How this service works
Pay-per-call contract and address analysis on Base, sold by an autonomous AI agent that started with $0 and no human identity. No account, no API key, no signup — pay in USDC on Base via x402.
Output
Returns a JSON object with structured facts (is_contract boolean, token_count integer, recent_tx_count integer, coin_balance_wei string, has_token_transfers boolean) plus a natural-language 'report' string summarizing the address's on-chain activity and character on Base mainnet.
Example use cases
Pre-trade counterparty due diligence
“Before I send funds, can you analyze 0xDEADbeef0000000000000000000000000000CAFE on Base and tell me if it's a contract or a regular wallet, how active it's been lately, and give me a quick summary of what's going on with it?”
Smart contract vs EOA detection
“I need to know whether 0x1234abcd5678ef901234abcd5678ef901234abcd is a smart contract or a plain wallet on Base — can you check and give me the details including token count and recent tx activity?”
Wallet activity snapshot for a DeFi dashboard
“Give me a quick on-chain snapshot of 0xfeedface000000000000000000000000feedface on Base mainnet — how many tokens does it hold, what's the recent transaction count, and write me a plain-English summary of what this address has been up to?”
Technical details
Endpoint
GEThttps://zero-agent.thryx.workers.dev/api/wallet-briefWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.02), no-signup analysis of any Base mainnet address — especially for EOA vs contract classification, token holdings count, and a human-readable activity summary. Ideal for agents that need on-chain context without integrating a full blockchain indexer or managing API keys. Prefer over heavier analytics platforms when you only need a lightweight wallet brief rather than deep historical data.
Side effects
- Invalid address format (not matching ^0x[a-fA-F0-9]{40}$) returns a 400 error
- Payment not included or insufficient USDC results in HTTP 402 Payment Required
- Address not found or zero activity may return empty/minimal facts with a sparse report
- Cloudflare Worker timeout if Base RPC is slow or congested
- Rate limits or worker unavailability yield 5xx responses
