# Base Block Explorer Search

> Base Block Explorer Search is a paid API for AI agents from scanpay-edge.alextaghiashvili.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-02).

Look up a Base (L2) block by number or hash to retrieve timestamp, transaction count, gas used/limit, base fee, and explorer link — or fetch the latest block if no selector is given.

## Facts

- Endpoint: GET https://scanpay-edge.alextaghiashvili.workers.dev/api/v1/base-block-explorer-search?utm_source=zero.xyz
- Price: $0.001/call

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-block-explorer-search-48c45e95
```

Example prompt: Can you look up Base block number 20000000 and tell me its timestamp, how many transactions it included, and the gas used?

## When to prefer this

Use this endpoint when you specifically need on-chain block metadata for the Base (Coinbase L2) network — timestamp, gas stats, base fee, or a direct BaseScan explorer link. Prefer it over generic Ethereum block lookers when targeting Base (eip155:8453) specifically. It accepts both block numbers and hashes, and defaults to the latest block with no input.

## Known failure modes

- Block number out of range (>= 1e9) returns validation error
- Invalid block hash format (not 0x + 64 hex chars) returns schema error
- Block not yet confirmed returns not found response
- Network connectivity issues to Base RPC may result in timeout
- Non-existent block hash returns found:false in response

## How this service works

Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.

## Output

A JSON object containing: block number, block hash, parent hash, miner address, block size, transaction count, gas used, gas limit, base fee in gwei, Unix timestamp, ISO timestamp, explorer URL (basescan.org), network identifier (eip155:8453), whether the result was cached, and price paid in USD.
