Keltner Channels Screener (Multi-Asset) API

healthy 4,110 Subscribers

Which markets are breaking out of their volatility-adjusted trend channel, computed live from Yahoo Finance (no key, nothing stored). Keltner Channels wrap a 20-day exponential average in bands set at two Average-True-Ranges above and below it — and unlike Bollinger Bands, whose width is statistical standard deviation, Keltner's width is the market's actual trading range. A close above the upper Keltner band is a trend-following breakout (riding strength), below the lower a breakdown, and price hugging a band signals a powerful, persistent trend. For a cross-asset, cross-sector universe — equity indices and sectors, gold, oil, commodities, bonds and crypto — this computes each asset's Keltner upper, middle and lower bands, where price sits inside the channel, and flags fresh breakouts. The screener endpoint returns the upside and downside Keltner breakouts across the board. The asset endpoint returns one market's Keltner card. The universe endpoint lists what is covered. The cross-asset Keltner-channel / volatility-trend screener cut — distinct from the Bollinger-Bands screener (standard-deviation width, mean-reversion), the bring-your-own-candle ATR API and the other indicator screeners.

ATR & Volatility Stops API

Live Average True Range and volatility-stop analytics that traders run to size stops to market noise, computed on demand from the OHLC candles you pass in — no key, no cache, nothing stored. The atr endpoint returns the Average True Range using Wilder's smoothing, its value as a percent of price, and the latest true range — the single number that tells you how much an instrument typically moves. The stops endpoint returns ATR-based stop levels: the Chandelier Exit for a long and for a short (highest high or lowest low offset by a multiple of ATR) and, if you pass an entry price, an ATR trailing stop with its distance in money and percent. The keltner endpoint returns the Keltner Channel — an EMA mid-line with ATR-scaled upper and lower bands — and where the last price sits. Because true range needs the full high, low and close, this is a different tool from closes-only indicator APIs and from single-coin volatility feeds: you supply the candles for any market — forex, stocks, crypto or commodities. Computed locally and deterministically, so it is instant and private. Ideal for stop placement, position sizing, breakout filters and risk dashboards. ATR uses Wilder's smoothing. Live, nothing stored. 3 compute endpoints. For closes-only indicators like RSI or MACD use a technical-indicators API.

Minds API

Read any public Minds channel and the platform's live hashtag trends — no key needed. Minds is an open-source, decentralised social network; this API returns a public channel's display name, bio, subscriber and subscription counts, lifetime impressions, Plus/Pro and verified flags and join date, plus the hashtags trending on Minds right now with their volume. Pass a username (the handle without the @). Data comes live from Minds' own public API — nothing cached, nothing stored. Distinct from the Mastodon/fediverse APIs — Minds runs its own platform. Built for social dashboards, creator analytics and trend monitoring.

Coub API

Live looping-video data from Coub, the social platform built around short, seamlessly looping video clips, served straight from Coub's public API — no key, nothing cached. The explore endpoint returns the trending feed (rising, hot or random coubs across the whole site), each with its title, view, like and recoub counts, duration, channel and tags, plus ready-to-use loop-preview image URLs at several sizes. The tag endpoint returns the newest coubs for a tag — cats, gaming, music — the hashtag feed of Coub. The channel endpoint returns a creator's profile (title, follower and recoub counts) together with their most recent coubs. Every clip comes back cleaned up: the watch URL, the channel handle, the human tags and several preview-image sizes. Everything is live from Coub, nothing stored. This is the looping-video discovery layer for any feed, meme, moodboard, embed or social app. Distinct from YouTube, Vimeo, Dailymotion and other video APIs — this is Coub's looping clips by trend, tag and channel. 3 endpoints, no key on our side.

Farcaster API

A live window into Farcaster, the decentralised social network, as an API via the public Warpcast feed. Look a user up by username or FID for their profile (followers, following, bio); pull a user's recent casts (posts) with their likes, recasts and replies; browse the channels people post in, ranked by followers, or filter them; or open a single channel. The on-chain social graph delivered as clean JSON for social, web3 and dashboard apps. Live data, no key. Distinct from Mastodon, Bluesky and other social platforms — this is Farcaster.
