CAPABILITY PROFILE
What the Fixer integration exposes
The Fixer Agent App exposes 3 provider-backed actions for finance and data work. Its current contract lets an authorized agent retrieve historical fixer exchange rates for a specific date, retrieve the latest fixer exchange rates for all or selected currencies, and retrieve all supported fixer currency symbols and their full names. These operations are called through Working Machines as typed capabilities rather than through browser navigation or copied UI steps.
A connection uses API key. Before execution, the agent can inspect the selected action, its required fields, declared scopes, and expected output contract. Provider credentials remain inside the Working Machines runtime; the calling agent receives the capability and its structured result, not the underlying secret.
For reliable operation, start with the narrowest action that satisfies the task, resolve stable provider identifiers before changing state, and validate the returned object or status after execution. Availability still depends on the connected Fixer account, granted provider permissions, workspace policy, region, plan, and upstream API behavior.

PROVIDER-SPECIFIC WORKFLOWS
Jobs this Agent App can support
Inspect Get Historical Rates
Retrieve historical Fixer exchange rates for a specific date. Use this as a bounded discovery step, retain the returned identifier, and avoid expanding the read beyond the task's stated scope.
get_historical_ratesVerify with Get Latest Rates
Retrieve the latest Fixer exchange rates for all or selected currencies. Compare the returned provider state with the intended outcome and preserve stable IDs or canonical links in the run record.
get_latest_ratesSAFETY BOUNDARY
Operate Fixer with explicit limits
- Authorize Fixer with API key and grant only the provider access required by the selected actions.
- The current action names appear read-oriented, but returned Fixer data may still be sensitive and should be minimized before it enters model context.
- Do not infer permission from catalog visibility. Workspace policy, connection identity, and upstream authorization still govern execution.
- No provider scope string is declared on the sampled actions. Verify the connected account's actual permissions in Fixer rather than assuming unrestricted access.
- After a call, inspect the structured result and execution record before reporting that the Fixer task completed successfully.
CONNECTION MODEL
API key
Fixer API key used as the access_key query parameter. Get it from your Fixer dashboard: https://fixer.io/dashboard.
Working Machines stores provider credentials behind the execution boundary. An agent can use an authorized connection identity, but catalog discovery alone does not reveal OAuth tokens, API keys, or provider secrets.

EVIDENCE AND AVAILABILITY
Provider reference
Action names, input fields, authentication types, and counts on this page are generated from the Working Machines provider catalog. Provider behavior, quotas, object semantics, account eligibility, and regional availability remain governed by Fixer.
