Resource Families

Four categories of live infrastructure data

Escudo — Live Intrusion Telemetry

XDP/eBPF kernel-captured attack data from 11 guardians across 3 continents. 1.1B+ packets filtered, 9.4K+ confirmed attacks by 3-witness quorum. Each event: IP, ports, TCP flags, TTL, OS fingerprint, witness node.

/amenazas/vivas /dislocations /escudo/mapa /federacion/amenazas
$0.005 – $1.81/call

ZK — Zero-Knowledge Proofs

Three backends: Plonky3 STARK (BabyBear, 64 FRI queries), Halo2 (UTXO membership, Merkle+Poseidon), Nova (recursive IVC folding). 196x verify/generate asymmetry. Real proofs on live chain state.

/zk/capas /zk/fold /zk/stark /poi
$0.066 – $1.98/call

Mercado — Pre-Block Signals

Own BSC/Polygon nodes + p2p sensors see transactions BEFORE block inclusion. Measured: -4 bps post-block vs +30 bps pre-block same instant. The edge isn't more data — it's earlier data.

/arb/live /mempool /mev/oportunidades /verdict
$0.005 – $8.25/call

Cadena — RadhikaChain State

Bitcoin Core fork with own genesis: UTXOs, anchored reserves, PoK defense karma, autonomous operator Alice. Height 117K+, 16 holders, 4M RADH supply. Atomic swap marketplace RADHA ↔ BTC (HTLC).

/chain/health /btc/vigilante /swap/atomico /treasury/btc
$0.033 – $49.50/call

client = x402.Client(wallet_private_key)
# Auto-handles 402 → sign → retry
data = client.get("https://x402.radhikachain.xyz/zk/capas")

JavaScript (@coinbase/x402)

import { x402Fetch } from "@coinbase/x402";
const data = await x402Fetch(
  "https://x402.radhikachain.xyz/zk/capas",
  { wallet: privateKey }
);

curl (Manual)

# 1. Get invoice
curl -i https://x402.radhikachain.xyz/zk/capas
# Returns 402 with PAYMENT-REQUIRED header

# 2. Sign with wallet (EIP-3009)
