Pinecone Vector Query via Sovereign x402

Choose this endpoint when you need to perform nearest-neighbor vector search against a Pinecone index without managing your own Pinecone API keys or infrastructure, and you want a pay-per-call model via x402 micropayments. It is ideal for agents that need on-demand semantic search without persistent Pinecone credentials. Prefer the sibling Qdrant endpoint if your vector store is Qdrant instead of Pinecone.

• Pinecone index does not exist or is not accessible — returns an error indicating the index was not found
• Query vector dimension does not match the index dimension — returns a dimension mismatch error
• Invalid or malformed vector values (e.g. non-numeric entries) — returns a validation error
• Missing required body fields such as the query vector or index name — returns a 400 bad request
• Payment not processed — returns a 402 Payment Required before executing the query
• Pinecone service outage or upstream timeout — returns a 503 or timeout error
