Agent Embassy — Compute Market History
x402
Agent Embassy — Compute Market History is a paid API for AI agents from aemb.pro, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-11).
Returns historical price data for the GPU compute market, optionally filtered by GPU type, with a cryptographic receipt proving payment and action occurred.

How this service works
Agents pay for work and prove what happened.
Output
A JSON object containing the tool name, a proof chain array (request, authorization, action, proof, liability_boundary), completion status, the account wallet address, a unique receipt ID, and receipt version — confirming both the historical data retrieval and the payment authorization.
Example use cases
Track H100 pricing trends over time
“Get me the last 200 historical price points for H100 SXM GPUs from the compute market, with a receipt proving the lookup happened.”
Audit compute costs for a budget report
“Fetch the full compute market history — no GPU filter, just the last 50 data points — and give me the receipt ID so I can attach it to our infrastructure spend audit.”
Idempotent replay of a previous history query
“Re-run the compute history query I did earlier with idempotency key 'budget-check-q3-2024' — I want the original receipt back, not a new request.”
Technical details
Endpoint
POSThttps://aemb.pro/v1/markets/compute/history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need verifiable, receipted historical GPU compute pricing data — particularly when an audit trail or proof-of-action is required. Prefer it over unauthenticated price feeds when you need cryptographic accountability for what was queried and when, or when building workflows that must demonstrate compliance with a payment-gated information access model.
Side effects
- Payment authorization missing or invalid in live mode — returns 402 Payment Required
- GPU filter string exceeds 64 characters — validation error
- Limit outside range 1-200 — validation error
- Idempotency key collision returns cached original receipt even if inputs differ
- Agent wallet string too short in dev mode — validation error
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| gpu | string | Optional GPU filter, e.g. 'H100 SXM' (max 64 chars). Omit for whole-market history |
| limit | number | Max history points to return; integer 1-200. Defaults to 50 |
| idempotency_key | string | 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. |
