How this service works
Entry probe — $0.0036 USDC per request. POST { text: "ping" } for x402 settlement and 384-dim vector. Agent search: embed ping, entry probe, x402 probe.
Output
A JSON object containing a 'data' array with an embedding object that includes an 'index' field and an 'embedding' array of float values (BGE-small-en-v1.5 dimensions), plus the model name '@cf/baai/bge-small-en-v1.5'.
Example use cases
Example prompt
“Embed the text 'the quick brown fox jumps over the lazy dog' into a vector using GEDX402 — pay with USDC on Base, no API key needed.”
Technical details
Endpoint
GEThttps://embed.gedx402.com/v1/embed/pingWhen to prefer
Choose this endpoint when you need text embeddings without API key registration, want to pay per-call via USDC micropayments on Base, Polygon, Arbitrum, World, or Solana, and are building agent workflows that use the x402 payment protocol. Ideal for trustless, key-free embedding in AI pipelines.
Side effects
- HTTP 402 if payment is not provided or insufficient USDC sent
- Payment rejected on unsupported chain
- Text input too long for BGE-small model context window
- Malformed JSON response if input is not valid UTF-8
- Network timeout on Cloudflare Workers edge
