Included

Input review

Up to three representative JSON payloads plus their API or validation responses.

Written findings

Field-level issues, likely causes, prioritized fixes, and explicit assumptions.

Reproducible evidence

Sanitized test evidence, integrity manifest, archive hash, and local verification instructions.

One revision

One follow-up review of corrected samples submitted within seven days.

Process and result

Email a short problem description, sanitized samples, expected behavior, and actual response.
You receive a scope confirmation and payment instructions before work starts.
After confirmed payment and complete inputs, the target turnaround is two business days.
Delivery includes observable findings and acceptance criteria, not merely a generic report.

Acceptance criterion: each submitted sample is mapped to a documented finding or marked as having no reproducible technical issue, with evidence and a recommended next action.

Boundaries

This is a technical preflight review, not tax or legal advice.
It does not submit invoices to an IRP, certify compliance, or guarantee production acceptance.
No production access or secrets are required.
Additional payloads, implementation work, or live integration debugging require a separate written scope.

Payment

Payment is accepted in native USDC on Base after scope confirmation.
