Take the data directly, no login, no key
All of Sinan's measurement results are static JSON files, generated in the same batch as the web pages; anyone can download them, crawl them, or drop them into their own scripts. This page explains what each file is, how often it updates, what the fields look like, and our stability commitments.
Stability promise
- Published fieldsNever deleted, renamed or redefined; fields are only ever added. Any change is announced on this page 30 days in advance, with old and new versions provided side by side.
- Every file has at the top
generated_at(Beijing time); the methodology version is recorded in Definitions。 - Files are served through Cloudflare's global cache with no crawl-rate limit; please include a User-Agent header we can reach you through.
- Data may be freely cited and republished with the credit "Data: Sinan Lab compute.sinanlab.com". No payment is accepted from any measured channel; outbound links carry no promo parameters.

Sinan Robo · open embodied models
| File | Updated | URL |
|---|---|---|
| robo.sinanlab.com/data/models.json Robo model index: each open-source embodied model's license, parameter count, weight and code locations, input modalities, target embodiment, and the evidence source for every field. | each release | https://robo.sinanlab.com/data/models.json |
| robo.sinanlab.com/data/compat.json Model × embodiment compatibility matrix, with a status for each cell (official / community-verified / theoretically feasible / unsupported / unknown) and evidence. | each release | https://robo.sinanlab.com/data/compat.json |
| robo.sinanlab.com/data/embodiments.json Embodiment (robot) index: degrees of freedom, end effector, SDK, price range, data format. | each release | https://robo.sinanlab.com/data/embodiments.json |
| robo.sinanlab.com/data/hardware.json Inference hardware and rental reference prices. | each release | https://robo.sinanlab.com/data/hardware.json |
Shared field conventions for both sites: all prices are numbers (USD, or marked cny); all evidence is {url, fetched, source_type, note}; unverified fields are null, never filled in with default values.
Ready-made tools
| sinan-probe Test a relay site from your terminal with your own Key: consistency probe, TTFB, echoed model name. Single file, Python standard library only. | github.com/sinanlabs/compute/cli |
| GitHub Action · price watch Copy one workflow file into your repository, change one line listing the models, and it checks those models' market median price on the relay market every day, opening an Issue when the change exceeds the threshold. | templates/github-action |
| Badge The price index badge refreshes automatically every day; ranked sites and verified sites each have their own badge, with embed code available on the site page. | /badge/price-index.svg |
Read the price index in three lines of Python:
import json, urllib.request
pi = json.load(urllib.request.urlopen(urllib.request.Request("https://compute.sinanlab.com/price-index.json", headers={"User-Agent": "you@example.com"})))
print(pi["latest"])

Do you want Sinan to route your calls for you?
The idea: you hold your own Keys for each site; Sinan only measures, filters by your criteria, routes requests to the channel you chose, and logs latency and cost. Right now weNot doneVotes decide whether this gets built.
