Delx Commerce — EVM Blob Count Check
x402
Delx Commerce — EVM Blob Count Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Validates whether a given EVM blob count is within a specified maximum limit, returning a bounded pass/fail result with verifiable evidence.

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 with the original inputs (blob_count and maximum), a boolean within_limit field, an overall status (pass/fail), and an evidence block containing a SHA-256 hash of the input, a flag confirming no data retention, and a count of external calls made (always 0).
Example use cases
EVM transaction preflight validation
“I'm about to send an EVM transaction with 3 blobs and the network allows a maximum of 6 — can you do a quick preflight check to confirm my blob count is within the limit?”
Agent guardrail before blob submission
“Before my agent submits the next EVM blob batch, check whether 5 blobs stay within the maximum of 6, and give me verifiable evidence of the check.”
Automated EVM blob limit monitoring
“My pipeline is about to push 7 blobs but the cap is 6 — run the EVM blob count check right now so I know if it will be rejected before we try.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/evm-blob-count-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, trustless, and verifiable preflight check that a given EVM blob count does not exceed a specified maximum — especially in agentic pipelines where auditability (SHA-256 evidence hash, no data retention) and pay-per-call micropayment (no signup required) are priorities. Prefer this over custom logic when you need tamper-evident proof of the check result.
Side effects
- Missing required parameters (blob_count or maximum) result in a validation error
- Non-integer input types cause a schema rejection
- Payment not received or incorrect USDC amount leads to 402 response before computation
- Malformed request body returns a 400 error
