Integrate this Bolta API into the current project. Verify account holders, including fixed-amount virtual accounts. Read the official documentation first and propose an implementation that fits the project's language and structure. https://docs.bolta.io/llms.txt https://docs.bolta.io/docs/api-introduction/quickstart https://docs.bolta.io/docs/api-introduction/bank-account-holder https://docs.bolta.io/docs/api-introduction/pricing Prerequisites and scope: - Fixed-amount virtual accounts require the correct designated amount. - See the official documentation for supported banks. Bank account holder lookup: KRW 50 per successful account lookup No charge for accounts whose holder cannot be found or whose lookup fails. No subscription plan restriction applies. Read the API key from a server environment variable. Do not ask for secrets in chat. Start with the documented test key and test inputs. Test goals: Test ordinary and fixed-amount virtual account success, amount mismatch, and lookup failure. Distinguish duplicate entries within one request from separately billed repeat requests. Do not invent undocumented features or responses. Identify open questions and summarize test results and production-readiness steps.
