# OathScore
> Every API makes promises. OathScore checks the receipts.
**The trust layer for AI agents.** Two products:
1. **`/now`** — A single endpoint returning the current state of the world for trading agents. Exchange status, volatility, events, regime, data health — one call.
2. **OathScore Ratings** — Independent, continuous verification of data API accuracy, uptime, freshness, and reliability. The credit bureau for data APIs.
## For AI Agents
```bash
# What's happening right now?
curl https://api.oathscore.dev/now
# Should I trust this data source?
curl https://api.oathscore.dev/score/curistat
# Compare two sources
curl https://api.oathscore.dev/compare?apis=curistat,alphavantage
```
## For MCP-Compatible Agents (Claude Code, Cursor, etc.)
```json
{
"mcpServers": {
"oathscore": {
"command": "python",
"args": ["-m", "oathscore_mcp"]
}
}
}
```
Requires: `pip install httpx mcp[cli]` and clone this repo.

## Architecture
```
[Monitoring Service - Railway $5/mo]
Every 60s: ping all rated APIs (uptime, latency)
Every 5m: check data freshness
Every 1h: record forecast snapshots
Every 24h: compare forecasts to actuals (accuracy)
Store: Supabase (free tier)
[/now Endpoint - Cloudflare Workers $0/mo]
Every 60s: fetch VIX, compute exchange status, read events
Serve: cached JSON, max-age=30, ETag support
[Scoring Engine - Cloudflare Workers $0/mo]

Serve: /score, /compare, /alerts endpoints
```
## Integration Examples
### CrewAI
```python
from crewai import Agent, Task
from crewai_tools import MCPTool
# Connect to OathScore MCP
oathscore = MCPTool(server_command="python -m oathscore_mcp")
analyst = Agent(
role="Market Analyst",
tools=[oathscore],
goal="Assess current market conditions before trading"
)
task = Task(
description="Check if markets are open and get current volatility regime",
agent=analyst
)
```
### LangChain
```python
from langchain_mcp import MCPToolkit
toolkit = MCPToolkit(server_command="python -m oathscore_mcp")
tools = toolkit.get_tools()
# Use in any LangChain agent
from langchain.agents import initialize_agent
agent = initialize_agent(tools, llm, agent="zero-shot-react-description")
agent.run("What's the current VIX level and are US markets open?")
```
### Direct HTTP (any language)
```python
import httpx
# World state in one call
now = httpx.get("https://api.oathscore.dev/now").json()
print(f"VIX: {now['volatility']['vix']}")
print(f"CME: {'OPEN' if now['exchanges']['CME']['is_open'] else 'CLOSED'}")
print(f"Next event: {now['events']['next_event']}")
# API quality check before committing to a data source
score = httpx.get("https://api.oathscore.dev/score/polygon").json()
if score.get("composite_score", 0) < 70:
print("Warning: data source quality below threshold")
```
### Claude Desktop / Claude Code
Add to your MCP config (`~/.claude/mcp.json` or Claude Desktop settings):
```json
{
"mcpServers": {
"oathscore": {
"command": "python",
"args": ["-m", "oathscore_mcp"]
}
}
}
```
Then ask Claude: *"What's the current market state?"* or *"How reliable is Alpha Vantage?"*
