How this service works
EVM Batch Gas Sum: EVM Batch Gas Sum sums gas limits and fee ceilings across a transaction batch from bounded caller-supplied values without an external provider. Call EVM Batch Gas Sum before signing, submitting, replacing, or accepting an EVM/Base transaction assembled from caller-owned data. Returns normalized transaction evidence, calculated budget or shape findings, and a fail-closed preflight status for EVM Batch Gas Sum as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base…
Output
Returns a JSON object with total_gas (integer sum of gas across all transactions), fee_ceiling_wei (string, maximum fee in wei), and transaction_count (integer). Also includes an evidence block confirming no data retention, the input SHA-256 hash, and zero external calls made during processing.
Example use cases
Pre-submit budget check for DeFi batch
“I'm about to send a batch of 8 DeFi swaps on Ethereum — can you preflight them to get the total gas and fee ceiling in wei before I broadcast anything?”
Gas budget validation for NFT mint batch
“I have 15 NFT mint transactions ready to go — run them through the batch gas sum so I can confirm the total gas fits within my budget before executing.”
Agent cost estimation before multi-transfer
“My agent needs to send tokens to 20 addresses in one batch — can you calculate the combined gas total and fee ceiling for all those transfer transactions first?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-batch-gas-sumWhen to prefer
Use this endpoint when an agent needs to preflight a batch of EVM transactions before submission to estimate total gas spend and fee ceiling in a single call. Prefer it over individual per-transaction gas estimates when you have multiple transactions and need an aggregated budget figure. Ideal for agent workflows that must validate gas budget before committing to on-chain execution, especially when privacy matters since no data is retained.
Side effects
- Batch exceeds 256 transaction limit — request rejected
- Individual transaction object exceeds 128 properties — validation error
- Malformed transaction objects — parsing failure or unexpected results
- Missing or empty transactions array — error response
- Network timeout on large batches approaching the 256-item limit
