How this service works
Generate a text embedding vector using OpenAI text-embedding-3-small (1536 dimensions). Ideal for semantic search, RAG, and clustering. No API key needed; pay per call via x402. Text capped at 32k chars.
Output
A 1536-dimensional float vector (array of numbers) representing the semantic content of the input text, suitable for similarity search, clustering, or RAG retrieval pipelines.
Example use cases
Example prompt
“Turn this product description into a 1536-dim embedding vector so I can store it in my vector database for semantic search: 'Lightweight waterproof hiking boots with anti-slip soles and breathable mesh lining, ideal for trail use.'”

Endpoint
POSThttps://agent402.tools/api/embedWhen to prefer
Choose this endpoint when you need a high-quality 1536-dim embedding from OpenAI's text-embedding-3-small model without managing your own OpenAI API key, and you want to pay per call via x402 micropayment. Ideal for agents building RAG pipelines, semantic search, or clustering on the fly without provisioning credentials.
