Cross-Border Payment Prevalidation Readiness Scorer

Validates a cross-border payment bundle across five dimensions: IBAN mod-97 check digit, BIC format (ISO 9362), UETR UUIDv4 format, LEI 20-character format presence, and PostalAddress24 structure (including silent-fail AdrLine duplication detection). Emits a ready boolean for the gated prevalidation chain.

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only. IBANs and BICs are structural identifiers processed for format validation only, never as PII.
Payment Identifiers (Required)
ISO 13616. Spaces removed before validation. Mod-97 check digit verified.
ISO 9362: 4-char bank + 2-char country + 2-char location [+ 3-char branch].
SWIFT UUIDv4: 8-4-4-4-12 hex, version nibble = 4, variant nibble in {8,9,a,b}.
20-char ISO 17442 (A-Z, 0-9). Format presence check only (not full mod-97).
PostalAddress24 (Beneficiary Address)
Structured street name. Used for silent-fail duplication detection against AdrLine.
Structured city. Duplication in AdrLine = silent STP rejection.
Exactly 2 uppercase letters.
Optional. CBPR+ Nov 2026: max 2 lines x 70 chars. Duplication of structured fields causes silent-fail.

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `prevalidation_readiness_scorer`. Task: Aggregate CBPR+ pre-validation readiness check for a single pacs.008 payment instruction.
Call it with arguments: {"policy_parameters":{"iban":"DE89370400440532013000","bic":"DEUTDEFFXXX","lei":"00000000000000000001","uetr":"550e8400-e29b-41d4-a716-446655440000","address_street_name":"Kaiserstrasse","address_building_number":"29","address_post_code":"60311","address_town_name":"Frankfurt","address_country":"DE"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
PII rule: All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.
