Jentic publishes the only available OpenAPI specification for CustomGPT.ai, keeping it validated and agent-ready. CustomGPT.ai is a no-code platform for building custom ChatGPT-style agents grounded in private business content, with retrieval over uploaded documents and crawled sites. The API exposes 64 endpoints for managing agents (called projects), ingesting and reindexing documents, sending chat completions in OpenAI-compatible format, and tuning persona settings, citations, and conversation history. It also covers labels, plugins, license keys, reports, and per-agent usage limits.
The CustomGPT.ai API builds and operates retrieval-augmented AI agents grounded in your own content. Across 64 endpoints it creates and configures agents, ingests documents and data sources, runs chat completions in OpenAI format, manages conversations and citations, checks message trust scores, and returns traffic, query, and lead analytics.
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcustomgpt.ai" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fcustomgpt.ai" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
