What it does
Blixtworks exposes 63 pay-per-call tools for vision, text, data, web, and blockchain tasks. Agents call tools via MCP and pay in USDC on Base using x402, with no accounts or API keys required—payments settle directly to self-custody wallets.
- Extract text from images via OCR for document processing workflows.
- Generate image captions or categorize images with custom label sets for content moderation.
- Retrieve CLIP embeddings for image similarity matching or clustering tasks.

Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
