}Lookup API
List token costs
Returns current pricing for every Etherfuse token: stablebonds (CETES,
TESOURO, USTRY, …) and principal tokens (MEXe, …). Each entry carries the
token’s cost in its denomination currency and in USD, plus a sources map
giving the exchange rate and derived USD cost from each FX provider, so you
can run your own oracle-safety checks.
Keyed by uppercased token symbol (CETES, MEXE). New tokens appear here
automatically once they are registered; nothing needs to change on your side.
This replaces GET /lookup/bonds/cost, which is deprecated and covers only
stablebonds.
Public, no API key required.
