Greptile Summary

Corrected USD external account examples to match the UsdAccountInfo schema requirements. Changed invalid accountType: US_ACCOUNT to USD_ACCOUNT and added missing required fields countries and paymentRails in both customer and platform external account endpoints.

Changes:

• Fixed accountType discriminator from US_ACCOUNT to USD_ACCOUNT to match schema enum
• Added required countries: [US] field
• Added required paymentRails: [ACH] field
• Generated bundles (openapi.yaml and mintlify/openapi.yaml) correctly reflect source changes

Note: Similar issues exist in payment instruction examples in openapi/components/schemas/transactions/OutgoingTransaction.yaml, openapi/components/schemas/quotes/Quote.yaml, and openapi/webhooks/outgoing-payment.yaml (still using US_ACCOUNT instead of USD_ACCOUNT). Consider addressing these in a follow-up PR.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• All changes correctly align examples with schema requirements, fixing invalid discriminator value and adding missing required fields. Changes are documentation-only (OpenAPI examples) with no runtime impact. Generated bundles are properly updated.
• No files require special attention
