How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a list of ERC-20 token balances associated with the specified wallet address on the MegaETH network, including token contract addresses and their respective balance amounts. If specific contract addresses are provided, results are filtered to those tokens only.
Example use cases
DeFi portfolio snapshot for a wallet
“Can you pull up all the token balances for MegaETH wallet 0xAbC123... so I can see what ERC-20 tokens it currently holds?”
Check specific token holdings on MegaETH
“Does the wallet 0xAbC123... hold any of these tokens on MegaETH — the contracts are 0xDeFi1... and 0xDeFi2...? Tell me the balances.”
Audit wallet assets before a transfer
“Before I make a transfer, can you check the full ERC-20 token balances on MegaETH for the address 0xAbC123... and list everything it holds?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/megaeth/token/balancesWhen to prefer
Use this endpoint when you specifically need ERC-20 token balances on the MegaETH network. It supports filtering by contract address, making it efficient for targeted balance lookups rather than full wallet scans. Prefer this over generic multi-chain balance APIs when MegaETH is the target network, and it is cost-effective at $0.01 per call via x402 micropayments.
Side effects
- Invalid or malformed wallet address returns an error or empty result
- Non-existent contract addresses return zero balances or an error
- MegaETH network unavailability causes timeout or 5xx error
- Missing required 'owner' field results in a 400 bad request
- Payment failure via x402 blocks the request before execution
