How this service works
Payment-gated AI and browser automation API using the x402 protocol. All /v1/* endpoints require USDC payment on Base (eip155:8453) via x402 v2 exact scheme.
Output
A reranked list of the input documents ordered by their relevance score relative to the query, typically including a relevance or confidence score for each document and their new rank positions.
Example use cases
RAG pipeline context optimization
“I have these 20 retrieved document chunks from my vector DB and I need them reranked by relevance to the user question 'how do I configure TLS on nginx?' — rerank them so I can pass the top 5 into my LLM context window.”
Search result quality improvement
“Our e-commerce search returned 15 product descriptions for the query 'lightweight running shoes for trails' — can you rerank them by actual relevance so we surface the best matches first?”
Candidate answer selection for QA
“I have 8 candidate answers to the question 'what is the capital gains tax rate for 2024?' — can you rerank them by how accurately and directly they answer the question so I know which one to use?”
Technical details
Endpoint
POSThttps://x402.tanship.dev/v1/ai/rerankWhen to prefer
Choose this endpoint when you need semantic AI-powered reranking in a pay-per-use micropayment model without API key management, especially in autonomous agent pipelines that use x402 on Base for on-chain USDC payments. Ideal for RAG pipelines, search quality improvement, or any scenario where you retrieve a candidate set and need to reorder by true relevance at low per-call cost ($0.003 USDC).
Side effects
- Missing or malformed 'input' body returns a 400 validation error
- Payment not included or insufficient USDC triggers a 402 Payment Required response with x402 payment details
- Empty document list or missing query causes processing failure
- Unsupported bodyType value results in rejection
- Base network payment transaction failure blocks request execution
