How this service works
Text embeddings (768-dim). Send {"input": "text"} or {"input": ["a","b"]}.
Output
Returns a 768-dimensional floating-point vector (or array of vectors for batch input) representing the semantic content of the input text, suitable for similarity comparison, nearest-neighbor search, or downstream ML tasks.
Example use cases
Semantic search over document corpus
“Take these 10 product descriptions and embed them all so I can store them in my vector database for semantic search later.”
Duplicate detection in support tickets
“I have two customer support messages — embed both of them so I can compute their cosine similarity and check if they're asking the same thing.”
Clustering user feedback
“I've got a batch of 50 user survey responses. Can you embed each one so I can run k-means clustering to group similar feedback together?”

Endpoint
POSThttps://released-mph-process-lib.trycloudflare.com/v1/embed?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, affordable 768-dimensional text embeddings via a simple REST call with per-call micropayment pricing ($0.005 USDC). Ideal for agents that need to embed text on-the-fly without managing API keys or subscriptions, especially in agentic pipelines using the x402 payment protocol.
Side effects
- Empty or null input string returns an error
- Input array exceeds maximum batch size limit
- Network timeout if input text is extremely long
- Payment failure via x402 protocol blocks the request
- Malformed JSON body returns 400 error
