Record the forex rate for one hour-long window
PUT /fx/rates
Record the forex rate for one hour-long window: rateMicros millionths of a quote unit per base unit, in force from the hour-aligned windowStart.
Auto-priced catalogs read the newest window at or before the current hour; re-recording a window replaces its figure (a correction, journalled like the first). Appends inventory.fx-rate-recorded. Idempotent by content: a retry that changes nothing is acknowledged and appends nothing.
Access
Requires catalogs:write.
How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.
Retries
Idempotent by content: a retry that changes nothing is acknowledged and appends nothing.
Why every write carries a key: Idempotency and retries.
Facts appended
inventory.fx-rate-recorded
What a fact is: Facts and the journal.
AI agent tool
Agents call this as catalog_record_fx_rate (Catalog: Record FX rate), in the pricing toolset.
Connecting an agent: AI agents.

page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: inventory-manager.openapi.json. Base URL https://inventory.getmanifold.io.
