Using a third party API
Recommended if EndCaptcha is not included in your software

EndCaptcha supports the API specs defined to work with DeathByCaptcha, Decaptcher, and Antigate. To start using EndCaptcha on a software that supports these services, you may download EndCaptcha's API Tunneler or make some minor configuration changes to your host file (requires manipulation of system files).

Download API Tunneler or Hosts file configuration details

Using DBC API clients

EndCaptcha supports deathbycaptcha clients, just reconfigure your client scripts with your EndCaptcha credentials and our API url (dbc.endcaptcha.com).

For better results we recommend a captcha polling time of 3 seconds. Using less than 1 second is considered abusive and may get you banned.

Integrating EndCaptcha's official API
Recommended for faster solving times

EndCaptcha utilizes advanced polling methods that support overall faster perceived solving times. It is highly recommended to include EndCaptcha's API into your software as opposed to using one of the supported Third Party APIs.

All accounts created in EndCaptcha remain as sole property of EndCaptcha, and its parent company. Sharing account details, selling and reselling accounts, and selling awarded coupons is prohibited. Violation of this policy will result in account suspension.

Service Level Agreement:

Even though customers may submit Unsupported Images, and EndCaptcha will do it’s best effort to solve said images in a timely fashion, the Service Level Agreement won't cover any Unsupported Images and won't be available during dates included in the Maintenance and Holidays Calendar. EndCaptcha reserves the right to include Unsupported Images at any time without previous notice.

Additional information about the types of insurances provided in the Service Level Agreement may be found here.

Refunds and Chargebacks:

Any fulfilled claims for chargebacks before consulting our helpdesk will result in an immediate suspension of the clients account and appropriate legal action (fraud).

Refunds are processed in a case-by-case basis. We will not award refunds if:
- The client is unsatisfied with the results obtained when submitting Unsupported Images.
- The client has partially used the service and has no use for remaining balance in the client's account.
- The client was unaware of any explicitly written service constraints before making a purchase.

If a refund is awarded, the client will receive funds equivalent to the remaining credit balance in the client's account.

Maintenance and Holidays Calendar

Maintenance and Holidays Calendar

Although we will try our best to keep maintenance and undercapacity occurrences to a minimum, there will be rare occasions in which these events will be unavoidable, and thus not covered by the Insurances of our Service Level Agreement. The Maintenance and Holidays Calendar will show the foreseeable events of diminished Quality of Service.

Event Description Date Duration

Service Level Agreement

Service Level Agreement

EndCaptcha offers a unique Service Level Agreement that compensates its users when there is a drop in Quality Standards.

About Compensation

Users will be compensated with Compensatory Credits, which will be deposited once the currently used Credit Package has been consumed. The amount of Compensatory Credits will be calculated depending on the type of Insurance and the Compensation Coverage Level of the currently used package.

Compensatory Credits, Promotional Credits, and Free Credits won't be subject to the terms of the Service Level Agreement and its insurances.

Compensation Coverage Level

The user will be given a Slowness Insurance and an Outage Insurance. These types of insurances will provide compensation to users whenever certain Quality Standards are not met. There will be different Compensation Coverage Levels depending on what Credit Package was bought. The amount of Compensatory Credits will be the result of multiplying the Compensation Coverage Level percentage with the amount of quantifiable times the Quality Standards are not met.

Slowness Insurance

*Approximately 70% of all images are decoded with-in 7-8 seconds on average. The remainder is also guaranteed to be decoded with-in 11 seconds max. For any images that take longer than 11 seconds to solve, our slowness insurance policies kick in.

The Slowness Insurance will provide compensation to EndCaptcha users for images that are getting typed in more than 11 seconds. The compensation will be calculated on an Image-by-image basis.

Example Case:
Compensation Level: 60% Coverage
Images over 11 seconds: 2,000
Compensation Credits: 1,200

The Slowness Insurance won't cover Unsupported Images, and is not applicable during the time ranges included in the Maintenance and Holidays Calendar.

Outage Insurance

The Outage Insurance will provide compensation to EndCaptcha users when the service suffers from an unexpected outage that renders the service partially or completely unresponsive. The Outage Insurance will only cover cases of registered server problems on EndCaptcha's side, it will not cover issues in the user's side or connectivity problems between the user and EndCaptcha.

The Outage Insurance will only compensate credits in accordance with the usual activity of the users during the event. The usual activity of the user will be determined by the average past submissions made by the user during the weekday and time of the outage event.

Example Case:
Compensation Level: 100% Coverage
Usual Activity During Event: 2,000 Images
Compensation Credits: 2,000 Images

The Outage Insurance will be evaluated on a case by case basis whenever the user opens an outage claim at outage@endcaptcha.com. For outage claims to be valid, they have to be opened with-in 72 hours of the outage occurring.

The Outage Insurance is not applicable during the Maintenance time ranges included in the Maintenance and Holidays Calendar, which have been announced a minimum of 12 hours in advance. The Outage Insurance is not applicable when deliberate attacks to our service are made.

EndCaptcha reserves the right to change its Service Level Agreement without prior notice.
