402utils Text Embedding via Cloudflare Workers AI

API ↗

402utils Text Embedding via Cloudflare Workers AI is a paid API for AI agents from 402utils.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-13, last successful call 2026-07-17).

Converts one or a batch of text strings into float vector embeddings using Cloudflare Workers AI BAAI models, for use in semantic search, RAG pipelines, and similarity comparisons.

How this service works

Text → vector embeddings via Cloudflare Workers AI. Send {text} or {texts[]} (≤20, each ≤4000 chars); returns one float vector per input. Default model @cf/baai/bge-m3 (1024-dim, multilingual). The model is named in the response — embeddings only compare within the same model. Completes the RAG chain: readability → chunk → embed, no OpenAI account. Cosine-compare the vectors yourself. Unavailable model/binding → 503, not billed.

Output

Returns one float vector per input text (1024 dimensions for the default bge-m3 model, fewer for smaller models), along with the model name used. Multiple texts in a batch return a corresponding array of vectors. If the model or Cloudflare binding is unavailable, returns 503 and the call is not billed.
