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.
