# Introduction [OpenFinTech.io](https://openfintech.io) is an open database that comprises of standardized primary data for FinTech industry.
It contains such information as geolocation data (countries, cities, regions), organizations, currencies (national, digital, virtual, crypto), banks, digital exchangers, payment providers (PSP), payment methods, etc.
It is created for communication of cross-integrated micro-services on "one language". This is achieved through standardization of entity identifiers that are used to exchange information among different services.

Powered by [Paymaxi](https://www.paymaxi.com) # Get Started If you use [POSTMAN](https://www.getpostman.com) or similar program which can operate with swagger`s files - just [download](https://docs.openfintech.io) our spec and [import it](https://www.getpostman.com/docs/importing_swagger). Also you can try live [API demo](https://api.openfintech.io). ## Overview The OpenFinTech API is organized around [REST](https://en.wikipedia.org/wiki/Representational_state_transfer). Our API has predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors.
API is based on [JSON API](http://jsonapi.org) standard. JSON is returned by all API responses, including errors, although our API libraries convert responses to appropriate language-specific objects.
JSON API requires use of the JSON API media type (`application/vnd.api+json`) for exchanging data.
### Additional Request Headers #### ACCEPT HEADER Your requests should always include the header: ```curl Accept: application/vnd.api+json ``` ## Authentication To use OpenFinTech API no needed authorization. ## Versioning When we make changes to the API, we release new, dated versions. The current version is **2017-08-24**. Read our [API upgrades guide]() to see our API changelog and to learn more about backwards compatibility. ## Pagination OpenFinTech APIs to retrieve lists of banks, currencies and other resources - paginated to **100** items by default. The pagination information will be included in the list API response under the node name `meta` - contains information about listed objects [`total` - contains information about total count of listed objects, `pages` - count of pages], `links` - contain links to navigate between pages [`first` - link to first page, `prev` - link to previous page, `next` - link to next page, `last` - link to last page].
By default first page will be listed. For navigating through pages, use the page parameter (e.g. `page[number]`, `page[size]`).
The `page[size]` parameter can be used to set the number of records that you want to receive in the response.
The `page[number]` parameter can be used to set needed page number.
Example of response: ```json { "meta": { "total": 419, "pages": 42 }, "links": { "first": "/v1/{path}?page[number]=1&page[size]=10", "prev": "/v1/{path}?page[number]=39&page[size]=10", "next": "/v1/{path}?page[number]=41&page[size]=10", "last": "/v1/{path}?page[number]=42&page[size]=10" } ``` ### Sorting OpenFinTech\`s API supported query parameter to sort result collection [e.g. `?sort=code`]. Information about available parameters may be found in the endpoint description. Positive parameter [e.g. `?sort=code`] points to ascending sorting, negative [e.g. `?sort=-code`] - to descending sorting. Also, supported multiple sorting parameters [e.g. `?sort=code, -name, id`, etc.] ```curl https://api.openfintech.io/v1/countries?sort=name,-area ``` ### Filtering Filtering provided by unique query key `filter[*filtering_condition*]`. Information about available parameters may be found in the endpoint description. ```curl https://api.openfintech.io/v1/countries?filter[region]=europe ``` ## Images OpenFinTech provides two types of images: icons and logos. To get one of those types you should to use next url pattern: ``` curl https://api.openfintech.io/v1/{path}/{id}/{icon/logo} ``` Also, images can be resized by adding next parameters: `h={height}&w={width}`. For example, you want to get organization icon with width equals to 20 pixels: ``` curl https://api.openfintech.io/v1/organizations/{id}/icon?w=20&h=20 ``` If argument height or width is missing API returns original image with real sizes. ## Errors API uses conventional HTTP response codes to indicate the success or failure of an API request. In general, codes in the `2xx` range indicate success, codes in the `4xx` range indicate an error that failed given the information provided (e.g., a required parameter was omitted, etc.), and codes in the `5xx` range indicate an error with OpenFinTech's servers (these are rare). | Code | Description | |------|-------------| | 200 - OK | Everything worked as expected. | | 400 - Bad Request | The request was unacceptable, often due to missing a required parameter. | | 401 - Unauthorized | No valid API key provided. | | 402 - Request Failed | The parameters were valid but the request failed. | | 404 - Not Found | The requested resource doesn't exist. | | 409 - Conflict | The request conflicts with another request (perhaps due to using the same idempotent key). | | 429 - Too Many Requests | Too many requests hit the API too quickly. We recommend an exponential backoff of your requests. | | 500, 502, 503, 504 - Server Errors | Something went wrong on OpenFinTech's end. (These are rare.) |
