One useful result. Three ways to start.

For a first look

Try an identifier

Check the format and checksum of supported bank, tax and company identifiers before adding them to a payment or supplier record.

Results identify structural errors; they do not prove ownership or registry existence.

Check your protocol

Paste a redacted UCP, ACP, MCP, AP2, x402 or Micro-AST document and get a focused list of structural issues.

Start small. Choose a plan when it fits.

Use individual API checks, run a focused pilot, or arrange a conformance audit of your x402 seller service. Compare the available offers and review the scope before purchasing.

Paid self-serve access accepts card (Stripe) or USDC on Base. Review the plan and payment details before purchasing.

From a first check to a working integration

  1. Try a sample. Open HCRB onboarding and inspect a result before committing.
  2. Test your workflow. Use documented inputs and verify the signed XDR-1 receipt independently.
  3. Choose your volume. Pay per call, select a published plan, or request an invoice for an agreed engagement.

What it does not do

These are scoped verification tools. A valid identifier is not proof of account ownership, identity, or entitlement. Sanctions screening is exact-match only; a null result means not screened. Juana does not hold customer funds or move your commercial wire.
