# Node-1000 Immutable Beacon MCP

> Node-1000 Immutable Beacon 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).

Processes data through an immutable beacon node endpoint, providing tamper-resistant computation or anchoring via a fixed, persistent node identifier.

## Facts

- Endpoint: POST https://api.m2mcent.com/node-1000-immutable-beacon-mcp/api/process?utm_source=zero.xyz
- Price: $1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/node-1000-immutable-beacon-mcp-6a371c02
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_MKgG1sGGm3SlHAcIOHd3b

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 node-1000-immutable-beacon-mcp-6a371c02 -d '<json body>'
```

Example prompt: Process this data payload through the immutable beacon node and give me back the result: 'transaction-hash-abc123-payload-data'.

## When to prefer this

Choose this endpoint when you need to process data through a fixed, immutable beacon node with a persistent identifier (node-1000), particularly for use cases requiring tamper-resistance, auditability, or anchoring of data to a stable, non-rotating node. Prefer this over generic compute endpoints when the immutability and beacon properties of the node are important to your workflow.

## Known failure modes

- Malformed or empty data string returns a 400-level error
- Payment failure (insufficient USDC or x402 protocol error) prevents processing
- Node unavailability may return a 503 or timeout
- Oversized payload may be rejected if data string exceeds undocumented limits
- Non-string data types submitted to the data field may cause parsing errors

## 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 processed response from the immutable beacon node, likely including a confirmation, attestation, or computation result tied to the submitted data string. The exact response format is not publicly documented but is expected to be a JSON object with node-specific output fields.

## Response schema (JSON Schema)
