Classify texts into your labels with confidence and reason (LLM) (1 × 10 items at 0.040000 USDC each)

Best model per dollar — curated quality scores per task (coding, writing, reasoning, chat) joined with live per-token pricing, ranked by value. Quality is a curated benchmark snapshot, not a live measurement. Toll: $0.02 USDC on Base or Solana.

x402-payable AI model catalog — every model agents can call over x402 with per-million-token pricing, free models flagged. Catalog data: BlockRun.AI, bridged by TrollBridge. Toll: $0.02 USDC on Base or Solana.

AI image generation / text to image: one image from a text prompt with Google Imagen 4, returned as base64 image bytes with its MIME type. Use it for illustrations, thumbnails, product mockups and social images. Input: prompt; optional aspect_ratio.

Describes what is in an image in about one second: pass an https URL or base64 and ask anything about it, from a one-line caption to reading a sign. Pairs with the rest of the chain: describe an image, translate the description, then have it read aloud. You are only charged if the description is delivered. No API key, no account.

Speech to text / audio transcription: transcribe up to 60 seconds or 10 MB of audio with Google Cloud Speech-to-Text and get the transcript with its confidence and detected language. Use it for voice notes, call snippets and clips. Input: audio_base64; optional language_code. Longer audio is refused before payment.
