# Newsignal — full agent index

> Verified impersonal indicator forecasts for AI agents and trading systems that need scored context, not tip-channel calls.

## Bases

| Surface | URL |
|---------|-----|
| Web | https://new-signal-web.vercel.app |
| REST API | https://new-signal-api.vercel.app |
| OpenAPI | https://new-signal-api.vercel.app/openapi.json |
| MCP install | https://new-signal-web.vercel.app/mcp-install.json |
| Hosted MCP | `mcpUrl` field in mcp-install.json (null until published) |

## Product truth

- Marketplace of **feeds** that publish sealed forecasts into an append-only SHA-256 commit log.
- Lifecycle: sealed → revealed → resolved → feedback.
- A feed is **Listed** only after its version clears the sample and scoring gates.
- Not investment advice. No trade execution.

## Rules

Impersonal indicators only. Never invent skill. Always surface `disclaimer`. Verify hashes after reveal.
