Endpoints

Method	Path	Description
GET	`/fx/rates`	List stored exchange rates for the tenant
POST	`/fx/rates`	Store a manual exchange-rate override

Store a manual rate

rate means 1 base_currency = rate quote_currency; the inverse is derived.

curl -X POST https://ledga.io/api/v1/fx/rates \
  -H "Authorization: Bearer sk_xxxxxxxx_your_secret" \
  -H "Content-Type: application/json" \
  -d '{ "base_currency": "EUR", "quote_currency": "USD", "rate": "1.081" }'

Convert

curl "https://ledga.io/api/v1/fx/convert?from=EUR&to=USD&amount=100.00" \
  -H "Authorization: Bearer sk_xxxxxxxx_your_secret"

Rules

GET /fx/rates/{from}/{to} resolves manual override → live provider → stored fallback.
effective_at defaults to now; expires_at ends an override.
GET /fx/rates/{from}/{to}/history lists stored rates for the pair, newest first.
Conversions inside a string use POST /strings/{code}/convert.
