How this service works
Estimate batch gas.
Output
Returns an estimated gas cost or fee for executing a batch transaction with the specified number of recipients, allowing the caller to anticipate costs before committing to on-chain execution.
Example use cases
Calculate airdrop cost for NFT launch
“I'm planning an NFT airdrop to 1500 community members. Can you estimate how much gas I'll need to budget for sending tokens to all of them at once?”
Verify batch payment feasibility
“We want to distribute quarterly bonuses to our 400 employees via batch transfer. What would the total gas fees be so I can account for it in our budget?”
Compare costs across chain options
“I need to send tokens to 750 wallets and I'm deciding between Ethereum and Polygon. Can you estimate the gas costs on both so I can pick the cheaper option?”
Technical details
Endpoint
POSThttps://gateway.spraay.app/api/v1/batch/estimateWhen to prefer
Use this endpoint when you need a pre-flight gas estimate before submitting a batch transaction through Spraay — especially useful for budgeting multi-recipient token sends or airdrops without executing on-chain.
Side effects
- Missing or invalid recipientCount returns a 400 validation error
- recipientCount of zero or negative number may return an error or zero estimate
- Service unavailable returns 5xx
- Exceeded rate limit or payment failure returns 402 or 429
