Amazon API Gateway pricing
With Amazon API Gateway, you only pay when your APIs are in use. There are no minimum fees or upfront commitments. For HTTP APIs and REST APIs, you pay only for the API calls you receive and the amount of data transferred out. There are no data transfer out charges for Private APIs.
Starting July 15, 2025, new AWS customers will receive up to $200 in AWS Free Tier credits, which can be applied towards eligible AWS services, including Amazon API Gateway. At account sign-up, you can choose between a free plan and a paid plan. The free plan will be available for 6 months after account creation. If you upgrade to a paid plan, any remaining Free Tier credit balance will automatically apply to your AWS bills. All Free Tier credits must be used within 12 months of your account creation date. To learn more about the AWS Free Tier program, refer to AWS Free Tier website and AWS Free Tier documentation.
Free Tier
The Amazon API Gateway free tier includes one million API calls received for REST APIs, one million API calls received for HTTP APIs, and one million messages and 750,000 connection minutes for WebSocket APIs per month for up to 12 months. If you exceed this number of calls per month, you will be charged the API Gateway usage rates.

1M REST API CALLS RECEIVED | 1M HTTP API CALLS RECEIVED | 1M MESSAGES | 750,000 CONNECTION MINUTES
per month
These free tier offers are only available to new AWS customers, and are available for 12 months following your AWS sign-up date. When your 12 month free usage term expires or if your application use exceeds the tiers, you simply pay standard, pay-as-you-go service rates.
HTTP APIs
Pay only for the API calls you receive and the amount of data transferred out.
REST APIs
Pay only for the API calls you receive and the amount of data transferred out. There are no data transfer out charges for Private APIs. However, AWS PrivateLink charges apply when using Private APIs in API Gateway. API Gateway also provides optional data caching charged at an hourly rate that varies based on the cache size you select.
WebSocket APIs
Pay only for messages sent and received and the total number of connection minutes. You may send and receive messages up to 128 kilobytes (KB) in size. Messages are metered in 32 KB increments. So, a 33 KB message is metered as two messages.
API Gateway Portals
Pay only for PortalProducts associated to your Portals. Each Portal's monthly charge includes 10 PortalProducts with 40 ProductRestEndpoints each. Additional PortalProducts are billed separately. Monthly charges for both Portals and PortalProducts are prorated based on usage within that month.
Additional Charges
You may incur additional charges if you use API Gateway in conjunction with other AWS services or transfer data out of AWS. For details on AWS service pricing, see the pricing section of the relevant AWS service detail pages. Links to pricing for some of the commonly used services are listed below.
If you use external data transfers, you will be charged at the EC2 data transfer rate
Includes pricing for each hour that your VPC endpoint is provisioned in each Availability Zone
Includes pricing for requests and duration
Includes pricing for metrics and dashboards
Pricing Examples
HTTP APIs
Pricing Example 1: An API is used in a Serverless Web Application that invokes Lambda to return dynamic webpage content. The site gets 10,000 page loads per minute. Each API request is 12KB and the response is 46 KB.
10,000 page loads/minute * 60 minutes/hour * 24 hours/day * 30 days/month / 1,000,000 = 432 million requests per month.
300 million * $1.00/million = $300
132 million * $0.90/million = $118.8
Total = $418.8 ($0.97 per million)
Pricing Example 2: An API is used for uploading data into your HTTPS backend. The API is called 25 times per minute to upload documents. Each document is, on average, 4.5 MB in size.
25 call/minute * 60 minutes/hour * 24 hours/day * 30 days/month * 4.5 MB/512 KB/request = 9,720,000 requests per month * $1/million = $9.72
Total = $9.72
REST APIs
Edge Optimized and Regional APIs
An Edge Optimized or Regional API receives five million API calls per month, with each API call returning responses of 3 kilobytes (KB) in size with no caching.
Example below reflects pricing for US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Mumbai)
Amazon API Gateway API call charges = 5 million * $3.50/million = $17.50
Total size of data transfers = 3 KB * 5 million = 15 million/KB = 14.3 GB
Amazon API Gateway data transfer charges = 14.3 GB * $0.09 = $1.29
Total Amazon API Gateway charges = $17.50 + $1.29 = $18.79
Edge Optimized and Regional APIs
An Edge Optimized or Regional API receives 15 billion API calls per month, with each API call returning responses of 4 kilobytes (KB) in size with no caching.
Example below reflects pricing for US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Mumbai)
Amazon API Gateway API call charges = 333 million * $3.50/million = $1,165.50
667 million * $2.80/million = $1,867.60
14 billion * $2.38/million = $33,320.00
Total Amazon API call charges = $1,165.50 + $1,867.60 + $33,320.00 = $36,353.10
Total size of data transfers = 4 KB * 15 billion = 57,220.46 GB
Amazon API Gateway data transfer charges = 57,220.46 GB * $0.09 = $5,149.84
Total Amazon API Gateway charges = $36,353.10 + $5,149.84 = $41,502.94
Private APIs
A Private API receives five million API calls, with each API call having a request size of 0.3 kilobytes (KB) and returning responses of 3 kilobytes (KB). A VPC endpoint is provisioned in 1 Availability Zone (AZ) for the whole month (720 hours).
Example below reflects pricing for US East, US West (Oregon)
Amazon API Gateway API call charges = 5 million * $3.50/million = $17.50
Total Amazon API Gateway charges = $17.50
Total size of data transfers (Request + Response) = (3 KB + 0.3 KB) * 5 million = 16.5 million/KB = 15.7 GB
VPC Endpoint charges = 720 hours * $0.01/AZ/hr = $7.20
VPC Endpoint data processing charges = 15.7 GB * $0.01/GB = $0.16
Total Amazon VPC (AWS PrivateLink) charges = $7.20 + $0.16 = $7.36
Total charges = $17.50 + $7.36 = $24.86
Response Streaming Enabled REST APIs
Pricing Example 1: A customer uses Response Streaming for REST APIs for a real-time chatbot that streams responses as they're generated. Each response is 5KB and the API receives 1 million requests per month.
5KB response payload per request
5KB per request / 10MB request increment = 0.00049 request(s)
RoundUp (0.00049) = minimum of 1 billable request(s) applied
1,000,000 requests per month x 1 billable request(s) = 1,000,000 total billable request(s)
Amazon API Gateway API call charges: 1,000,000 requests x $3.50 per million requests= $3.50
Total size of data transfers: 1,000,000 requests * 5KB response payload = 4.77 GB
Amazon API Gateway data transfer charges = 4.77 GB * $0.09 per GB = $0.43
Total Amazon API Gateway charges = $3.50 + $0.43 = $3.93
The customer benefits from streaming responses with no additional cost beyond standard request and data transfer charges.
Pricing Example 2: A media service uses Response Streaming to deliver video files. The service receives 1,000,000 requests per month, with each response being 65MB.
65MB response payload per request
65MB per request / 10MB request increment = 6.5 request(s)
RoundUp (6.5) = 7 billable request(s)
1,000,000 requests per month x 7 billable request(s) = 7,000,000 total billable request(s)
Amazon API Gateway API call charges: 7,000,000 requests x $3.50 per million requests = $24.50
Total size of data transfers: 1,000,000 requests * 65MB response payload = 63,477 GB
Amazon API Gateway data transfer charges = 63,477 GB × $0.09 = $5,712.93
Total Amazon API Gateway charges = $24.50 + $5,712.93 = $5737.43
Pricing Example with Caching Required (US East, US West, EU (Ireland))
If your API needs 1.5 GB of cache for its data, you can provision a 1.6 GB cache at $0.038/hr.
$0.038 * 24 = $0.912/day
WebSocket APIs
Chat Application: 1000 users are connected to the chat application for 12 hours in a day. Each user sends 100 messages and receives 500 messages per day. Each message size is 3KB.
Example below reflects pricing in US East (N. Virginia)
Messaging Cost
Total messages per month = (100 (sent msgs) + 500 (received msgs)) * 1000 (users) * 30 (days) = 18M
Total messaging cost = 18,000,000/1,000,000 * $1.00 (per million) = $18
Connectivity Cost
Total connection minutes per month = 1000 (users) * 12 (hrs) * 60 (mins) * 30 (days) = 21,600,000
Total connectivity cost = 21,600,000/1,000,000 * 0.25 (cost per million) = $5.40
Total Cost = $18 (Messaging cost) + $5.40 (Connectivity cost) = $23.40
API Gateway Portals
Pay only for PortalProducts associated to your Portals. Each Portal's monthly charge includes 10 PortalProducts with 40 ProductRestEndpoints each. Additional PortalProducts are billed separately. Monthly charges for both Portals and PortalProducts are prorated based on usage within that month.
Pricing Example 1:
A Portal is created with 10 PortalProducts that are associated with it for a full month (730 hours). Each PortalProduct contains 20 ProductRestEndpoints, giving the Portal a total of 10 PortalProducts and 200 ProductRestEndpoints.
The first 10 PortalProducts, each with up to 40 ProductRestEndpoints, are included in the monthly Portal charge of $125.
Portals charges: $125
Additional PortalProduct charges: $0
Total APIGateway-Portals charge: $125 for the month (730 hours).
Pricing Example 2:
A Portal is created with 30 PortalProducts associated with it for 10 days. Each PortalProduct contains 40 ProductRestEndpoints, giving the Portal a total of 30 PortalProducts and 1,200 ProductRestEndpoints.
The first 10 PortalProducts, each with up to 40 ProductRestEndpoints, are included in the monthly Portal charge of $125. Each additional PortalProduct is charged at $12.50 per month.
Portals charges: 10 days/month * $125 = 243/730 hours * $125 = $41.66
Additional PortalProduct charges: 20 Additional PortalProduct charges: 10 days/month * 20 PortalProducts * $12.5 = 243/730 hours * 20 * $12.50 = $83.22
Total APIGateway-Portals charge: $41.66 + $83.22 = $124.88 for the 10 days
Pricing Example 3:
Two Portals, Portal1 and Portal2, are created with 25 PortalProducts total. Portal1 is associated with 10 PortalProducts, while Portal2 is associated with all 25 PortalProducts for a full month.
Each PortalProduct contains 20 ProductRestEndpoints, giving Portal1 a total of 10 PortalProducts and 200 ProductRestEndpoints, and Portal2 a total of 25 PortalProducts and 500 ProductRestEndpoints.
Portal1 charges:
First 10 PortalProducts, each with up to 40 ProductRestEndpoints are included in the per Portal monthly charge of $125
Each additional PortalProduct is charged at $12.50 per month
Portals charges: $125
Additional PortalProducts charges: $0
Total for Portal1: 1 month * $125 = $125
Portal2 charges:
First 10 PortalProducts, each with up to 40 ProductRestEndpoints are included in the per Portal monthly charge of $125
Each additional PortalProduct is charged at $12.50 per month
Portals charges: $125
Additional PortalProducts charges: 15 Additional PortalProduct charges: 1 month * 15 PortalProducts * $12.50 = 15 *$12.50 = $187.5
Total for Portal2: $125 + $187.5 = $312.5
Total APIGateway-Portals charges: $125 + $312.5 = $437.5 for the month
