Estimate Image Vectorization API Costs Before Launch

When you estimate PerfectVector API costs, budget for the successful conversions you expect to finish. Then work out what you need to buy to cover them. Those are different numbers when credits come in packs. A 75-conversion launch might need 100 purchased credits, leaving 25 available for later work.

Count successful conversions before pricing the packs

For PerfectVector, one successful live conversion uses one API credit under current v1 pricing. Test-mode calls, rejected requests and failed conversions use none. If your app stops waiting and the conversion later succeeds, it still uses a credit. PerfectVector API credits

Say you forecast 300 live submissions, of which 250 will succeed. Budget 250 credits for those results. Reconcile actual usage from each conversion's final credits_charged value. An initial 202 Accepted response can show zero credits charged while a conversion is still running. If the same submission appears twice in your logs, count the unique conversion once.

If the API accepted the original upload, retry within 24 hours using the same idempotency key, account, key mode (test or live), image bytes, and processing options. The API returns the original conversion in its current state without a second charge. Within that window, reusing the key in the same account and mode with different bytes or options returns 409 idempotency_conflict. PerfectVector safe retries

Compare the cash cost for your launch volume

These examples start from a zero API balance and use PerfectVector's listed beta checkout prices in USD before any applicable taxes. At these prices, the 10-, 100- and 1,000-credit packs cost $4, $16 and $80. The unit price shown on a pack assumes you use every credit. PerfectVector API pricing

Cash per expected successful SVG is checkout spend divided by expected successes, rounded to cents. It answers how much cash you put down for this run. Leftover credits may cover future work, so this figure can fall as you use them. For 250 successes, two 100-credit packs plus five 10-credit packs would give you exactly 250 credits for $52. Three 100-credit packs cost $48 and leave 50 credits.

Plan for a quiet month and a spike

Suppose 75 conversions are committed for launch and another 175 might arrive the next month. One 100-credit pack covers the launch for $16. If all 175 arrive, the 25 remaining credits leave a 150-credit shortfall. Two more 100-credit packs cost $32 and leave 50 credits after the spike. Buying three packs up front would cost the same $48, but it brings that extra spend forward even if the second batch never comes.

Start with the available credits in your API account and check how many will still be valid when the next batch runs. Purchased API credits expire 12 months after purchase. PerfectVector uses purchased credits with the earliest expiration first, after any granted credits. PerfectVector API credits

For your own estimate, record four numbers for each expected batch.

1. Expected successful live conversions.
2. Available API credits that you can use when that batch runs.
3. The cost of the least expensive eligible pack mix that covers the shortfall.
4. Credits left afterward and their expiration dates.

Check the high-volume case before paying. A lower listed price per credit can still require a bigger initial purchase, and unused credits only help if you can spend them before expiry.

FAQ

Do polling and SVG downloads use another credit?

No. PerfectVector charges a credit when a live conversion succeeds. Checking status or downloading an available result again does not use another credit. PerfectVector API credits

Can I apply website credits to API requests?

PerfectVector keeps API and website credit balances separate. Website plans do not include API credits. PerfectVector API pricing

Can I test the API before buying a pack?

Yes. Use a test key and an eligible sample image. It returns a fixed sample SVG without spending credits. Use a live conversion when you need to inspect the trace of your specific image. PerfectVector test mode
