# Daily fixings for a ticker over a date range.

`GET /v1/index/history`

## Request

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

Quote segments start 2026-09-13. SPOT tickers reach back to the start of the spot series (AWS daily from 2022-05-31 for A100, V100, T4, A10; from 2023-07 for H100), each row carrying its data source.

## Query parameters

- `ticker` string, required
- `from` string, date
- `to` string, date

## Response `200`

Series.

- FixingSeries
  - `ticker` string
  - `gpu` string
  - `segment` string
  - `methodology` string
  - `unit` string
  - `count` integer
  - `series` object[]
    - `day` string, date
    - `value` number
    - `lo` number, nullable
    - `hi` number, nullable
    - `n` integer
    - `source` string
    - `instance` string

## 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.
