# RadhikaChain ZK-Attested Resonance Score

> RadhikaChain ZK-Attested Resonance Score is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $0.099/call, status unknown (last checked 2026-10-11).

Returns a zero-knowledge attested cross-node resonance score with a cryptographic commitment proving that reporting nodes ran the canonical shield binary with XDP attached at the queried block height.

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 radhikachain-zk-attested-resonance-score-5bf307e2
```

Example prompt: Fetch the zero-knowledge attested resonance score from RadhikaChain — I need the cross-node score plus the cryptographic commitment proving that reporting nodes were running the canonical shield binary with XDP attached.

## When to prefer this

Choose this endpoint when you need not just the raw cross-node resonance score but cryptographic proof that the nodes generating it were running the correct canonical XDP shield binary — i.e. when auditability and trustlessness matter. Prefer it over the non-ZK resonance endpoint whenever the consumer needs to independently verify node compliance without trusting the reporting node directly.

## Known failure modes

- No quorum of reporting nodes available — returns error or empty attestation
- Block height unavailable or pruned — commitment cannot be generated for that height
- ZK proof generation failure — attestation missing or malformed response
- Payment not accepted — x402 payment required, 402 response if unpaid
- Canonical binary hash mismatch — nodes running non-canonical binary excluded from score

## How this service works

Telemetria de cadena, inteligencia de defensa y computo verificable (Halo2, Nova, Plonky3). Pago por peticion en USDC nativo en Base (eip155:8453) mediante x402 v2 scheme exact; sin cuenta ni suscripcion. Catalogo canonico: GET /.well-known/x402.

## Output

Returns a cross-node resonance score (numeric agreement measure across reporting nodes) paired with a zero-knowledge commitment that cryptographically attests each reporting node was executing the canonical shield binary with XDP kernel-level filtering attached at the queried block height. The commitment enables trustless verification without revealing node-level internals.
