How this service works
EVM Batch Value Sum: EVM Batch Value Sum sums bounded raw transaction values for a batch funding view from bounded caller-supplied values without an external provider. Call EVM Batch Value 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 Value Sum as versioned deterministic JSON. Price: $0.001 USDC via x40…
Output
Returns a JSON object with the summed total in wei as a string, the count of input transactions, the operation name, a pass/fail status, and an evidence block confirming no data retention and no external calls, plus the SHA-256 hash of the input for auditability.
Example use cases
Preflight batch ETH transfer check
“Before I submit this batch of ETH transfers, sum up these wei values for me — 1000000000000000000, 500000000000000000, and 250000000000000000 — so I can confirm the total outflow before signing.”
Aggregate DeFi swap values
“I have a list of 10 DeFi swap amounts in wei: 300000, 450000, 120000, 780000, 210000, 560000, 390000, 670000, 840000, 430000 — add them all up and tell me the grand total and transaction count.”
Validate batch payload total before posting
“I'm about to POST a batch of on-chain payments and need to verify the total wei commitment — can you sum these values: 5000000000, 3000000000, 7000000000, 2500000000?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/evm-batch-value-sumWhen to prefer
Choose this endpoint when you need a fast, auditable, in-memory summation of EVM wei values with no external calls or data retention, especially for preflight checks before submitting batch on-chain transactions. Prefer it over doing client-side arithmetic when you need a tamper-evident SHA-256 evidence receipt of the input. It is bounded to 256 items and pure computation with no side effects.
Side effects
- Array exceeds 256 items limit — request rejected
- Individual value string exceeds 8192 characters — rejected
- Non-numeric or malformed wei string in array — computation error
- Empty array — may return zero total
- Network timeout or service unavailability — HTTP 5xx
