# RadhikaChain Atomic Swap Status Feed

> RadhikaChain Atomic Swap Status Feed is a paid API for AI agents from x402.radhikachain.xyz, paid per call via x402, $12.896/call, status unknown (last checked 2026-09-13).

Returns the current status of atomic swap activity between RADH and BTC, including open HTLC counts and how-it-works metadata for the custodian-free cross-chain swap desk

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-atomic-swap-status-feed-8e29e5b3
```

Example prompt: Pull the latest atomic swap status from RadhikaChain — I want to see how many RADH-BTC swaps are open right now and whether any HTLC are live on the desk.

## When to prefer this

Use this endpoint when you need a real-time, custodian-free atomic swap status snapshot specifically for the RADH-BTC pair on RadhikaChain, paid per-call in USDC with no account or subscription required. Prefer this over centralized exchange APIs when you need trustless, on-chain verifiable swap state with HTLC transparency.

## Known failure modes

- Empty swaps array with total=0 when no swaps are active (not an error, just no data)
- HTTP 402 Payment Required if USDC x402 payment header is missing or malformed
- Payment rejected if USDC amount does not exactly match $2.48 on Base (eip155:8453)
- Service unavailable if RadhikaChain node is offline or unreachable
- Stale data if the desk snapshot has not been recently refreshed

## 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 JSON object containing an array of current swaps (may be empty), total swap count, count of open swaps, the product label ('Atomic Swap RADH <-> BTC'), a boolean confirming non-custodial operation, and a plain-language explanation of the SHA-256 HTLC mechanism used to lock funds on both chains.
