# Citiview Answer Grader

> Citiview Answer Grader is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-14).

## 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 citiview-answer-grader-6679a499
```

Example prompt: Before you send that answer, grade it against the original question — 'What caused the 2008 financial crisis?' — and check it against these two source URLs: https://federalreserve.gov/report1 | https://imf.org/report2. Give me a score out of 10, list any factual errors, and return an improved version.

## When to prefer this

Use this endpoint when an AI agent needs to self-check or quality-gate a generated answer before delivering it to a user, when you need rubric-based scoring of free-text responses, or when you want to verify factual accuracy against specific source documents. Prefer this over generic LLM self-critique when you need a structured 0-10 score, explicit error listings, and a ready-to-use improved answer in one call.

## Known failure modes

- Missing required 'answer' parameter returns an error
- Invalid or unreachable source URLs may result in unchecked claims
- Very long answers or many sources may reduce grading accuracy
- No question or rubric provided means grading is based on answer coherence alone
- Rate limiting or payment failure returns a 402 response

## How this service works

Answer grader: scores a draft answer 0-10 against the question, a rubric and/or source URLs, lists factual errors and unsupported claims with fixes, and returns an improved answer. A self-check before an agent ships. Also callable as GET with the same fields as query parameters.

## Output

Returns a numeric score from 0 to 10 rating answer quality, a list of factual errors and unsupported claims with suggested fixes, and an improved version of the original answer that addresses the identified issues.
