How this service works
한국 HS854232 무역 통계, 코스닥 OpenDART 7일 공시 목록과 Base ERC-20 계약 기초 사실의 무료 목록·샘플 및 x402 고정 버전 JSON API.
Output
A JSON object containing basic on-chain facts about the specified ERC-20 token contract deployed on the Base network, likely including token name, symbol, decimals, total supply, and contract address details.
Example use cases
Identify unknown Base token contract
“I found a token at Base address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — can you look up what token it is and give me its basic on-chain details like name, symbol, and decimals?”
DeFi portfolio contract verification
“Before I interact with this Base contract, can you fetch the basic ERC-20 facts for 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 so I can confirm it's the right token?”
Token metadata enrichment for analytics
“I need the on-chain metadata for the ERC-20 contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — name, symbol, decimals, whatever basic facts are available.”
Technical details
Endpoint
GEThttps://kmde-snapshot-candidate.onrender.com/v1/base/token/0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913.json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, inexpensive ($0.005 USDC) on-chain facts for a specific ERC-20 contract on the Base network and already know the contract address. It is suitable for single-address lookups rather than bulk queries. Prefer this over general blockchain explorers when you need a simple, programmatic JSON API response for agent consumption without scraping.
Side effects
- Invalid or malformed contract address (not matching ^0x[0-9a-fA-F]{40}$) returns an error
- Address is valid Ethereum format but not an ERC-20 contract on Base — may return empty or error response
- Payment of $0.005 USDC not completed via x402 protocol results in 402 Payment Required
- Network or hosting service unavailability on Render.com causes timeout or 503 error
- Contract address exists but has minimal on-chain data resulting in sparse response
