Code402 is the product and commercial home. HCRB is its API and tools service. Both are operated by Juana Limited.

Pricing

Start with one inspectable exception report

Find mismatches between order, payment and delivery records. An inspectable exception report from the records you supply.

Evaluation price: $0. The synthetic workbench and stateless supplied-record comparison are free to evaluate. No wallet or payment is required.

Settlement-service billing. 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. A paid transaction-wide service requires agreed scope and passed acceptance tests; it is not sold by this page.

Scope. Comparison is not independent proof of authorization, settlement, delivery or quality. The comparison handler is stateless and does not execute payments.

Need this in your workflow?

Enquire about one scoped comparison pilot. Proposed deliverables are a field mapping, reproducible request, JSON exception report and handover for an agreed sample set. Acceptance checks expected mismatches and missing evidence. 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. Scope, timing, currency and payment terms require a written quote before any commitment.

Existing API access is a separate legacy offer

Existing identifier checks and other tools retain their current per-tool prices. The live HTTP 402 challenge supplies the amount, asset, network, recipient and resource to inspect before signing; there is no universal flat price for the catalog. A daily free allowance is available without a wallet. Check the current allowance and scope before use.

Published integration limitation: the current LangChain dependency can report receipt_verified: false for the extended XDR-1 form. Do not treat that output as verified evidence. The receipt-verification fix is staged, not yet published; free verification and public verifying keys remain available.

Read the current legacy plan terms and tool catalog. Do not infer pack consumption, expiry, billing period or features from another offer. Available payment methods are shown by the live checkout; no payment is required for the comparison workflow.

Multi-currency checkout is supported across 25 fiat currencies and 7 on-chain rails. Explore 16 verified moats on the machine surface.

Receipt verification remains free. Where an API returns a receipt, verify its signature and request/result binding. An absent receipt remains absent, not independently verified.

For a scoped integration or organisational purchasing, discuss the workflow. No service-level percentage, automatic debit or unshipped feature is included by implication.
