# rootAI MCP Pro – Recent Signals

> rootAI MCP Pro – Recent Signals is a paid API for AI agents from mcp.rootedge.ai, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns the latest graded market intelligence signals (e.g. liquidity zones, directional bias) for crypto assets, gated by x402 micropayment.

## Facts

- Endpoint: POST https://mcp.rootedge.ai/pro
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 rootai-mcp-pro-recent-signals-dc8fb106 -d '<json body>'
```

Example prompt: Pull the 20 most recent rootAI market signals with a minimum grade of B — I want to see which coins have liquidity zone or directional signals right now.

## When to prefer this

Use this endpoint when you need freshly graded, real-time crypto market intelligence signals (liquidity zones, directional bias) from rootAI and are willing to pay $0.01 USDC per call via x402. Prefer this over free-tier endpoints when you need higher signal quality or volume, and over generic market data APIs when you specifically want pre-scored, graded trade signals rather than raw price data.

## Known failure modes

- Payment not authorized or insufficient USDC balance — x402 payment required before data is returned
- Invalid min_grade value outside A/B/C/D enum — request rejected with validation error
- limit out of range (must be 1–100) — request rejected
- Endpoint unavailable or rate-limited — server error response
- Missing required params.name or params.arguments fields — JSON-RPC error

## How this service works

rootAI MCP Free and Pro endpoints for market intelligence, live tools, and x402-paid signals.

## Output

A JSON array of recent market signals, each with a coin ticker (e.g. BTC), signal kind (e.g. LIQ_ZONE_NEAR), letter grade (A–D), numeric score, and direction (long/short). The call costs $0.01 USDC via x402 micropayment and returns up to 100 signals depending on the limit parameter.
