What is in the history
| Dataset | Endpoint | Since |
|---|---|---|
| Crate downloads, daily, 1,000 crates | /v1/history/crates/{name} | Jul 27, 2026, and growing every day |
| AI API prices, every model and change | /v1/history/llm | Oct 17, 2026 |
| GPU rental prices, 17 clouds | /v1/history/gpu | Oct 24, 2026, one snapshot a day |
| Uptime of 14 developer services | /v1/history/uptime | Oct 24, 2026, a check every 5 minutes |
New datasets record forward from the day we started them. The history only gets longer; your price does not change while you stay subscribed.
Questions
Can my agent pay per call instead?
Yes. Without a key, every history endpoint answers HTTP 402 with x402 terms: $0.01 a call ($0.10 for bulk), USDC on Base. Sign, retry, get the data. No account.
What counts as commercial use?
Showing or reselling the data inside a paid product, client reports or a dashboard you sell. Free and Pro keys cover your own analysis and internal tools, with credit to Tensorust.
How do I cancel?
From your key page, one button. The key works to the end of the month you paid for. No refunds for partial months.
