How this service works
Crypto, AI, Social Media, Finance, Weather, Tools & more. Pay per call in USDC on Base. No API keys.
Output
Returns an object containing the vector embedding (an array of floating-point numbers) representing the semantic content of the input text, suitable for similarity comparisons, clustering, or storage in a vector database.
Example use cases
Example prompt
“Generate a vector embedding for the text 'sustainable energy solutions for urban environments' so I can use it for semantic similarity search in my vector database.”
Technical details
Endpoint
POSThttps://prime-api-seven.vercel.app/api/ai/embeddingsWhen to prefer
Choose this endpoint when you need to generate text embeddings via a pay-per-call USDC model on Base without managing API keys, especially useful for agents operating in crypto-native or x402 payment ecosystems that need one-off embedding calls without subscription overhead.
Side effects
- Empty or missing query string returns a validation error
- Overly long input text may be truncated or rejected
- Payment failure in USDC on Base results in 402 response blocking the call
- Generic 500 error if the underlying embedding model is unavailable
- Malformed JSON body returns a 400 bad request
