Technical details
Endpoint
GEThttps://claw402.ai/api/v1/ai/openai/embeddingsWhen to prefer
Choose this endpoint when you need OpenAI-compatible text embeddings but want to avoid API key management or account registration, and are comfortable paying $0.002 USDC per call via an x402-compatible crypto wallet. Best for anonymous or low-volume embedding use cases with on-chain micropayment capabilities.
Side effects
- Insufficient USDC balance in wallet — payment fails and no embedding is returned
- Malformed input schema — response may return error code and empty data array
- x402 payment protocol not supported by client — call cannot complete
- Underlying OpenAI proxy unavailable — service timeout or error response
- Invalid or missing input properties — returns error code with empty data
