# ExactGate x402 Validator – Base Network Health

> ExactGate x402 Validator – Base Network Health is a paid API for AI agents from exactgate-x402.insertnameheree.chatgpt.site, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns real-time Base (chain ID 8453) network health metrics including block number, gas price, and RPC latency, paid per call via x402 USDC micropayment.

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 exactgate-x402-validator-base-network-health-251502c0
```

Example prompt: Can you check if the Base network is healthy right now — I need the current block number, gas price, and RPC latency before I submit a transaction?

## When to prefer this

Use this endpoint when you need a deterministic, pay-per-call snapshot of Base network conditions (gas price, block number, RPC latency) before submitting a transaction or deploying a contract. Prefer it over free public RPC calls when you need a reliable, metered SLA and audit trail via x402 micropayment receipts. Best suited for automated agent workflows that need lightweight preflight checks on Base L2 without maintaining a full node connection.

## Known failure modes

- Payment not included or malformed x402 header returns 402 Payment Required
- Base RPC node temporarily unreachable returns degraded or error response
- Network spike may cause stale or delayed block number
- Invalid request format returns 400 Bad Request
- Service unavailability returns 503 with no health data

## How this service works

Deterministic Base receipt and transaction preflight APIs, paid per call with x402 USDC.

## Output

A JSON object containing: chainId (8453 for Base mainnet), blockNumber (latest finalized block), gasPriceWei (current gas price as a string in wei), and rpcLatencyMs (round-trip RPC response time in milliseconds). Useful for preflight validation before on-chain transactions.
