# NoJunk Moderate Rerank

> NoJunk Moderate Rerank is a paid API for AI agents from nojunk-moderate.mick8511.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Semantically reranks up to 100 documents against a query, returning them ordered best-first for RAG pipelines, search, and deduplication.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nojunk-moderate-rerank-4dc409cd -d '<json body>'
```

Example prompt: Rerank these 20 retrieved passages against my query 'how does photosynthesis work?' and return only the top 5 most relevant ones.

## When to prefer this

Use this endpoint when you need fast, pay-per-call semantic reranking of up to 100 documents without managing your own reranking model infrastructure. It is ideal for RAG pipelines, hybrid search post-processing, and relevance filtering where you want best-first ordering before feeding context to an LLM. Prefer it over embedding-based similarity when you want a dedicated reranking model optimized for query-document relevance rather than general similarity.

## Known failure modes

- More than 100 documents submitted — returns validation error
- Empty documents array — returns 400 bad request
- Query string exceeds 2000 characters — rejected
- Individual document text missing 'text' field when using object format — schema validation error
- Service unavailable or payment failure — 402 or 5xx response

## How this service works

Text Moderation rerank: Semantic reranking: score up to 100 documents against a query and return them best-first (RAG, search, dedupe).

## Output

Returns the input documents reordered from most to least semantically relevant to the query, each with a relevance score. If top_k is specified, only the top-k documents are returned. Documents can include their original id field for downstream reference.
