How this service works
Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.
Output
A JSON object containing the token's symbol, decimals, contract address, whether it is a proxy contract (is_proxy boolean), DEX liquidity in USD, and a 'not_checked' array listing any checks (e.g. honeypot simulation, holder concentration) that could not be performed.
Example use cases
Vetting an unknown Base token before trading
“I just found a new token on Base at 0xAbC123... — can you pull its metadata, check if it's a proxy contract, and tell me how much liquidity it has on DEXs before I put any money in?”
Auditing a DeFi protocol's token contract
“We're listing a new ERC-20 token on our platform — can you check contract address 0x4200000000000000000000000000000000000006 on Base (chain 8453) and confirm whether it's a proxy and what its decimals and symbol are?”
Automated token screening in a trading bot
“Before my bot places a trade, check 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base chain 8453 and return the DEX liquidity and whether it's a proxy contract so we can decide if it's safe to trade.”
Technical details
Endpoint
POSThttps://xhagents.xyz/api/token-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, combined ERC-20 token profile — metadata, proxy status, and DEX liquidity — specifically for tokens on the Base network, and want explicit transparency about which checks were skipped. Prefer it over generic block explorers when you need machine-readable output with proxy detection and liquidity in a single call.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Token not found on any DEX results in null or zero liquidity
- Unsupported chain_id returns an error
- Proxy detection may be inconclusive for complex multi-layer proxies, noted in not_checked
- Rate limiting or payment failure (402) blocks the request
