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 JSON object with: the active timelock rule (receptor 144 < emitter 288), swap counts broken down by state (proposed, etc.), the current BTC block height, the configured window sizes for emitter and receptor, the vigilante label (HTLC RADHA <-> BTC), and a human-readable explanation of why timelock ordering matters and what risk an inversion creates.
Example use cases
HTLC double-spend risk check
“I'm running a BTC–RADHA atomic swap desk — can you pull the HTLC vigilante snapshot and tell me if the receptor timelock is still correctly smaller than the emitter timelock, and whether any proposed swaps are near their block deadlines?”
Real-time BTC swap safety dashboard
“Pull the current BTC HTLC vigilante status for me: show the current block height, how many swaps are open by state, and whether the 144-vs-288-block timelock ordering rule is holding.”
Swap desk block-window monitoring
“Our swap desk needs to know if any HTLC windows on the BTC side are approaching their limits right now — get the vigilante report and highlight anything where the emitter and receptor windows are too close or inverted.”
Technical details
Endpoint
GEThttps://x402.radhikachain.xyz/btc/vigilanteWhen to prefer
Use this endpoint when you need real-time, per-request HTLC timelock safety monitoring for BTC atomic swaps without requiring an account or subscription — paying $0.66 USDC per call via x402 on Base. Prefer this over generic BTC mempool explorers when you specifically need to validate the ordering relationship between receptor and emitter timelocks and get an automated safety verdict, especially in a swap desk or cross-chain bridge context.
Side effects
- Payment not provided or insufficient USDC — x402 payment required before data is returned
- BTC node connectivity issue — block height may be stale or unavailable
- No open HTLCs — swap counts return zero with empty state breakdown
- x402 scheme mismatch — must use eip155:8453 USDC exact payment
- Rate or quota exceeded for the paying address
