## 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 agentdata-api-base-network-activity-endpoint-a60fa979
```

Example prompt: Pull the latest on-chain activity data from the Base network — I want to see recent transactions and events happening on Base mainnet right now.

## When to prefer this

Choose this endpoint when an AI agent needs real-time or recent on-chain activity data specifically for the Base network without API key registration. Ideal for agents with USDC wallets on Base Mainnet that need frictionless, pay-per-use access to blockchain data via the x402 micropayment protocol, especially in Claude Desktop, ElizaOS, or MCP client environments.

## Known failure modes

- Insufficient USDC balance for micropayment — 402 Payment Required returned
- Invalid or missing x402 payment header — request rejected
- Base network node unavailability causing data fetch failure
- Malformed POST body parameters — 400 Bad Request
- Rate limiting or quota exceeded on the underlying data provider

## How this service works

Pay-per-request crypto market data API for AI agents. 16 endpoints on Base Mainnet via x402 protocol. No accounts, no API keys. USDC micropayments from $0.001. Works with Claude Desktop, ElizaOS, and any MCP client.

## Output

Returns on-chain activity data for the Base blockchain network, including recent transactions, events, and network metrics as JSON, paid via $0.002 USDC micropayment per call using the x402 protocol.
