Built for teams that need data in production, not a demo endpoint.
Broad APIs can be useful. AmericanETP is more focused: repeatable ETF and index files with the fields, timing and archives a data desk needs.
Stable CSV delivery
Flat files are easier to inspect, version and automate when your workflow already expects repeatable file imports.
Field-level clarity
Constituent and fundamentals definitions are public before you subscribe, so your team can map the schema early.
Archive access
Annual subscribers can work with historical constituent list archives beginning as early as July 2009.
Evaluation Path
Check the exact file structure before you commit.
Start with current files, review field definitions, then choose internal use or distribution rights once the data fits your workflow.
Inspect files
Review ConstituentData42.csv, ETFDATA42.csv, Fundamentals.csv and coverage lists using real current data.
Map fields
Use the public definitions to align holdings, weights, identifiers, classifications and fundamentals with your system.
Automate delivery
Subscriber HTTP and FTP access support repeatable daily imports after the overnight update cycle.
Useful where generic ETF endpoints get thin.
AmericanETP is made for workflows that care about coverage, fields, timing and rights, not just a quick quote lookup.
Portfolio analytics
Pull holdings, weights, identifiers, sectors and fundamentals into internal analytics without rebuilding sponsor collection.
Data product operations
Use distribution or website rights when ETF and index data needs to support a client-facing workflow.
Research and monitoring
Track coverage, new ETF additions, constituent changes and breadth reports across the covered universe.

Frequently asked questions
Is AmericanETP an ETF data API?
AmericanETP primarily delivers ETF and index data as daily CSV files through subscriber HTTP and FTP access. For many data teams, that works better than a broad API because the files are simple to inspect, archive and load into existing systems.
What ETF data is included?
The file set includes current constituent data, ETF-level fundamentals, coverage lists, individual constituent lists and historical archives for qualifying subscribers.
Can I test the files before subscribing?
Yes. Trial access opens real current files, not a frozen sample, so your team can check coverage, fields and delivery fit before choosing a subscription.
Who is this best for?
AmericanETP fits analysts, data vendors, developers and internal teams that need repeatable ETF and index constituent data in a clean file format.
Test the files with your own workflow.
Open current ETF and index files, check the fields, then decide whether an internal or distribution subscription fits.
