A sample Stock API pricing simulation for downloading multi-year daily OHLCV history across many IEX symbols.
Use Case: Historical OHLCV Backfill for Many Symbols
This example estimates the cost of downloading multi-year daily OHLCV history for a large symbol universe.
Assumptions
| Item | Value |
|---|---|
| Product | Stock API |
| Workflow | Historical OHLCV backfill |
| Endpoint pattern | GET /v1/ohlcv/exchange-symbol/{exchange_id}/{symbol}/history |
| Exchange | IEXG |
| Example symbols | AAPL, MSFT, NVDA, TSLA, AMZN |
| Period | 1DAY |
| Time range | 2020-10-01 to 2026-05-01 |
| Symbols | 11,000 |
| Sample response size per symbol | 112.23 KB |
| Estimated transferred data | ~1.18 GB |
Example request:
| Symbol | Example endpoint |
|---|---|
| AAPL | GET /v1/ohlcv/exchange-symbol/IEXG/AAPL/history?period_id=1DAY&time_start=2020-10-01&time_end=2026-05-01&limit=10000 |
| MSFT | GET /v1/ohlcv/exchange-symbol/IEXG/MSFT/history?period_id=1DAY&time_start=2020-10-01&time_end=2026-05-01&limit=10000 |
| NVDA | GET /v1/ohlcv/exchange-symbol/IEXG/NVDA/history?period_id=1DAY&time_start=2020-10-01&time_end=2026-05-01&limit=10000 |
Estimated usage
Sample response size:
112.23 KB per symbol
For 11,000 symbols:
112.23 KB × 11,000 = ~1.18 GB
Pay As You Go estimate
Since this is below 32 GB/day, the first daily tier applies:
1.18 GB × $1.00/GB = $1.18
Plan comparison
| Plan | Price per Credit | Monthly cost | Included credits | Estimated cost |
|---|---|---|---|---|
| Pay As You Go | $1.00/Credit | No commitment | N/A | $1.18 |
| Committed 64 | $0.85/Credit | $64 | ~75.29 credits | $64.00 |
| Committed 256 | $0.75/Credit | $256 | ~341.33 credits | $256.00 |
| Committed 512 | $0.70/Credit | $512 | ~731.43 credits | $512.00 |
| Committed 1024 | $0.65/Credit | $1,024 | ~1,575.38 credits | $1,024.00 |
Result
For this one-time OHLCV backfill sample, Pay As You Go is the lowest-cost option.
Committed plans are better suited when this workflow is combined with larger recurring data downloads, such as Level 2, Level 3, trades, or quotes.
Caveat
Actual transferred data depends on the number of symbols, selected date range, response size, compression, retries, and whether the workflow downloads additional endpoints or metadata.
