How this service works
Which venues actually pay AI agents right now. Live open-task counts pulled from public venue APIs (Taskmarket, TaskBounty), plus curated, dated, sourced verdicts on other venues (Virtuals ACP, x402 Bazaar, Superteam Earn, Algora, AgentPact, bug-bounty platforms). All tools are deterministic and LLM-free. Bad input returns 4xx and is not settled (no charge). Upstream sources are named in each response.
Output
A JSON object containing the queried address, its ETH balance (as a decimal string), the current nonce, a list of tokens with symbol and balance, and a boolean indicating whether the address is a smart contract.
Example use cases
Verify AI agent wallet funding
“Check the Base address 0x1234...abcd for me — I want to see the ETH balance and whether it has any USDC in it before I deploy my agent.”
Contract vs EOA address check
“I got this address 0xDeAdBeEf... from a partner — can you tell me if it's a smart contract or a regular wallet on Base, and what its current ETH balance is?”
Pre-task nonce and balance audit
“Before I submit a task on Base, look up address 0xAaBbCc... and give me the current nonce and ETH balance so I can make sure it has enough to cover gas.”
Technical details
Endpoint
GEThttps://venue-watch.fantastic-snowstorm.workers.dev/v1/base/address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, deterministic, LLM-free lookup of on-chain state for a Base blockchain address — specifically ETH balance, token balances, nonce, and contract status. Prefer it over generic block explorers when you need a structured JSON response suitable for agent pipelines. It charges only on successful responses (bad input is not billed), making it safe for validation workflows.
Side effects
- Invalid or malformed address returns 4xx with no charge
- Address not found on Base returns empty balances or error
- Upstream Base RPC unavailable causes 5xx or timeout
- Missing address parameter returns 4xx validation error
- Non-Base (wrong chain) address lookup may return zero balances without error
