How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object containing total_wei (the summed value of all input Wei amounts as a string), transaction_count (integer count of inputs), a status field ('pass'), the operation name, and an evidence block confirming no data was retained, the SHA-256 hash of the input, and zero external calls made.
Example use cases
Pre-flight EVM batch cost check
“Before I submit this batch of EVM transactions, can you add up all the Wei values — ["500000000000000000", "250000000000000000", "750000000000000000"] — and tell me the total and how many transactions are in the batch?”
Reconcile multi-sender ETH transfers
“I have a list of individual ETH transfer amounts in Wei from different senders: ["1000000000000000", "2000000000000000", "3000000000000000", "500000000000000"]. Can you sum them all up and confirm the transaction count?”
Agent wallet treasury audit
“I need to verify the cumulative Wei value of these pending outbound transactions before my agent executes them: ["10000000000000000", "20000000000000000"]. What's the grand total in Wei and how many transactions is that?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-batch-value-sum?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, verifiable, in-memory sum of multiple EVM Wei values without any data leaving the service or being stored — ideal for pre-flight transaction validation, batch cost estimation, or audit trails where the SHA-256 evidence hash matters. Prefer it over client-side summation when you need a trustless, third-party-verifiable computation result with no external calls.
Side effects
- Array exceeds 256 items — request rejected
- Individual string value exceeds 8192 characters — validation error
- Non-numeric string in values_wei array — computation error
- Empty array input — returns total_wei of 0 and transaction_count of 0
- Malformed JSON body — 400 bad request
- Payment not included or insufficient USDC — 402 payment required
