# Every raw spot price-change event of a region for one UTC day, as a gzip TSV file.

`GET /v1/spot/export/events`

## Request

- Base URL: `https://cloud.trycorpus.ai`
- URL: `https://cloud.trycorpus.ai/v1/spot/export/events`
- Auth: one of:
  - API key in header `PAYMENT-SIGNATURE`
  - API key in header `Authorization`
  - API key in header `X-Api-Key`

Columns: ts (ISO 8601), az, instance, product, price. The exact file the store ingests: every type and zone, repeats included. About 25,000 rows / 170 KB for a large AWS region-day. Use /catalog for the covered window.

## Query parameters

- `provider` 'aws' | 'gcp' | 'azure', required
- `region` string, required
- `date` string, date, required

## Response `200`

The gzip file (tab-separated).

## Other responses

- `400`: Invalid or missing parameter.
- `402`: Payment required. The x402 v2 payment requirements are in the PAYMENT-REQUIRED header (base64 JSON) and repeated as the JSON body: `accepts[]` lists every offer (USDC on 13 networks: eip155:8453, eip155:143, eip155:1, eip155:43114, eip155:42161, eip155:10, eip155:137, eip155:130, eip155:146, eip155:480, eip155:1329, eip155:999, eip155:5042) with amount and payTo address. Circle Gateway offers cover every listed network; a Coinbase-facilitated offer covers Base. The same response carries an MPP challenge (WWW-Authenticate: Payment, USDC on Tempo). Retry with a PAYMENT-SIGNATURE header or an MPP credential, or let an x402 or MPP client (for example `circle services pay` or `mppx`) handle it; a prepaid key in X-Api-Key is charged instead of a 402.
- `404`: Unknown provider, region or instance type.
- `503`: The store is still warming up after a restart; retry in a minute. No payment is taken.
