Agent Embassy — Compute Spot Market Data
x402
Agent Embassy — Compute Spot Market Data is a paid API for AI agents from agent-embassy.fly.dev, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-12).
Returns real-time spot price quotes for GPU compute resources (H100 SXM, RTX 4090, etc.) from the paid compute market, priced in USDC via x402.

How this service works
Agents pay for work and prove what happened.
Output
A JSON object containing: the cheapest current ask prices in USD per GPU hour for available GPU types (e.g. H100 SXM at $1.79/hr, RTX 4090 at $0.14/hr), the timestamp when prices were observed, and a note clarifying that prices are ephemeral asks rather than guaranteed delivery costs.
Example use cases
Budget GPU compute for AI training run
“What's the cheapest H100 SXM spot price available right now? I need to estimate how much a 10-hour training run will cost before I kick it off.”
Compare GPU tiers before provisioning
“Pull the current spot market prices for H100 SXM and RTX 4090 so I can decide which GPU tier makes sense for my workload today.”
Monitor GPU market for cost optimization
“Check the current compute spot market prices and tell me if H100 SXM rates have dropped below $2 per hour yet.”
Technical details
Endpoint
GEThttps://agent-embassy.fly.dev/v1/markets/compute/spot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time GPU spot market pricing to inform compute budgeting, provider selection, or cost optimization decisions. It is purpose-built for AI agents operating in agentic commerce contexts where machine-verifiable, USDC-paid data access is required. Prefer it over scraping cloud provider pricing pages when you need structured, programmatic price data with a clear cost-per-call model on Base or Arbitrum One.
Side effects
- Payment failure: x402 USDC payment of $0.25 not accepted or wallet has insufficient funds
- Market data unavailable: no current spot asks available for one or more GPU types
- Stale data: observed_at timestamp may lag real market conditions
- Rate limiting: excessive polling may trigger throttling
- Network error: fly.dev host unreachable or returning 5xx
