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 (array of floats) representing the semantic content of the input text, suitable for downstream similarity search, clustering, or retrieval-augmented generation tasks.
Example use cases
Example prompt
“Generate a vector embedding for this text: 'The quick brown fox jumps over the lazy dog' — I need it for a semantic similarity comparison.”
Technical details
Endpoint
POSThttps://nexus-api-peach-nine.vercel.app/api/ai/embeddings?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need pay-per-call text embeddings with no API key setup, especially in agentic workflows on Base where USDC micropayments are preferred over subscription billing. Good for one-off embedding calls or prototyping semantic search pipelines without committing to a managed embedding provider.
Side effects
- Empty or missing query string returns a validation error
- Extremely long input text may be truncated or rejected
- Payment failure in USDC on Base blocks the request
- Server-side model error returns a generic 500 response
- Malformed JSON body returns a 400 bad request
