SWIFT Code Lookup

Overview

Pass a SWIFT string to retrieve the institution's legal name, branch department, city, and two-letter country code. Alternatively, supply an institution name to search for associated SWIFT codes across multiple branches. The directory refreshes weekly and returns a total match count with an array of bank records.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/swiftlookup?swift=CHASUS33ARP", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		panic(err)
	}
	defer res.Body.Close()

	out, _ := io.ReadAll(res.Body)
	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

{
  "status": "ok",
  "error": null,
  "data": {
    "count": 1,
    "banks": [
      {
        "bank": "JPMORGAN CHASE BANK, N.A.",
        "city": "NEW YORK,NY",
        "branch": "ACCOUNT RECONCILIATION PROCESSING",
        "swift_code": "CHASUS33ARP",
        "country": "United States",
        "country_code": "US"
      }
    ]
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Use cases

Cross-Border Wire Verification

Before initiating an international wire, billing platforms verify the recipient's SWIFT code matches the intended legal entity and destination country.

Vendor Onboarding Form

Auto-fill the bank name, branch city, and country code as soon as a supplier enters their SWIFT code during payment registration.

Branch Code Discovery

Accounting software helps treasury operators locate missing branch SWIFT codes by querying institutional names across international divisions.

Bank Country Screening

Risk engines cross-check the SWIFT country code against sanction lists to flag transfers directed to prohibited financial jurisdictions.
