Pricing

Price per call is set in the package.json file.

{
  "name": "@bundle/functionName",
  "version": "1.1.26",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "bantam": {
    "memory": 256,
    "timeout": 30,
    "publicPrice": 0.05
  },
  "author": "me",
  "license": "ISC",
  "private": true,
  "dependencies": {}
}

To determine what your minimum publicPrice should be, choose a combinations of memory and timeout to find the max charge you will incure before your function times-out. NOTE: If your function calls other Bantam functions (for example @simple/file-download), you should include those fees in your price.

Bantam pricing structure:

Memory   /   Timeout   /   Price

128    /   5     /  0.00006067
128    /   30    /  0.00011401

256    /   5     /  0.00007134
256    /   30    /  0.00017803

512    /   5     /  0.00009268
512    /   30    /  0.00030605

1024   /   5     /  0.00013535
1024   /   30    /  0.0005621

2048   /   5     /  0.0002207
2048   /   30    /  0.0010742

3008   /   5     /  0.00030072
3008   /   30    /  0.0015543

The minimum allowed publicPrice is the Bantam price per call. For example, if your function needs 128 megabytes of memory with a 30 second timeout, then the publicPrice must be at least 0.00011401.

Then, depending on the publicPrice you choose, your bantam config object would then look something like:

"bantam": {
    "memory": 128,
    "timeout": 30,
    "publicPrice": 0.05
  },

Once your have finalized your function, running bantam publish will submit your new pricing structure.

Keep in mind when publishing a config with the bantam config object { "bantam": { public: false } }, your function will not be public to Bantam users. To make your function PUBLIC,set public to true before running bantam publish. For more information about public and private functions, check out our docs here

Updating price

To protect you and your users. Once a function is used by outside users, you cannot raise the publicPrice by more than 50% in a 30 day timespan. Therefore make sure you select a reasonable starting price.
