How this service works
Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.
Output
Returns a JSON object containing the wallet address, token contract address, network, token decimals, the raw integer balance (balance_raw), a decimal-formatted string (balance_str), and a numeric balance value — all sourced directly from an on-chain eth_call with no third-party indexer.
Example use cases
Verify DeFi wallet token holdings
“Can you check how many USDC tokens wallet 0xAbCd...1234 is holding on the Base network right now?”
Confirm airdrop receipt on Ethereum
“I need to verify whether wallet 0x9F3a...beef actually received the airdropped tokens — can you look up its balance for token contract 0x8335...2913 on Ethereum?”
Portfolio balance snapshot
“Pull the current balance of token 0x4200...0006 for my wallet 0x7777...aaaa on Base so I can track my holdings.”
Technical details
Endpoint
GEThttps://scanpay-edge.alextaghiashvili.workers.dev/api/v1/token-balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-API-key ERC-20 balance lookup on Base or Ethereum via direct eth_call. Prefer it over indexer-based solutions when you want trustless on-chain data without third-party rate limits. Use the batch sibling endpoint when checking multiple wallet/token pairs at once.
Side effects
- Invalid or malformed wallet address returns an error
- Invalid token contract address (not a valid ERC-20) may return zero or error
- Unsupported network (not Base or Ethereum) returns an error
- RPC node downtime causes timeout or 5xx response
- Missing required query parameters returns a 4xx validation error
