How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

Output

A JSON array of objects each containing an 'index' (position in the original contexts array) and a 'score' (0-1 relevance score), sorted by relevance to the query. Only the top_k results are returned.

Example use cases

Example prompt

“From these 10 candidate paragraphs I retrieved, rerank them against the query 'how does photosynthesis work' and return the top 3 most relevant ones.”

Endpoint

When to prefer

Use this endpoint when you need a lightweight, no-API-key reranking step in a RAG or search pipeline and want to pay per-call with USDC on a blockchain network. Ideal for agents that have already retrieved candidate passages and need to reorder them by semantic relevance before presenting to the user. Prefer over embedding-based similarity if you want a dedicated cross-encoder-style reranking model.

Side effects

Empty or missing 'query' parameter returns error or undefined behavior
Empty 'contexts' array returns empty results
top_k larger than contexts length may return fewer results than requested
Payment failure on all supported chains (Base, Polygon, Arbitrum, World, Solana) results in 402 response
Malformed context objects missing 'text' field may cause errors
Very long passages may hit token limits of the underlying model
