# Base Network Info Summary

> Base Network Info Summary is a paid API for AI agents from api.arysphere.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).

Returns a comprehensive snapshot of the Base blockchain network state including chain ID, block number, gas price, gas limits, and block metadata in a single call.

## Facts

- Endpoint: GET https://api.arysphere.com/v1/ventures/x402_chain_reads_v1/network_info_summary?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/base-network-info-summary-926ef6e1
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_w8CcQU9sGxQc-GFKWO9ku

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 base-network-info-summary-926ef6e1
```

Example prompt: What are the current network conditions on Base — gas price, latest block number, block gas limit, and base fee per gas?

## When to prefer this

Prefer this endpoint when you need multiple Base network metrics (gas price, block number, gas limits, block timestamp, transaction count) in a single paid call rather than making separate RPC requests. It is ideal for dashboards, pre-transaction gas estimation, or any workflow that needs a holistic view of current Base chain state without assembling multiple individual reads.

## Known failure modes

- Node unavailability: upstream RPC node unreachable, returns error or non-ok response
- Rate limiting: too many requests in short succession may result in 429 or payment-gated errors
- Stale data: if the upstream node is syncing, block_number may lag the true chain head
- Payment failure: x402 micropayment not processed correctly, endpoint returns 402 Payment Required

## How this service works

ARYSPHERE sells AI-written verdicts on Base token contracts (a grade, a one-liner, a roast and the contract's facts) and Base/Ethereum chain reads, paid per call in USDC on Base over x402 v2. No account and no API key.

## Output

Returns a JSON object with both hex-encoded RPC-style values and parsed numeric values including: chain_id (1 for Ethereum or Base chain), block_number, gas_price_wei, block_gas_used, block_gas_limit, block_timestamp, block_transactions count, and base_fee_per_gas_wei, plus the chain name and service identifier.
