Trends API
Trend data from 804 sources, in your own code. Every trend TrendIntel tracks, labelled against its own usual level, with its AI brief, the companies and products rising with it, the narratives it belongs to and what public companies are telling the SEC.
Included with Pro: 20 keys, 60 requests a minute.
One call, one rising trend
Ask for the rising trend with the most momentum. Send your key in the Authorization header; everything comes back as JSON. This is the live answer, refreshed hourly.

velocity 0.5 means this week is 50% above the trend's usual week.
spread is the share of the last four weeks' signals from each kind of source.

What the API returns
21 resources in three groups. Each can be filtered, searched, sorted and paged, and links to the others: a trend to its brief, history and narratives; a filing to the holdings and insider trades in it.
Trends
- Every tracked trend with its label (new, rising, steady, cooling, returning, quiet), velocity, momentum and spread.
- AI briefs: what it is, why now, who is driving it, what to watch.
- Daily history and every label change, with when it started and ended.
- Narratives: groups of related trends moving together.
- Cross-source conviction: how many separate worlds point at a trend at once.
Entities and emerging trends
- Rising companies, products and people: mentions this week against the weeks before.
- Weekly history for every entity.
- Pairs mentioned together more than usual, and the communities they form.
- Emerging micro-trends: small clusters forming before any tracked trend covers them.
SEC filings and the Fed
- An index of filings: 10-K, 10-Q, 8-K, S-1, 20-F, DEF 14A, 424B, 13F, Form 4, 13D/13G and Form D, plus FOMC releases.
- Companies and products named in filings, with how favourably they are framed.
- AI themes: the risks and opportunities filers keep raising.
- 13F holdings, insider trades, activist and passive stakes, private placements.
What people build with it
Research and quant pipelines
Pull rising trends, label changes and their daily history into notebooks and models, and line them up with what companies disclose in SEC filings.
Market and product research
Watch what people are starting to talk about, which companies and products are being mentioned more, and which subjects are moving together.
Newsrooms and analysts
Find stories while they are still forming: trends that turned rising this week, micro-trends that no tracked trend covers yet, insider buying and activist stakes.
Dashboards and internal tools
Feed trend labels, momentum and AI briefs into your own dashboards, alerts and reports, refreshed every hour.
AI agents
Give an agent a key and the discovery document, and it can look up trends, read their briefs and follow them to related companies and filings on its own.
Investor relations and strategy
See which themes, risks and companies public filers keep raising, and whether the wider conversation is backing them up.
Limits and pricing
API access is part of the Pro plan. There is no separate API price.
If you leave Pro, your keys are kept and paused, and they work again when you return. Compare plans →
Questions
What is the TrendIntel Trends API?
A REST API that returns, as JSON, the trend data TrendIntel works out from 804 sources across research, developer communities, business, hiring, social platforms, news and government: every trend with its label (new, rising, steady, cooling, returning or quiet), its velocity against its own usual week, where it is being talked about, its AI brief, plus rising companies and products, narratives, emerging micro-trends and SEC filing data.
Which plan includes API access?
Pro, at $79 a month or billed annually. You can create up to 20 active keys, each with its own label, and make 60 requests a minute shared by all of them. If you leave Pro, your keys are kept and paused, and they work again when you come back.
Does the API include the original posts and articles?
No. The API serves what TrendIntel works out from them: the trends, labels, velocity, spread, AI briefs, entity counts and narratives. Each trend says which sources it comes from and in what share. Stock market prices are not included either.
How fresh is the data?
Trend numbers and labels are recalculated every hour. AI briefs are written nightly for the trends that need one, narratives are found weekly, and SEC filings arrive as they are published.
What happens when I go over the rate limit?
Requests past 60 in a minute get a 429 response with a Retry-After header that says how many seconds to wait. Every response carries X-RateLimit-Limit and X-RateLimit-Remaining, so a client can slow down before it gets there.
Can AI agents use the API?
Yes. The discovery document at /api/v1/discovery describes every resource, field, filter and relation in machine-readable form, so an agent can work out how to build requests by itself. Keep the key on the server side, never in a page or app other people can open.
Can I resell or republish the data?
No. Everything the API returns is TrendIntel content, which can't be reused for commercial purposes: use it for your own research, analysis and internal tools, but don't resell it, republish it, or build it into anything you offer to others. Our Terms of Service have the details.
