“Can you check what AI models the Gambit GPU shop currently has available? I want to know all my options before picking one to run inference on.”
Compare Gambit offerings before purchase
“Before I commit to using the Gambit GPU shop, can you pull up their full model catalog so I can see if they have Qwen or Nemotron available?”

Technical details
Endpoint
POSThttps://spark-2f53.tail8a7863.ts.net/gambit/x402/modelsWhen to prefer
Use this endpoint when you need to programmatically discover which AI models and services the Gambit GPU shop currently offers before making a more expensive inference call. It is the cheapest possible probe ($0.01 USDC) to confirm availability. Prefer this over guessing model names or hardcoding them, especially if the catalog may change. Choose this over the handwritten-letter or other inference endpoints when you only need metadata, not actual model output.
Side effects
- Payment header missing or invalid – 402 Payment Required response
- Insufficient USDC balance on Base network – payment fails
- Tailscale network unreachable – connection timeout or DNS failure
- Endpoint returns non-200 if x402 payment handshake fails
- ok: false in response body if backend service is down
