How this service works
EVM Wallet Balances (polygon). Polygon ERC-20 token balance and native POL balance for any wallet: up to 20 ERC-20 tokens (?tokens=) in one call, with symbols, decimals and human-readable amounts. Live chain head.
Output
Returns the native MATIC balance for the specified Polygon wallet address, expressed as an on-chain value (typically in wei or formatted MATIC units), reflecting the current state of the blockchain at query time.
Example use cases
DeFi bot gas check
“Before submitting the transaction, check if wallet 0xAbCd1234567890EF1234567890abcdef12345678 has enough MATIC on Polygon to cover gas fees.”
Portfolio balance tracker
“Pull the current MATIC balance on Polygon for my wallet 0x1234567890abcdef1234567890ABCDEF12345678 so I can update my portfolio dashboard.”
Airdrop eligibility verification
“I need to verify that wallet 0xDeAdBeEf0000000000000000000000000000cafe actually holds some MATIC on Polygon before I whitelist it for the airdrop.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/polygon/balance/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the native MATIC balance on the Polygon network for an EVM-compatible wallet address. Prefer this over Ethereum or BSC balance endpoints when the user's assets are on Polygon. It is ideal for DeFi agents, portfolio trackers, gas-check automations, and airdrop verification workflows that require Polygon on-chain data.
Side effects
- Invalid or malformed wallet address returns an error
- Address with zero balance may return 0 rather than an error
- Network congestion or RPC issues may cause timeouts
- Non-Polygon (wrong network) address format may cause unexpected results
- Rate limiting or payment failure may block the request
