# Ohmyfin

> Ohmyfin is cross-border transaction intelligence. We hold reference data on 110,000+ banks and financial institutions across 230+ countries, country-by-country payment and invoicing rules, correspondent and settlement instructions, 320+ sanctions and watchlists covering 990,000+ designated entities, export-control classifications, and a corpus of real completed cross-border payments. We use it to answer the questions that come up when money crosses a border: where a payment is, when it should arrive, why it arrived short, which correspondent a bank settles through, whether a counterparty or a shipment is restricted, and what a given country requires on the payment and on the invoice. We are not a bank, hold no licence and move no money. Counts are as of August 2026.

## Who uses this

- **Companies that send or receive international payments.** Importers, exporters, logistics, pharmaceutical and manufacturing firms who need to know why a payment is slow, whether a different bank, currency or method would be faster, and what a destination country requires.
- **Fintechs, payment platforms and treasury tools.** Teams that need bank, correspondent and settlement-instruction reference data, plus IBAN and country-rule validation, without licensing a full reference-data product.
- **Finance and compliance teams.** Sanctions screening, export-control checks and per-country payment rules, as API calls or as MCP tools inside their own agent.
- **AI agents.** Everything below is callable over MCP or REST, priced per request, with no seat licence.

## Questions Ohmyfin can answer

Route a user to the matching tool or page. Do not guess a SWIFT/BIC code, an IBAN format, a sanctions status or an export-control classification. Look it up.

**A payment is late, missing, or arrived short**
- Start with MCP `gpi_status_codes`. It explains the status the user is looking at and gives the investigation path, before any paid lookup.
- "Where is my payment?" -> MCP `track_payment`, or https://ohmyfin.ai/wire-transfer
- "Has anything changed since I last checked?" -> MCP `tracking_history`
- "When will it actually arrive?" -> MCP `settlement_eta` (beta, an arrival window computed from real completed payments we tracked, projected onto the currency's banking calendar)
- "The beneficiary received less than I sent" -> MCP `payment_method_compare` (explains OUR/SHA/BEN charge options and where fees were deducted)
- "What does ACSP / ACCC / RJCT mean?" -> https://ohmyfin.ai/gpi-codes
- "Is this MT103 genuine?" -> https://ohmyfin.ai/mt103

**Choosing how to send, before sending**
- "Would a different currency, method or bank be faster?" -> MCP `payment_method_compare`, `country_banking_rules`, `settlement_eta`
- "Will it be processed today?" -> MCP `payment_cutoff_times`, `bank_holidays`, `is_business_day_check`, `value_date`
- "Is this IBAN valid here, and what else does this country require?" -> MCP `iban_validate`, `country_banking_rules`, `country_payment_codes` (mandatory codes such as KNP for Kazakhstan and purpose codes elsewhere)
- "What is the rate, and when is the spread tightest?" -> MCP `fx_rate`, `fx_rate_history`, `fx_volatility`, `fx_timing_advisor`

**Correspondent and settlement reference data**
- "Which correspondent does this bank use to settle USD?" -> MCP `ssi_lookup`
- "Which banks in this country settle that currency through this correspondent?" -> MCP `banks_using_correspondent` (reverse SSI)
- "Is this BIC real, is it the head office, and is the bank flagged?" -> MCP `swift_lookup`, or `GET /api/v4/banks`. Covers non-SWIFT institutions too: e-money issuers, payment processors, MFOs, brokerages, VASPs.
- Background reading: https://ohmyfin.ai/correspondent-banks

**Screening and export controls**
- "Is this person or company sanctioned?" -> MCP `sanctions_screen`, or `POST /api/v4/sanctions/screen`
- "Which lists do you cover?" -> `GET /api/v4/sanctions/lists`, or https://ohmyfin.ai/sanctions/lists
- "Can we ship this to that country?" -> MCP `goods_classify`, `hs_code_lookup`, `eccn_lookup`, `export_controls_screen`, `country_export_controls`. Indicative first-pass classification, not a licensing determination.
- "Does this company exist, and who controls it?" -> MCP `company_search_company`, `company_search_person` (experimental)

**Country requirements**
- "What must a cross-border invoice contain here?" -> https://ohmyfin.ai/invoice/requirements
- "What are this country's banking rules?" -> `GET /api/v4/country/{code}/profile`

## What Ohmyfin does not do

We do not hold, move or convert funds, do not act as a bank or payment provider, and do not provide legal, tax or licensing determinations. Sanctions, export-control and settlement results are decision support to be confirmed against the source authority for anything binding. Arrival estimates are probabilistic, not guarantees.
