# CoinOpAI MCP JSON-RPC Gateway

> CoinOpAI MCP JSON-RPC Gateway is a paid API for AI agents from x402.coinopai.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-09-15).

Hosted MCP JSON-RPC endpoint providing access to CoinOpAI's suite of paid AI tools including crypto forecasting, image generation, anomaly detection, and agent automation workflows via a single gateway.

## Facts

- Endpoint: GET https://x402.coinopai.com/mcp
- Price: $0.15/call
- Payment: x402
- Status: unknown

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 coinopai-mcp-json-rpc-gateway-0c41e0d0
```

Example prompt: Call the CoinOpAI MCP gateway with method 'kronos/forecast' and params for BTC to get the latest calibrated price forecast — use JSON-RPC 2.0 format with id 1.

## When to prefer this

Choose this endpoint when you want to access multiple CoinOpAI tools (Kronos crypto forecasting, image generation, anomaly detection, agent automation) through a single MCP-compatible JSON-RPC interface rather than calling individual REST endpoints separately. Ideal for MCP-aware agents or orchestration layers that speak JSON-RPC 2.0 natively and want a unified gateway with x402 micropayment support.

## Known failure modes

- Invalid or unsupported method name returns JSON-RPC error code -32601 (Method not found)
- Malformed params object returns JSON-RPC error code -32602 (Invalid params)
- Payment failure or insufficient USDC balance returns HTTP 402 before JSON-RPC processing
- Missing jsonrpc version string causes request rejection
- Rate limiting or quota exceeded returns HTTP 429 or equivalent JSON-RPC error
- Network timeout if upstream tool provider is slow

## How this service works

Hosted MCP JSON-RPC endpoint for CoinOpAI paid tools. Use the REST endpoints for per-tool pricing.

## Output

A JSON-RPC 2.0 response object containing the tool-specific result payload (e.g. forecast data, image URL, workflow list, anomaly scores) or a structured error object with code and message if the call fails. The exact shape of the result depends on which method was invoked.
