Scope one comparison pilot

Start with one recurring exception between order, payment and delivery records. This is an enquiry for a possible scoped integration, not a paid checkout or a promise that every workflow is supported. Inspect the free example first.

What to bring

Describe the exception, systems and record types involved, approximate volume, current review time, the expected result, required timing and any purchasing or data-handling requirements. Start with a description or synthetic records. Do not email credentials, raw payment signatures, personal data or unredacted customer records; agree a suitable sample-sharing method before sharing sensitive information.

Proposed deliverables

How acceptance is agreed

Agree expected mismatches and missing-evidence cases before work starts. Acceptance means the agreed sample set produces the expected findings and a report your team can retain and reproduce. Measure review time against your own baseline if that is a goal; no saving is assumed.

Timing and price

After reviewing the workflow, we confirm whether it is supported and propose a written scope. Initial pricing experiment: $500–$1,500 for one bounded workflow, one agreed dataset and one exception report. This is a written quote, not verified demand or a standing subscription. The quote must specify the deliverables, sample handling, start date, delivery date, acceptance criteria, price, currency and payment terms before either side commits. Sending an enquiry creates no payment obligation. Settlement-service billing is not activated for this synthetic evaluation workflow. Separate API checks settle per call in Base L2 USDC / Circle EURC (x402 v2); operators and enterprise workflows purchase instant ck_live_ card quota keys or $99 batch packs via Stripe (Operated by JUANA LIMITED, UK Co. No. 14043409). No fee is charged by this synthetic evaluation workflow.

Comparison is not independent proof of authorization, settlement, delivery or quality. Automatic payment, independent delivery verification, aggregate-budget enforcement and production scale are outside this comparison pilot.

Escalation for ambiguous paid outcomes. Preserve the original operation, authorization and any transaction reference. Use the documented recovery contract for the exact route and client version; do not create a fresh payment to resolve an unknown outcome. If no supported recovery path is available, contact hello@code402.dev with redacted evidence, never a private key or recovery secret. A receipt authenticates its recorded claim, not every underlying event.
