The Charity Engine Smart Proxy Post Processing (SP3) interface allows web data that is collected via Smart Proxy scripts to be processed by any application or execution environment available or supported by the Charity Engine network. This processing takes place on the same node that collects the data.
General Usage
To submit data for local processing on the proxy node, reference the autoloaded "charityengine" module in a Node.js smart proxy script, and call the desired processing function (*see Section 2 below for definitions of specific functions).
Processing functions return a Promise object, which resolves with the response from the model or application. By using await
, this response can then be used as appropriate within the Smart Proxy script and can be included in the crawl output.
For example, to generate embeddings for text collected using the Llama3.2 model:
charityengine.embeddings('llama3.2:3b', textCollectedFromCrawl);
To run a Docker container to calculate a mathematical sum using a custom script named "calc-sum.js":
charityengine.docker('node:slim', 'node /local/input/calc-sum.js 1 2 3 4.2', 'calc-sum.js');
To include multiple outputs, the responses from crawls and functions can be included in an object and returned from the Smart Proxy script, as the return value defines the job output.
Processing Functions
A variety of post-processing functions are available based on applications that are compatible with the Charity Engine network.
Docker Applications
Any image that can be pulled from Docker Hub, or that is publicly accessible on the web, can be used for post-processing by calling the docker()
function (*subject to specs of instance types used):
charityengine.docker(image, commandline, inputfile) PARAMETERS image // URL or Docker Hub name of the Docker image to run [string] [required] commandline // Command to execute within the container [string] [required] inputfile // Names of local files to use as input [array of string]
Execution Environments
The default execution environment is Node.js, per Section 1 above, "General Usage". For running source code or scripts in other interpreted languages, just download the execution environment of your choice from Docker Hub, following the instructions in Section 2.1 above. For example:
charityengine.docker("python:slim", "python /local/input/hello-world.py", ["hello-world.py"])
Charity Engine Application Library
Functions are also available for built-in applications that have been deployed to the Charity Engine network.
Note that some of these functions make use of proprietary software, which could incur additional runtime charges.
inference
Run LLM inference on a string
charityengine.inference(model, prompt, assets, context, system, template, options) PARAMETERS model // Name of the model to use [string] [required] prompt // Text to pass to the model as input [string] [required] assets // Images or files [array of string] context // Additional context for the model [string] system // System parameters for the model [string] template // Template to guide response format [string] options // Additional options for the request [object]
embeddings
Generate a vector embedding for a string
charityengine.embeddings(model, prompt) PARAMETERS model // Name of the model to use [string] [required] prompt // Text to pass to the model as input [string] [required]
wolframengine
Run Wolfram Language Code
charityengine.wolframengine(commandline, inputfile) PARAMETERS commandline // Command to execute within the application [string] [required] inputfile // Names of local files to use as input [array of string]
For example, to generate a chi-squared distribution with 22
degrees of freedom using Wolfram Engine:
charityengine.wolframengine('ChiSquareDistribution[22]');
vina
Run a protein-ligand binding simulation
charityengine.vina(commandline, inputfile) PARAMETERS commandline // Command line for the application [string] [required] inputfile // Names of local files to use as input [array of string]
blastp
Compare an amino acid sequence (protein sequence) against a protein sequence database
charityengine.blastp(commandline, inputfile) PARAMETERS commandline // Command line for the application [string] [required] inputfile // Names of local files to use as input [array of string]
See the Charity Engine Application Library for further details on the specific functionality of applications or execution environments.
