What do you want to build?
Start with a research workflow and a spreadsheet, or follow an API guide to build your own application.
Start with a research workflow
Choose a starting point, review the evidence, and keep a workbook you can rebuild.
Central-bank policy comparison
Compare US and euro-area policy rates alongside EUR/USD.
Open workflowRelease and revision review
Inspect retained US inflation releases, values and publication evidence.

Five practical paths
Start with the outcome, not the endpoint list.
Selected: Troubleshoot a request
Path 1
Fetch macro data
Retrieve a clean time series and keep the source and quality metadata beside it.
Path 2
Plan release jobs
Use the release calendar to run targeted jobs around known publication times.
Path 3
Measure surprises
Join pre-release forecasts to the published value without introducing lookahead bias.
Path 4
Receive live updates
Use SSE as an invalidation signal, then fetch the complete record from REST.
Path 5
Build a macro model
Turn a small group of related indicators into a source-labelled currency scorecard.
Your 14-day API trial
Move from first request to a job worth keeping.
The goal is not to visit every product page. It is to complete useful authenticated API work, return on another day, and leave with a repeatable dataset or application workflow.
Day 0
Prove access
Create the key, complete one authenticated request, and save the first response with its metadata.
Open step →Days 1-2
Make the request dependable
Resolve authentication or filter problems and turn the first script into a named repeatable job.
Open step →Days 3-4
Add release timing
Use the calendar as a second endpoint family and schedule the next useful API run.
Open step →Days 5-7
Build the research output
Add expectations or a small group of macro series, then produce one saved comparison, table, or scorecard.
Open step →Days 8-10
Automate updates
Choose scheduled REST, SSE, or webhooks and complete another successful API run on a different day.
Open step →Days 11-13
Harden the client
Add timeouts, bounded retries, response validation, credential-safe logging, and stale-data monitoring.
Open step →Day 14
Review evidence
Confirm the API supplies a repeatable job your team will keep, then choose the next dataset or application workflow.

Diagnose a failed or empty response
Inspect the status and a short error body, then follow the matching fix. Never paste an API key or a full authenticated URL into a support message.
Working example
Keep your key in FXMD_API_KEY; never paste it into source control.
import os
import requests
key = os.getenv("FXMD_API_KEY", "").strip()
if not key:
raise RuntimeError("FXMD_API_KEY is not set")
response = requests.get(
"https://api.fxmacrodata.com/v1/announcements/eur/inflation",
params={"limit": 1},
headers={"X-API-Key": key},
timeout=20,
)
print(response.status_code, response.text[:300])Expected result: A 200 confirms the key and path work. A 401 or 403 points to authentication or access, a 404 to the path, and a 429 to request pacing.

Troubleshooting and production guidance
Use these guides when a response fails, returns no data, or needs production controls such as caching, timeouts, retries, and event delivery.
| Guide | Use it when | Start |
|---|---|---|
| Diagnose a failed or empty response | Separate authentication, access, path, rate-limit, and data-availability problems without exposing your key. | Open guide → |
| Make an API client production-ready | Add timeouts, bounded retries, caching, conditional requests, and the right delivery pattern. | Open guide → |
