How this service works
Market and on-chain data, paid per call in USDC on Base through the x402 protocol. No accounts, no API keys. Sources are public data providers; the value added here is keyless access, edge caching, multi-source fallback and normalised responses.
Output
A normalised JSON response containing the on-chain balance (amount and token/asset type) for the queried address on the specified chain, sourced from public blockchain data with multi-source fallback and edge caching.
Example use cases
DeFi portfolio balance check
“Can you look up the on-chain balance for wallet 0x1234...abcd on Base and tell me how much it holds?”
Pre-transaction funding check
“Before I send a payment, check whether wallet 0xDead...Beef has enough native balance on Base to cover the transaction.”
Airdrop eligibility verification
“I need to verify the current token balance of address 0xFeed...C0de on-chain — can you fetch that for me without me needing to set up an API key?”
Technical details
Endpoint
GEThttps://x402.santyvv.com/api/chain/balance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, on-demand on-chain balance lookups without setting up an account or API key, and you are willing to pay $0.01 USDC per call via the x402 micropayment protocol. Ideal for agents that need occasional balance checks without committing to a subscription, or when you want normalised multi-chain responses with built-in fallback.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported chain identifier results in a 400-level error
- Payment failure via x402 (insufficient USDC or wallet issue) blocks the request
- RPC/data provider outage on all fallback sources may cause a temporary unavailability
- Rate or network issues at the edge cache may introduce stale or delayed data
