# RadhikaChain Trace Requests — Chain Telemetry

> RadhikaChain Trace Requests — Chain Telemetry is a paid API for AI agents from x402.radhikatmosphere.com, paid per call via x402, $0.858/call, status unknown (last checked 2026-09-15).

Returns traced blockchain request records including chain telemetry and defense intelligence data, pay-per-call via x402 USDC on Base.

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-trace-requests-chain-telemetry-d40153a7
```

Example prompt: Pull the latest request traces from RadhikaChain so I can see what on-chain requests have been recorded and check for any anomalies in the telemetry.

## When to prefer this

Choose this endpoint when you need raw on-chain request trace data from the RadhikaChain sensor network on Base, particularly for security/defense intelligence workflows or to verify zero-knowledge computation jobs (Halo2, Nova, Plonky3). Prefer it over general blockchain explorers when you need pay-as-you-go telemetry without account setup and specifically want RadhikaChain's devp2p-level request tracing rather than standard block/transaction data.

## Known failure modes

- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Insufficient USDC balance on Base for the $0.165 per-call fee
- Network timeout if the telemetry backend is unavailable
- Empty traces array returned when no requests have been recorded in the current window
- Malformed response if the trace store is being reset or reindexed

## 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 containing a 'traces' array with recorded blockchain request trace entries. When no traces are available the array is empty. Each entry is expected to contain telemetry details about on-chain requests processed by the RadhikaChain sensor network.
