IMPLEMENTATION
Call this tool
Connect a user's xAI account once, then configure and run Post Completion from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "x_ai-post-completion",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
x_ai: { authProvisionId: "apn_xxxxxxx" },
model: "Model",
prompt: "Prompt",
},
})
console.log(result)curl -X POST https://api.pipedream.com/v1/connect/{project_id}/actions/run \

Inputs
Pipedream supplies the connected account. Your application provides the operation-specific values below. Dynamic inputs are resolved against that user's account.
| Property | Type | Description |
|---|---|---|
model Model | string | ID of the embedding model to use Required Dynamic |
prompt Prompt | string | Prompt for the request Required |
echo Echo | boolean | Option to include the original prompt in the response along with the generated completion Optional |
frequencyPenalty Frequency Penalty | string | Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim Optional |
logprobs Log Probabilities | boolean | Include the log probabilities on the logprobs most likely output tokens, as well the chosen tokens Optional |
maxTokens Max Tokens | integer | Limits the number of tokens that can be produced in the output Optional |
n Completion Number | integer | Determines how many completion sequences to produce for each prompt. Be cautious with its use due to high token consumption Optional |
presencePenalty Presence Penalty | string | Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics Optional |
seed Seed | integer | If specified, our system will make a best effort to sample deterministically Optional |
stream Stream | boolean | Whether to stream back partial progress. If set, tokens will be sent as data-only server-sent events as they become available Optional |
suffix Suffix | string | Optional string to append after the generated text Optional |
temperature Temperature | string | What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic Optional |
topP Nucleus Sampling | string | An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered Optional |
user User | string | A unique identifier representing your end-user, which can help xAI to monitor and detect abuse Optional |
REFERENCE
Tool details
Behavior hints are published with the component in the Pipedream registry and surface as MCP tool annotations, so an agent can reason about a tool before it calls it.
