# JevSift > JevSift is a citation inspection API for financial and research agents. It checks a model claim against retrieved source passages and returns 通过 (pass), 待核 (flag), or 拦截 (block). Release rules live on the server; the model does not grant pass/block itself. Website: https://jevsift.com API: https://app.jevsift.com/v1 MCP: https://app.jevsift.com/mcp Docs: https://jevsift.com/docs Pricing: https://jevsift.com/pricing Skill: https://jevsift.com/skill.md OpenAPI: https://jevsift.com/openapi.yaml ## What it does JevSift inspects whether a claim is supported by provided sources (entity, numbers, time window, accounting basis). It is auxiliary review, not a compliance or investment conclusion. It does not retrieve filings for you; callers pass sources they already have. ## How to use 1. Get an API key at https://jevsift.com/pricing (Free: 500 checks/month after email signup; Pro: $9/month, 10,000 checks). 2. Call MCP tool inspect_citation, or POST https://app.jevsift.com/v1/inspect with pack citation_v1, claim, and sources. 3. Check remaining quota with MCP get_usage or GET https://app.jevsift.com/v1/usage. ## Actions | Code | Chinese | Meaning | |------|---------|---------| | pass | 通过 | Safe to publish | | flag | 待核 | Needs a human look | | block | 拦截 | Do not present as verified | ## Optional - Do not treat the model's own answer as a source. - Do not invent pass/block without calling the API.
