| Valuation market | GET /v1/ohlcv/POLYMARKET/WILL-THE-AVERAGE-MONTHLY-ETHEREUM-GAS-PRICE-HIT-20-GWEI-BEFORE-2027_NO/history?period_id=1MIN&time_start=2026-01-01T00:00:00Z&time_end=2026-06-30T23:59:59Z&limit=1000 |
Estimated usage
Records per market:
180 days × 1,440 minutes/day = 259,200 records
With a page size of 1,000 records:
259,200 ÷ 1,000 = 259.2, rounded up to 260 calls per market
For 250 markets:
260 calls × 250 markets = 65,000 calls
Pay As You Go estimate
API call pricing is tiered daily:
| Tier | Usage | Cost |
|---|---|---|
| First 1,000 requests/day | 1,000 | $5.00 |
| More than 1,000 requests/day | 64,000 | $64.00 |
| Total | 65,000 | $69.00 |
Plan comparison
| Plan | Price per Credit | Monthly cost | Included credits | Estimated cost |
|---|---|---|---|---|
| Pay As You Go | $1.00/Credit | No commitment | N/A | $69.00 |
| 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 historical backfill sample, Committed 64 has the lowest estimated cost.
Pay As You Go is close in cost and may still be simpler if the customer does not expect recurring usage. Larger committed plans are better suited when this backfill is combined with ongoing monitoring, larger market coverage, or repeated historical jobs.
Caveat
Actual usage depends on pagination, endpoint limits, selected period, number of markets, available history, retries, and whether the customer downloads additional market activity or order book history.
