Building a Client

Implement a PLP client

Official SDKs

Use the official JavaScript or Python SDK to connect to any PLP-compatible server.

import { PLPClient } from "@goreal-ai/plp-client"

const client = new PLPClient("https://api.example.com/v1", {
  apiKey: "your-key"
})

const prompt = await client.get("welcome-email")

Building a Custom Client

A minimal PLP client needs to: check discovery, fetch prompts by ID, handle Bearer auth, and handle both string and multimodal content.

Content Handling

Prompts can have string or array content. The SDKs provide helpers:

import { isMultiModal, normalizeContent, getTextContent } from "@goreal-ai/plp-client"

isMultiModal(prompt)              // true if content is ContentPart[]
normalizeContent(prompt.content)  // Always returns ContentPart[]
getTextContent(prompt.content)    // Extracts text from any format

Using the Registry

Access any vendor through a stable registry URL — the registry returns a 307 redirect to the vendor's server:

const client = new PLPClient("https://registry.plp.dev/my-vendor/v1", {
  apiKey: "your-key"
})
