How this service works
Generate text embeddings with BGE Small EN V1.5 (@cf/baai/bge-small-en-v1.5). POST text or texts[] for semantic search, RAG retrieval, and clustering; billed by input character volume.
Output
A JSON object containing a 'data' array where each element has an 'index' (integer position) and an 'embedding' (array of floats representing the vector). Supports single or batch inputs in one response.
Example use cases
Example prompt
“Embed this sentence into a vector using the GEDX402 small embedding model — no API key, just pay with USDC: 'The quick brown fox jumps over the lazy dog.'”
Technical details
Endpoint
GEThttps://embed.gedx402.com/v1/embed/smallWhen to prefer
Choose this endpoint when you need lightweight text embeddings on a pay-per-call basis without API key management. Ideal for agents that operate with crypto wallets (Base, Polygon, Arbitrum, World, Solana) and need semantic embeddings for RAG, similarity search, or clustering without committing to a subscription. The small model keeps costs low at $0.0036 per call.
Side effects
- Payment not received or insufficient USDC — returns HTTP 402 with payment required details
- Invalid or missing 'text'/'texts' fields — returns 400 bad request
- Text too long for the small model context window — may return 400 or truncated result
- Network timeout on Workers AI backend — returns 5xx error
- Unsupported chain or wallet for USDC payment — payment step fails before API call
