US Treasury Yields & Bond Data — Curve API

US Treasury Yields & Bond Data

US Treasury Yields & Bond Data is a NexGenData tool on Apify that returns daily yields from 1-month to 30-year, spreads and curve inversion from FRED and Treasury.gov.

US Treasury yield and bond public data — the curve, tenors and daily rates.

Factual public records — not financial, investment or compliance advice. Screening data is provided as-is for your own compliance program.

⚙️ Sample inputs

This is the Store example input — the same input Apify's automated check runs — so it is proven to return rows on the current build. Paste it into the input form, or send it through the API, CLI or a schedule:

{
  "tenors": [
    "2Y",
    "5Y",
    "10Y",
    "30Y"
  ],
  "date_range": "today",
  "include_historical": false
}

🔧 Input reference

Field	Type	Default	What it does
tenors	array	["2Y", "5Y", "10Y", "30Y"]	List of Treasury tenors to fetch. Supported values: 1M, 3M, 6M, 1Y, 2Y, 3Y, 5Y, 7Y, 10Y, 20Y, 30Y. Leave empty for the full curve.
date_range	string (today, last_30d, last_90d, ytd)	"today"	Range of historical observations to include. 'today' returns just the latest print, 'last_30d' / 'last_90d' / 'ytd' return full history per tenor.
include_historical	boolean	false	If true, emit one record per (tenor, date) for the selected date_range. If false, emit only the most recent record per tenor with rolling 1d/1w/1m/YTD change context.

💰 Pricing

Event	Price (USD)	When it is charged
Actor Start (apify-actor-start)	$0.01	Charged when the Actor starts running. Number of events charged depends on Actor memory (one event per GB, minimum one event).
Yield record (apify-default-dataset-item)	$0.1	Charged per Treasury yield record returned with tenor, yield, daily/weekly/monthly/YTD changes in bps, curve context.

Pay-per-event: you pay only for what the run delivers. A run that delivers nothing bills no result events (only the actor-start event, when the actor defines one). Example: a run that delivers 100 results costs 100 × $0.1 = $10.00 plus the start fee.
