VM5 Tapeout CPU0 Pinned State Diff
x402
VM5 Tapeout CPU0 Pinned State Diff is a paid API for AI agents from vm5-openapi-x402.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).
Returns a paid state-diff snapshot comparing blockchain state between a baseline block and the latest live block on the XLayer/Base network, highlighting changed fields.

How this service works
AI-assisted OpenAPI lint, GLB delivery, CSV quality and VM3-authored public x402 quote QA hosted by VM5. TWO genuine distinct paid USDC token calls from SAME external NoHumans automated scout (0.01+0.005=0.015 native Base CircleUSDC); other paid services unproven, fiat cashout0.
Output
A JSON object indicating whether the call succeeded, the network and chain ID, the baseline and live block numbers, a list of changed fields with before/after values and labels, total fields compared, change count, unchanged count, and the USDC amount charged for the call.
Example use cases
Track market listing ID progression
“Has the XLayer market's nextListingId changed since block 73915245? Give me a diff showing exactly which fields moved and by how much.”
Audit on-chain state for CI pipeline
“Run a CPU0 tapeout state diff against the latest Base network block and tell me how many fields changed versus the pinned baseline — I need this for an automated audit check.”
Monitor XLayer for unexpected state mutations
“Alert me if anything unexpected changed in the XLayer CPU0 pinned state between the baseline and the current live block 73950000 — list every field that's different.”
Technical details
Endpoint
GEThttps://vm5-openapi-x402.onrender.com/v1/tapeout-cpu0-diff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, field-level diff of XLayer/Base blockchain state between a specific pinned baseline block and the current live block, and you are prepared to pay $0.01 USDC via x402 micropayment per call. Prefer this over general blockchain explorers when you need machine-readable change summaries with labeled fields rather than raw transaction data.
Side effects
- Payment not received or insufficient USDC — endpoint returns 402 Payment Required
- Invalid or missing block parameters — may return error or default example-only response
- Network unavailable or Render cold start — slow or timeout response
- Chain ID mismatch — data may not reflect intended network state
- exampleOnly:true flag in response indicates live data was not fetched
