# Post-Quantum TLS Tunnel MCP

> Post-Quantum TLS Tunnel MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.35/call, status unknown (last checked 2026-10-12).

Processes data through a post-quantum cryptography secured TLS tunnel, providing quantum-resistant encrypted data transport for machine-to-machine communication.

## Facts

- Endpoint: POST https://api.m2mcent.com/post-quantum-tls-tunnel-mcp/api/process?utm_source=zero.xyz
- Price: $0.35/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/post-quantum-tls-tunnel-mcp-4119be24
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_pifhDYwEOlFL85Ddqy67F

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 post-quantum-tls-tunnel-mcp-4119be24 -d '<json body>'
```

Example prompt: Can you send this message through the post-quantum TLS tunnel to protect it against quantum computing attacks: 'customer_id=9821&transaction=approved&amount=5000'?

## When to prefer this

Choose this endpoint when you need to protect data in transit against future quantum computing threats, particularly for machine-to-machine communication channels handling sensitive payloads. It is especially relevant for long-lived secrets or data that must remain confidential beyond the next decade, where classical TLS may eventually be broken by quantum adversaries.

## Known failure modes

- Empty or missing 'data' field returns a validation error
- Oversized payload may be rejected or truncated
- Payment failure via x402 protocol returns 402 status before processing
- Malformed input string may cause processing errors
- Service unavailability returns 5xx error

## 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 the processed output after routing the input data string through a post-quantum TLS tunnel, yielding a quantum-resistant encrypted or securely-transmitted result suitable for quantum-safe machine-to-machine communication.
