_used
Pick a model
Live from GET /v1/models. Credits are for one generation; video is priced per second.
Built for production
Webhooks
Register an endpoint, or bind one to a single job, and get a POST when it finishes.
Webhooks docsAsync polling and SSE
Video returns a job id at once. Poll GET /v1/generations/{id} or stream its events_url.
Video referenceidempotency_key
Retry a request safely. A replay returns the original generation and charges nothing.
QuickstartRefunds on failure
When a generation fails, its credits go back to your balance automatically.
Credit pricing
Rate limits
Limits apply per key. Read your exact values from GET /v1/account/tier, and honor Retry-After on a 429. Rate limit docs

Developer FAQ
Do I need a subscription?
No. A crypto payment buys credits once. Packs start at $5, credits never expire, and nothing renews by itself.
What happens to credits when a generation fails?
Credits are taken when you submit, and they go back to your balance automatically if the generation fails. The failed generation's error_message tells you why.
Can I use this inside my own app?
Yes. An AI feature inside a different product, through the API, is allowed. Use your own key on your own backend. Sharing or reselling API keys, or transferring credits, is not allowed.
Which models can I call, and how do I pick?
GET /v1/models lists every model id with its credit price, and it needs no key. Pass the id as model. Pick by the price at your size and by the output you want. The playground is a quick way to compare them once you have credits.
Can my agent see prices before spending?
Yes. GET /v1/models returns each model's credit price without a key, and the MCP server has the same list as the picx_list_models tool. An agent can read the price and your balance before it spends anything.
How do I pay without a card?
Crypto is the only checkout, so there is no card form at all. 18 coins are accepted, including BTC, USDT, ETH and SOL, with no KYC.
Does crypto auto-renew?
No. Each payment is a single purchase. When you want more credits, you pay again.
Do I need KYC?
No. You need a PicX account and a wallet.
Can an agent spend crypto-funded credits?
Yes. Credits are one balance, so the API, MCP server, CLI and SDKs all spend from it, however you paid.
