### Tool changes

- 2026-10-17 `register_signing_key` changed (description, inputSchema) **meaning changed**
  - before: Registers an RSA public key (2048-bit or larger, PEM) used to sign payment-decision requests. Keys are immutable per tenant; rotate by registering a new key_id.
  - after: Registers an RSA public key (2048-bit or larger, PEM) used to sign payment-decision requests. Keys are immutable per tenant; rotate by registering a new key_id. Returns key_id and registered=true. Use before decide_supplier_payment and use the same tenant/paying wallet for registration and decision. This is not a supplier check, API-key creation or payment authorization. Keep the RSA private key local; a conflicting existing key_id returns a conflict. Inspect and approve the registration fee before calling.
- 2026-10-17 `decide_supplier_payment` changed (description, inputSchema)
  - before: Flagship. Independent third-party decision for an Irish supplier invoice. Runs five gates (CRO status NORMAL, EU VIES VAT, payee-name and IBAN check, PO/GRN/invoice 3-way match, RSA signature) and returns exactly one of EXECUTE_PAYMENT, REJECT_PAYMENT or FLAG_FOR_HUMAN_REVIEW with per-check results, reason codes and a confidence score. The legacy CONFIRMATION_OF_PAYEE result means a payee-name comparison with the CRO legal name and IBAN validation, not bank Confirmation of Payee. ERP_THREE_WAY_MATCH compares caller-supplied documents, not independently verified ERP records. Decides only; never moves money. Register a signing key first via /v1/agent-keys.
  - after: Flagship. Independent third-party decision for an Irish supplier invoice. Runs five gates (CRO status NORMAL, EU VIES VAT, payee-name and IBAN check, PO/GRN/invoice 3-way match, RSA signature) and returns exactly one of EXECUTE_PAYMENT, REJECT_PAYMENT or FLAG_FOR_HUMAN_REVIEW with per-check results, reason codes and a confidence score. The legacy CONFIRMATION_OF_PAYEE result means a payee-name comparison with the CRO legal name and IBAN validation, not bank Confirmation of Payee. ERP_THREE_WAY_MATCH compares caller-supplied documents, not independently verified ERP records. Decides only; never moves money. Register a signing key first via /v1/agent-keys. Use this for the complete signed invoice/PO/GRN workflow, not verify_supplier_payment's separate identity/VAT contract or get_verification retrieval. Provider uncertainty requires review, not execution; retain independent payment approval. Supply a stable transaction_id for retries and never automatically repay.
- 2026-10-17 `check_three_way_match` changed (description, inputSchema) **meaning changed**
  - before: Checks that a purchase order, goods receipt and invoice agree on supplier, currency, amount, line items, unit prices and quantities received. Stateless; you attach the documents. Checks caller-supplied documents, not independently verified ERP records.
  - after: Checks that a purchase order, goods receipt and invoice agree on supplier, currency, amount, line items, unit prices and quantities received. Stateless; you attach the documents. Checks caller-supplied documents, not independently verified ERP records. Returns PASSED or FAILED and a reason code; no CRO/VIES lookup, signature validation or bank transfer is performed by this tool. Use decide_supplier_payment when document matching must be combined with supplier identity, VAT, payee and signature checks. Requires an explicitly approved service fee.
- 2026-10-17 `check_company` changed (description, inputSchema)
  - before: Looks up an Irish company by CRO number in the Companies Registration Office open data. PASSED only if the company status is NORMAL; dissolved, liquidated or unknown companies FAIL. Returns the registered name. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.01 USDC with explicit approval.
  - after: Looks up an Irish company by CRO number in the Companies Registration Office open data. PASSED only if the company status is NORMAL; dissolved, liquidated or unknown companies FAIL. Returns the registered name. Use a CRO company number, not a company name or VAT number. Source uncertainty returns UNAVAILABLE, not a pass. Use check_vat for VIES registration, verify_supplier_payment for claimed-name/identity reconciliation, or decide_supplier_payment for a complete signed invoice decision. No invoice is approved here. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.01 USDC with explicit approval.
- 2026-10-17 `check_vat` changed (description, inputSchema)
  - before: Validates the Irish VAT number format and check letter, then confirms registration live with EU VIES. Returns PASSED, FAILED or UNAVAILABLE (VIES outage) with a reason code. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.01 USDC with explicit approval.
  - after: Validates the Irish VAT number format and check letter, then confirms registration live with EU VIES. Returns PASSED, FAILED or UNAVAILABLE (VIES outage) with a reason code and available consultation/audit evidence. Use for one VAT number, not company-name matching or invoice approval. check_company checks CRO status; verify_supplier_payment reconciles claimed supplier identity and VAT; decide_supplier_payment runs the full signed invoice workflow. An outage is uncertainty, not invalid registration; do not auto-pay to retry. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.01 USDC with explicit approval.
- 2026-10-17 `check_iban` changed (description, inputSchema)
  - before: Cheapest call. Validates an IBAN (ISO 13616 mod-97 checksum, length and country) before you pay it. Returns PASSED or FAILED with a reason code. Irish (IE) IBANs pass by default. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.005 USDC with explicit approval.
  - after: Cheapest call. Validates an IBAN (ISO 13616 mod-97 checksum, length and country) before you pay it. Returns PASSED or FAILED with a reason code. Irish (IE) IBANs pass by default. Use only for bank-account identifier syntax/country checks, not account ownership, bank Confirmation of Payee or supplier identity. Use check_vat for VAT registration, check_company for CRO status, and decide_supplier_payment for the complete signed invoice decision. No bank transfer occurs. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.005 USDC with explicit approval.
- 2026-10-17 `get_verification` changed (description, inputSchema) **meaning changed**
  - before: Retrieve a verification result belonging to the authenticated tenant. Requires the verification.read scope.
  - after: Read an existing identity/VAT verification created by verify_supplier_payment (POST /v1/verifications). Supply its returned verification_id UUID, not a request_id, transaction_id, invoice number or A2A task ID. Returns the stored RELEASE/REVIEW/BLOCK/INSUFFICIENT_EVIDENCE result without rerunning registry checks. The same authenticated tenant must own the result: use the original paying wallet for x402, or an authorized bearer token with verification.read scope. Missing or other-tenant IDs return not found. This does not retrieve decide_supplier_payment decisions and does not create a verification. Retrieval has its own service fee; inspect terms and obtain spending approval before paying. Do not retry payment automatically or infer invoice-payment authorization from a stored advisory result.
- 2026-10-17 `verify_supplier_payment` changed (description, inputSchema) **meaning changed**
  - before: Verify a supplier's identity and VAT registration and return the advisory decision. Identity registry checks are routed to the Irish CRO for IE only. VAT is verified independently through EU VIES. Requires the verification.submit scope. transaction, customer_assertions and payment_destination are only evaluated when payment checks are enabled on the service; otherwise they may be omitted.
  - after: Use for supplier identity and VAT reconciliation, not the full signed five-gate invoice decision. Reconciles the claimed legal name, company registration number and VAT number against the Irish Companies Registration Office (IE) and the EU VIES VAT service, and returns an advisory RELEASE, REVIEW, BLOCK or INSUFFICIENT_EVIDENCE decision with per-check results and reason codes plus verification_id. Use decide_supplier_payment for the signed invoice/PO/GRN workflow, individual check tools for one check, and get_verification only to retrieve this stored result. This creates a verification and may call external sources; it never executes or authorises a bank payment. Requires explicit x402 service-fee approval or an authorized bearer token; do not automatically retry paid calls.
- 2026-10-17 `check_company` changed (description)
  - before: Looks up an Irish company by CRO number in the Companies Registration Office open data. PASSED only if the company status is NORMAL; dissolved, liquidated or unknown companies FAIL. Returns the registered name.
  - after: Looks up an Irish company by CRO number in the Companies Registration Office open data. PASSED only if the company status is NORMAL; dissolved, liquidated or unknown companies FAIL. Returns the registered name. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.01 USDC with explicit approval.
- 2026-10-17 `check_vat` changed (description)
  - before: Validates the Irish VAT number format and check letter, then confirms registration live with EU VIES. Returns PASSED, FAILED or UNAVAILABLE (VIES outage) with a reason code.
  - after: Validates the Irish VAT number format and check letter, then confirms registration live with EU VIES. Returns PASSED, FAILED or UNAVAILABLE (VIES outage) with a reason code. Free: 10 attempts per UTC day per IP, shared REST/MCP; failures count. Then 0.01 USDC with explicit approval.
