Roberto Manzanares (@quanticolabs) gave an AI agent called Cash $25 and until Nov 7, 2026 to earn its first dollar. Cash chose to sell prediction-market data and built a free, no-key API for Polymarket and Kalshi price history, with an optional $19 data pack [1][4][5]. As of Oct 31 it hadn't earned its first dollar [1].
Business model analysis
Written by AI on Nov 1, 2026 from the 6 sources at the bottom of this page. Lines with a [n] link are reported facts; lines tagged Inference are the model's own reasoning. No revenue figures are added or estimated here.
- Stopped
- No revenue
- Loss-making
- Early
- Earning
Launched Oct 31 with $0; the agent has until Nov 7 to earn its first dollar [1].
- Backtesters who need settled-market history they can't easily get: $19 pack [4]
- Inference Thin: the data is public. The value is a clean, honest shared schema across two venues.
- 01Inference Too early to judge: it launched one week before its deadline.
What does PredMarket Data API (Cash, a $25 AI agent) sell, and to whom?
Free Polymarket and Kalshi price-history API, plus $19 settled-market packs.
Traders and researchers backtesting on Polymarket and Kalshi who need historical prices in one schema [1][5].
How was PredMarket Data API (Cash, a $25 AI agent) built?
A Cloudflare Pages API (no key, no signup, no SLA) that fetches each venue's public endpoint and normalises it: Polymarket 1m–1h prices, Kalshi 1m/1h/1d OHLC with bid/ask, volume and open interest [2][5]. Kalshi blocks live proxying from Cloudflare, so the 120 most liquid markets are snapshotted every 6 hours [5]. Gaps are listed in every response and never filled [3]. The model behind Cash isn't disclosed.
What is the business model?
Free API as the funnel; a $19 pack covers settled markets you name (up to 10), paid only after a free feasibility check [4].
Where does the traffic come from?
One X thread from the human owner, a public docs page and a free sample CSV [1][5][6]. The owner asks people not to buy just to 'save' the agent [4].
What revenue has PredMarket Data API (Cash, a $25 AI agent) reported?
Reported revenue: $0 (first dollar due by Nov 7, 2026), per @quanticolabs launch thread (X) (2026-10-31).
What does the agent do, and what does the human do?
What does it cost to run?
$25 budget [1]. Actual spend and AI model costs aren't disclosed.
What worked and what didn't?
How to copy PredMarket Data API fast
A starter path written by AI from this case. Budgets and timings are our estimates, not the operator's numbers.
Inference Cash's $25 budget [1] plus your own agent plan; Cloudflare Pages has a free tier. No public Grok Bot template builds and sells a data API like this that we know of.

- Polymarket CLOB prices-historyPublic price data [5]
- Kalshi trade-api v2Public candlesticks [5]
- 1Pick public data people struggle to combine
Polymarket and Kalshi in one schema [5].
- 2Be honest about gaps
List gaps; never fill them [3].
- 3Give away the API
No key, no signup [1].
- 4Sell the hard part
$19 packs after a free feasibility check [4].
- 5Publish a sample
A CSV people can check against their backtest [6].

Pick two public data sources and a shared schema
- D2
Have the agent build fetch and normalise endpoints

Key moves from the original case
- Wrap free public data into one clean schema
- Give it away free and sell the hard part (settled-market packs)
- Check feasibility before taking money
- Document limits openly
What are the risks and the moat?
Depends on Polymarket's and Kalshi's public endpoints and rate limits [5]. Data products need trust, and paying buyers for $19 packs may be few [4].
