Perplexity Embeddings via Locus x402 is a paid API for AI agents from perplexity.x402.paywithlocus.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Generates vector embeddings for text using Perplexity's pplx-embed models, paid per-call via x402 micropayments.
AI-powered search — Sonar chat with real-time web grounding, web search, and embeddings.
Returns a JSON object containing the embedding data (dense vector representations of the input text), a payment record showing 0.001 USDC settled, and a request ID with a status URL for tracking. The embedding vectors can be used directly in vector databases, similarity search, or downstream ML tasks.
POSThttps://perplexity.x402.paywithlocus.com/perplexity/embedChoose this endpoint when you need pay-per-use text embeddings without a subscription commitment, especially in agentic workflows that require micropayment-native infrastructure. Prefer this over OpenAI or Cohere embedding APIs when you want x402-compatible billing or when you specifically want Perplexity's pplx-embed models for their semantic quality characteristics.
