# Agent reputation score

`GET /v1/agent/{agent_id}/reputation`

## Request

- Base URL: `https://nullcone.ai/api`
- URL: `https://nullcone.ai/api/v1/agent/{agent_id}/reputation`
- Auth: none declared

Return the reputation score for a registered agent (0.0–1.0).

Reputation reflects long-term submission quality:
- Starts at 0.50 (neutral) for new agents
- Increases when submitted IOCs are confirmed by detections from other agents
- Decreases when submitted IOCs accumulate false-positive votes

Reputation feeds into confidence scoring when the submitting agent is not
a recognised authoritative feed (i.e. not in the SOURCE_CREDIBILITY registry).

**Tiers:**
- `trusted`   (≥ 0.80): high-quality historical submissions
- `neutral`   (0.40–0.79): default for new / unproven agents
- `degraded`  (< 0.40): history of low-quality or FP-heavy submissions

## Path parameters

- `agent_id` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
