How this service works
Chat, embeddings, OCR, speech-to-text, image editing, image understanding (captioning/Q&A), text-to-speech, translation, writing tools, classification tools, developer tools, local utilities, format/checksum validators, encoding & crypto utilities, date/time calculators, geo/coordinate math, math & finance calculators, novelty tools, and business/social writing generators — 179 endpoints in all, across multiple specialized self-hosted models. Pay per call with crypto — no signup — or get an API key.
Output
Returns a sticker-style image (likely PNG or similar format) depicting the requested subject, generated by a self-hosted AI image model. The image is styled as a sticker (often with clean edges, cartoon-like rendering, or transparent background). With a fixed seed, the result is reproducible.
Example use cases
Telegram sticker pack creation
“Make me a sticker of a grumpy orange cat wearing sunglasses — use seed 7 so I can recreate it consistently.”
Mascot sticker for brand
“Generate a sticker of a friendly robot holding a coffee cup for my tech startup's chat app.”
Fun social media sticker
“Create a sticker of a corgi wearing a party hat, seed 100, for a birthday post I'm putting together.”
Technical details
Endpoint
POSThttps://api.fastapi.online/generate-stickerWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.012 USDC), no-signup sticker image generated from a text prompt. It is ideal for agents that need to produce sticker-style graphics on demand without managing API keys or subscriptions. Prefer it over general image generators when sticker-specific styling (cartoon, clean edges) is desired and crypto micropayment via x402 is acceptable.

- Empty or missing subject returns 422 Unprocessable Entity
