# Interstellar Node Registry MCP

> Interstellar Node Registry MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1/call, status unknown (last checked 2026-10-12).

Registers, looks up, or manages nodes in an interstellar (distributed/multi-node) registry via a machine-to-machine agentic endpoint.

## Facts

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 interstellar-node-registry-mcp-ab99e973 -d '<json body>'
```

Example prompt: Register my node with the interstellar node registry using the identifier 'node-alpha-7' and its associated metadata so I can look it up later.

## When to prefer this

Choose this endpoint when you need to register, query, or manage nodes in a distributed interstellar node registry via a paid agentic API. Best suited for infrastructure automation agents managing multi-node networks where node discovery and registration are required programmatically.

## Known failure modes

- Missing or malformed 'data' field in request body returns a validation error
- Node identifier not found in registry returns a not-found or empty result
- Payment of 1 USDC not received causes a 402 Payment Required response
- Registry service unavailable or timeout returns a 5xx error
- Duplicate registration may return a conflict or overwrite depending on registry policy

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a registry response confirming the operation on the node entry, which may include the registered node's identifier, metadata, status, and any relevant registry confirmation details.
