AgentRAG
Agent-native retrieval over x402 — send a query and, optionally, source URLs to index: get back ranked, cited chunks. Hybrid retrieval by default (dense vectors + BM25 keyword search, fused and reranked) beats vector-only search on exact tokens (error codes, API symbols, config keys). Pay-on-success: a query that matches nothing settles nothing. Ask $0.008; prepay $1 = 10,000 credits, spent at 80% of the per-op price (20% off). Docs: https://agentx402.ai
