Free Structured Products API

Structured note issuance parsed from SEC 424B2 and FWP filings. Issuer, underlyings, note type, coupon, and barrier per filing, refreshed every 30 minutes. This feed doesn't exist anywhere else for free.

Endpoints

GET

/api/markets/structured-products?issuer=&underlying=&noteType=&minCoupon=&maxCoupon=&days=

Recent filings, newest first, up to 200 rows. Filter by issuer substring, underlying symbol (SPX, NVDA...), note type (autocallable, buffered, barrier, income), coupon range in % (minCoupon/maxCoupon), and lookback days (max 365). Coupon filters match priced notes only. Preliminary filings carry null coupons and are excluded.

Honest Limits

Term extraction is best-effort. Preliminary filings often show no principal amount; coupon and barrier parse for most but not all filings.
The doc_url field always links the primary SEC document. Trust that over any parsed field.
History goes back 5 years (index metadata); parsed terms build forward from launch.
Updates track the EDGAR daily index, so weekends and market holidays are quiet.

Response Shape

Every endpoint returns the same JSON envelope: { data, updatedAt, source, docs }. The data field is an array of records with these fields:

Field	Type	Description
id	number	Row id; with filedAt it forms the cursor for paging
accessionNo	string	EDGAR accession number, unique per filing
issuer	string	Filing entity (BofA Finance, Morgan Stanley Finance...)
formType	string	424B2 or FWP
filedAt	string (date)	Filing date, YYYY-MM-DD
pricingDate	string \| null	Pricing/trade date when stated
underlyings	string[] \| null	Parsed underlying symbols (SPX, NDX, NVDA...). Populated for priced notes; preliminary filings carry nulls
noteType	string \| null	autocallable, buffered, barrier, or income. Populated for priced notes; preliminary filings carry nulls
coupon	string \| null	Annual coupon %. Populated for priced notes; preliminary filings legitimately carry nulls (rate is blank before pricing, never 0)
capPct	string \| null	Maximum return as % of initial level when the note is capped
barrierPct	string \| null	Barrier/threshold as % of initial level. Populated for priced notes; preliminary filings carry nulls
principalUsd	string \| null	Aggregate principal when stated (final filings)
docUrl	string	Link to the primary SEC document

Rows are newest-first. All parsed term fields are nullable by design: they populate for priced notes, while preliminary filings carry nulls until pricing. The SEC document link is the source of truth.

Numeric values arrive as strings where precision matters (prices, rates); parse with your language's decimal type for accounting-grade math. Rate limiting is fair-use per IP; a 429 response includes a Retry-After header. No authentication or API key needed. Attribution is appreciated: xoomar.com/markets.
