What is a credit?
A credit is the unit of consumption for every API call. Each endpoint has a fixed credit cost based on the lookups performed. A failed validation still costs the same as a successful one — the lookup was performed regardless.
Credit costs per endpoint
| Endpoint | Credits |
|---|
POST /v1/email | 1 |
POST /v1/ip | 1 |
POST /v1/phone | 2 |
POST /v1/domain | 2 |
POST /v1/deliverability | up to 3 |
POST /v1/contact-intel | up to 4 |
POST /v1/fraud-signals | up to 4 |
Bundle endpoints — dynamic billing
Bundle endpoints are priced dynamically based on which optional fields you include. You are only charged for the sub-lookups actually performed.
/v1/deliverability
| Fields provided | Credits charged |
|---|
email only | 1 |
email + phone | 3 |
email costs 1 credit.
| Fields provided | Credits charged |
|---|
email only | 1 |
email + ip | 2 |
email + phone | 3 |
email + domain | 3 |
All fields (email + phone + domain + ip) | 4 |
/v1/fraud-signals
| Fields provided | Credits charged |
|---|
email only | 1 |
email + ip | 2 |
email + phone | 3 |
All fields (email + phone + ip) | 4 |
Only pass the fields you need. Bundle endpoints bill for the lookups you actually request — omitting optional fields reduces the credit cost proportionally.
Monthly allowance
Credits are allocated at the start of each billing cycle and reset monthly. They do not roll over.
| Plan | Credits / month |
|---|
| Free | 200 |
| Starter | 5,000 |
| Pro | 25,000 |
Checking your balance
Your remaining credit balance is visible in the dashboard. Each API response also includes a credits_used field showing the cost of that specific call.
Running out of credits
When your credit balance reaches zero, subsequent API calls return a 402 Payment Required response. You can:
- Upgrade your plan — for a higher monthly allowance
- Purchase a credit add-on pack — one-off top-up that doesn’t affect your billing cycle
| Add-on pack | Credits | Price |
|---|
| Starter pack | 1,000 credits | $25 |
| Growth pack | 5,000 credits | $100 |
| Scale pack | 20,000 credits | $350 |
