# x402.radhikatmosphere.com Mempool Telemetry

> x402.radhikatmosphere.com Mempool Telemetry is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Returns live Ethereum mempool telemetry data observed from a devp2p network sensor tracking pending transactions.

## Facts

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 x402-radhikatmosphere-com-mempool-telemetry-d83b75d4
```

Example prompt: Can you pull the latest mempool telemetry from that devp2p sensor — I want to see what pending Ethereum transactions look like right now and how congested the mempool is?

## When to prefer this

Choose this endpoint when you need real-time, raw mempool telemetry sourced directly from a devp2p peer node rather than aggregated or delayed data from block explorers. It is well-suited for latency-sensitive applications like gas fee optimization bots, MEV monitoring, or DeFi transaction timing where observing live pending transactions before block inclusion is critical.

## Known failure modes

- Sensor connectivity issues causing stale or unavailable data
- Network peer disconnection resulting in incomplete mempool view
- Rate limiting or payment verification failure for the $0.005 USDC per-call fee
- Empty mempool snapshot during low-network-activity periods
- Timeout if devp2p node is syncing or catching up

## 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 live mempool telemetry data collected by a devp2p peer-to-peer network sensor, including information about pending (unconfirmed) Ethereum transactions such as transaction counts, gas price distribution, and mempool depth or congestion metrics observed in real time.
