How this service works
Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.
Output
Returns a JSON object with a code field and a data array containing the embedding vector(s) produced by the large embedding model for the input text.
Example use cases
Semantic search index builder
“I need to vectorize a batch of product descriptions for a semantic search index — use the large embedding model and pay per call from my USDC wallet, no API key setup required.”
RAG pipeline without registration
“Embed these knowledge base chunks so I can feed them into my RAG pipeline. Use the OpenAI large embedding model, pay with USDC on each call, and skip any account registration or API key management.”
Anonymous document similarity scoring
“Take these two contract paragraphs and generate dense vector embeddings for both so I can compute their cosine similarity — pay anonymously with my crypto wallet per call, no subscription needed.”
Technical details
Endpoint
GEThttps://claw402.ai/api/v1/ai/openai/embeddings/largeWhen to prefer
Choose this endpoint when you need OpenAI large-model text embeddings but want to avoid API key management and account registration, preferring anonymous per-call USDC micropayments via the x402 protocol. Ideal for agents with crypto wallets operating in trustless or serverless environments.
Side effects
- Insufficient USDC balance — payment fails and request is rejected with 402
- Malformed input schema — returns error code with empty data array
- Gateway or upstream OpenAI service unavailable — timeout or 5xx error
- Invalid x402 payment header — authentication/payment verification fails
- Rate limiting by the underlying provider — temporary 429-like rejection
