# RadhikaChain ZK Circuit Capabilities Map

> RadhikaChain ZK Circuit Capabilities Map is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $0.066/call, status unknown (last checked 2026-10-11).

Returns a structured map of the three live zero-knowledge proof circuits (Halo2+Poseidon, Nova IVC, Plonky3 STARK) and which circuit answers which type of claim

## Facts

- Endpoint: GET https://x402.radhikachain.xyz/zk/capas?utm_source=zero.xyz
- Price: $0.066/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/radhikachain-zk-circuit-capabilities-map-70f10486
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_vHxkzuvrwf8bOiZ_f8Bpw

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-circuit-capabilities-map-70f10486
```

Example prompt: Show me the map of all live ZK circuits on RadhikaChain — I need to know which one handles membership proofs versus swap folds versus batch sums.

## When to prefer this

Use this endpoint when you need to determine which ZK circuit on RadhikaChain is appropriate for a given proof type before submitting a proof or claim. It is the canonical registry of circuit-to-claim routing and should be consulted before interacting with any ZK proof submission endpoint on RadhikaChain.

## Known failure modes

- Service unavailable if RadhikaChain node is down (5xx)
- Empty or partial response if circuit registry is not yet initialized
- Payment failure if USDC balance is insufficient for the $0.066 per-call fee
- Rate limiting if called too frequently

## 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

A structured map of the three live ZK circuit layers on RadhikaChain: Halo2+Poseidon (membership proofs), Nova IVC (swap fold proofs), and Plonky3 STARK (batch sum proofs), including which circuit is authoritative for which type of claim.
