API pricing

This page provides detailed information about Autentique’s API pricing structure. It includes tables with the costs for different actions, along with usage and billing examples.

API usage follows the same plans as regular usage through the web application. However, the plan’s cost serves as a monthly usage commitment, and additional charges apply if total API usage exceeds that amount. The free plan has no fees but is limited to 20 documents per month.

You can check your current API usage on Plans and Payment section of your account.

Prices per document and signature request

Action	USD	BRL
Document creation	$ 0.01	R$ 0,06
Signature request via Email	$ 0.002	R$ 0,013
Signature request via Whatsapp	$ 0.02	R$ 0,12
Signature request via SMS	$ 0.03	R$ 0,16
Signature request via link, signed through email	$ 0.002	R$ 0,013
Signature request via link, signed through SMS	$ 0.03	R$ 0,16
Signature request via link, signed through Whatsapp	$ 0.02	R$ 0,30
Signature with additional Phone validation	$ 0.03	R$ 0,16

Prices are cumulative and depend on the number of signers and the signature methods used.

Example: A document created with 2 signers (one via email and one via WhatsApp):

• Create document: $ 0.01

• Signer 1: Signature request via email: $ 0.002

• Signer 2: Signature request via WhatsApp: $ 0.02

Total document API charge: $ 0.193

Signers added via a signing link can select their preferred signing method: email, SMS, WhatsApp, or authentication via Google, Microsoft, or Facebook. They are charged according to the method they choose to sign the document, but signatures completed via Google, Microsoft, or Facebook login are free of charge.

Example: A document created with 2 signers (both via signing link):

• Create document: $ 0.01

• Signer 1: Signs using Google login (Free)

• Signer 2: Signs via WhatsApp link ($ 0.02)

Total document API charge: $ 0.03

The cost of signing via a WhatsApp link may differ from the cost of sending a signature request through WhatsApp due to WhatsApp API message category pricing. However, this is not usually the case. Keep this in mind when designing your signing flow to optimize message delivery costs.

If you have a specific use case that’s not feasible under this pricing model, feel free to reach out to our sales team. Custom, volume-based pricing can be negotiated under the Corporate plan.

Pricing per query

Some queries incur a cost when executed. This charge is primarily intended to discourage implementations that make excessive data requests (we’ve all been there). Still, those workarounds started adding up on our end, so please don’t use Autentique as your backend.

Query	USD	BRL
Retrieve document data (per document)	$ 0,0002	R$ 0,001
Webhook Delivery	$ 0,00004	R$ 0,0002

“Retrieve document data” charges are applied per document retrieved, not per query. So if you request 10 documents in a single query, you’ll be charged $ 0.0002 × 10.

You typically don’t need to worry about query costs unless you’re doing something very wrong. If you ever notice a significant charge from queries, it might be a good time to sit in the shower, stare at the tiles, and reconsider your architecture choices.

Webhook pricing

To keep your application updated efficiently, you can set up webhook endpoints to receive real-time updates. This is the clean, no-hacks way to keep your systems in sync with the latest document information. Check out our documentation for details, and contact support if you have any questions.

All webhook deliveries incur processing costs and are therefore included in billing.

Failed webhook deliveries appear in your dashboard, where you can review and retry them. Failed deliveries are included in billing, but retries are not.

Deprecated webhook events are also counted but do not appear in the failed webhooks list.

Request limit

Each plan includes a default rate limit (requests per minute) per API token. If you need a higher limit, just reach out and we’ll adjust it based on your needs.

Plan	Standart limit
Free	10 per minute
Professional	60 per minute
Corporate	200 per minute

Usage commitment and billing

The plan’s cost represents a minimum monthly usage commitment. If your API usage exceeds that amount, the excess will be billed on an additional invoice covering the previous month’s activity.

Example: An organization on the Professional plan ($ 19.00/month) creates 1,000 documents via API with two email signers each:

• Document creation: $ 0.01 × 1,000 = $ 10.00

• Two email signers per document: $ 0,002 × 1,000 × 2 = $ 4.00

Total usage: $ 14.00 (below the plan's value)

Final charge: Plan cost only ($ 19.00).

Example: An organization on the Professional plan ($ 19.00/month) creates 1,000 documents via API with two WhatsApp signers each:

• Document creation: $ 0.01 × 1,000 = $ 10.00

• Two WhatsApp signers per document: $ 0.02 × 1,000 × 2 = $ 40.00

Total usage: $ 50.00 (above the plan amount)

Final charge: $ 19.00 (plan) + $ 31.00 (overage amount) = $ 50.00

---

Important: Actions performed through the web application don’t generate charges and don’t affect API billing.

You create 1,000 documents via API with two email signers ($ 14.00).

You also create 2,000 documents through the web app.

Total charge: Plan cost only ($ 19.00).

Sandbox and tests

Documents created with the parameter sandbox: true are not charged. However, they are meant strictly for testing and are automatically deleted after a few days.

Do not use real documents in sandbox. The sandbox is for testing purposes only. Sandbox documents are automatically deleted, they do not generate audit logs, and cannot be used for verifying signatures or authenticating documents.
