Relaystation Baton Vector Query

Use this endpoint when you need fast, pay-per-query semantic similarity search over a persistent, named vector store (baton) managed by Relaystation — especially in RAG pipelines, semantic deduplication, or recommendation systems where the index is already populated via Relaystation's batch-write endpoint. Prefer this over general-purpose vector DB APIs when operating within the Relaystation baton ecosystem with x402 micropayment billing.

• Baton ID not found — returns 404 if the baton doesn't exist or hasn't been initialized
• No vectors indexed — returns empty results if the baton has no embeddings written yet
• Malformed input — missing or wrong-type 'input' body returns 400 validation error
• Dimension mismatch — query vector dimensionality differs from indexed vectors causes an error
• Insufficient x402 payment or expired credit — returns 402 Payment Required
• Rate limiting or quota exceeded — returns 429
