Use Case: Current Order Book Liquidity Monitoring
A sample Prediction Markets API pricing simulation for polling current order books across selected Polymarket markets.
Use Case: Current Order Book Liquidity Monitoring
This example estimates the cost of polling current order books for a focused set of active prediction markets.
Assumptions
| Item | Value |
|---|---|
| Protocol | REST |
| Endpoint pattern | GET /v1/orderbook/{exchange_id}/{market_id}/current |
| Exchange | POLYMARKET |
| Markets monitored | 20 markets |
| Polling frequency | Every 5 minutes |
| Polling cycles per day | 288 |
| Estimated usage | 5,760 calls/day |
Example endpoints:
| Market | Example endpoint |
|---|---|
| Bitcoin Yes market | GET /v1/orderbook/POLYMARKET/BITCOIN-ABOVE-58K-ON-JUNE-5-2026_YES/current |
| Bitcoin No market | GET /v1/orderbook/POLYMARKET/BITCOIN-ABOVE-58K-ON-JUNE-5-2026_NO/current |
| MLB Over market | GET /v1/orderbook/POLYMARKET/2026-MLB-WIN-TOTALS-BOSTON-RED-SOX_O-85-5/current |
| MLB Under market | GET /v1/orderbook/POLYMARKET/2026-MLB-WIN-TOTALS-BOSTON-RED-SOX_U-85-5/current |
Estimated usage
20 markets × 288 polling cycles = 5,760 calls/day
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 | 4,760 | $4.76 |
| Total/day | 5,760 | $9.76 |
Estimated 30-day usage:
$9.76 × 30 = $292.80/month
Plan comparison
| Plan | Price per Credit | Monthly cost | Included credits | Estimated monthly cost |
|---|---|---|---|---|
| Pay As You Go | $1.00/Credit | No commitment | N/A | $292.80 |
| Committed 64 | $0.85/Credit | $64 | ~75.29 credits | $281.51 |
| 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 sample, Committed 256 has the lowest estimated cost because the estimated monthly usage is covered within the included credits.
Pay As You Go may still be simpler for short tests or occasional checks. Committed plans are better suited for customers who expect recurring monitoring across multiple markets.
Caveat
Actual usage depends on the number of markets, polling frequency, retries, and whether the integration also calls market discovery, activity, or historical endpoints.
