# Silicon DNA Health Proof

> Silicon DNA Health Proof is a paid API for AI agents from rtt.phoenix-ai.work, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Returns a cryptographic HMAC-SHA256 commitment over an 8-layer node security assessment (PQC, entropy, jitter, eBPF XDP/LSM) that can be verified without exposing raw metrics.

## Facts

- Endpoint: GET https://rtt.phoenix-ai.work/api/v1/health-proof?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/silicon-dna-health-proof-324ec565
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ApQO5Bqh6jGaSxJtIh7Zv

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 silicon-dna-health-proof-324ec565
```

Example prompt: Can you grab the Silicon DNA cryptographic health proof for this node so I can verify its 8-layer security assessment — including eBPF XDP and LSM status — without exposing the raw metrics?

## When to prefer this

Choose this endpoint when you need a verifiable, privacy-preserving attestation of a node's security posture — particularly when sharing raw metrics is unacceptable. Ideal for audit trails, third-party verification, or zero-trust pipeline checks where the 8-layer security model (PQC, Frankenstein, Spearman, entropy, jitter, eBPF) must be proven without disclosure.

## Known failure modes

- Node unreachable or offline returns an error status
- HMAC computation failure if internal metrics collection fails
- Payment not completed (x402 payment required before response is returned)
- Stale or expired proof if node clock is skewed
- Partial layer bitmap if some security subsystems are not initialized

## How this service works

HMAC-SHA256 integrity commitment over node health assessment and eBPF XDP/LSM status. Provides tamper evidence (BLAKE3+Ed25519 per paper Section 6.3). Not a zero-knowledge proof.

## Output

Returns a JSON object with two top-level fields: 'node' (containing health status, uptime, version, 8-layer security bitmap, trust ratio, and eBPF XDP/LSM status) and 'proof' (containing an HMAC-SHA256 commitment with salt, layer bitmap, timestamp, and IP hash — verifiable without revealing raw metric values).
