Compute History

compute_history

Idempotent

Use compute_history when you need GPU compute market history: a bounded time series of per-GPU cheapest/median/offer counts — or whole-market history when no GPU is named — sealed into your signed receipt. Prices are ephemeral asks, never delivered-cost guarantees. POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header. See https://docs.cdp.coinbase.com/x402 Paid tool — $0.25, USDC on Base or Arbitrum One. Paid URL: https://aemb.pro/v1/markets/compute/history.

Input Schema

TableJSON Schema

Name	Required	Description
`gpu`	No	Optional GPU filter, e.g. 'H100 SXM' (max 64 chars). Omit for whole-market history
`limit`	No	Max history points to return; integer 1-200. Defaults to 50
`idempotency_key`	Yes	Idempotency key: UUID v4, client-generated, one per logical request. Replaying the same key on this tool returns the original receipt — the action is not re-run, and the first request's receipt wins even if you resend different inputs. Published example keys are rejected. Keys are scoped per tool and per payer account: a key never returns another wallet's receipt.

Output Schema

TableJSON Schema

Name	Required	Description
`how`	Yes	How to pay: POST the tool inputs as JSON to paid_url with an x402 v2 PAYMENT-SIGNATURE header
`tool`	Yes	Tool name, e.g. ping
`asset`	Yes	Settlement asset
`price`	Yes	Exact price, e.g. "$0.05"
`networks`	Yes	EVM CAIP-2 network ids accepted
`paid_url`	Yes	x402-paid HTTPS URL to POST the tool inputs to
`facilitator`	Yes	x402 facilitator
`payment_required`	Yes	Always true: this MCP tool is a payment pointer; the tool itself is monetized via x402.
