Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Preuve Agent API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.
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%2Fpreuve.ai%2Fpreuve" | 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%2Fpreuve.ai%2Fpreuve" | 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.
What an agent can do with Preuve Agent API.
Start an asynchronous startup idea analysis with a clientRunId idempotency key and a starter or deep scanType
Poll an analysis for status, readyForExport, enrichment progress, and per-module statuses
Enrich a completed run with deep-only modules such as proofOfDemand, founderFit, playbook, trends, and community
Export a completed analysis as structured JSON at full or summary verbosity, including score, verdict, competitors, and market size
GET STARTED
Validate up to 5 ideas in one batch and export only the completed, export-ready items
Generate startup ideas synchronously from interests, budget, audience, and industry inputs
Create and export deep client reports against a shared Agency workspace quota
Patterns agents use Preuve Agent API for, with concrete tasks.
★ Agent-run idea validation loop
An AI agent helping a founder decide what to build can run a full Preuve validation without custom client code. Through Jentic the agent searches for 'validate a startup idea', calls createAnalysis with a starter scanType and a clientRunId, polls getAnalysis until readyForExport is true, and pulls the exportAnalysis JSON for the score, verdict, competitors, and market size. Because starter scans cost nothing, the agent can exercise the whole loop before switching to deep runs.
POST /api/agent/analyses with clientRunId 'coffee-supply-001', scanType 'starter', and the idea text, poll GET /api/agent/analyses/{id} until readyForExport is true, then GET /api/agent/analyses/{id}/export with verbosity 'summary'
Shortlisting several ideas at once
A founder weighing a handful of directions wants them scored side by side. The analysis-batches route accepts up to 5 items, each with its own clientRunId, and can mix starter and deep scans in one batch. The batch export includes only completed, export-ready items and lists every skipped one in omittedItems with a reason, so the comparison never silently drops an idea.
POST /api/agent/analysis-batches with a batch clientRunId, scanType 'starter', and three items each carrying a unique clientRunId and idea, then GET /api/agent/analysis-batches/{batchId}/export and rank the items by score
Deepening a promising idea
Once a starter or deep run looks promising, the enrich operation generates missing core export sections and can start deep-only modules such as proofOfDemand, founderFit, playbook, trends, and community. founderFit underwrites the idea against a founder profile covering hours per week, runway months, and team status, so the export reflects whether this founder can realistically ship it.
POST /api/agent/analyses/{id}/enrich with modules ['founderFit', 'playbook'] and a founderProfile of hoursPerWeek 20 and runwayMonths 6, then re-export the analysis
Consultancy client reports
A consultant running an Agency workspace can create deep client reports through the API against the shared project quota, list every report in the workspace newest first with limit and offset paging, and export the structured JSON of each completed report for a client deliverable.
POST /api/agent/agency/analyses with a clientRunId and a client's idea description, poll GET /api/agent/agency/reports/{id} until it completes, then GET /api/agent/agency/reports/{id}/export
14 endpoints — the preuve agent api validates startup ideas programmatically, returning a 0-100 viability score, competitors, market sizing, and source-linked evidence drawn from more than 60 live sources.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring Preuve by hand means sending the prv_ key in the x-preuve-key header, managing clientRunId idempotency, and writing the poll-until-readyForExport loop for asynchronous runs. Through Jentic you install once, import Preuve from the API Directory, store the key once, and your agent calls it.
Permission scoping
Preuve puts the analysis id in the URL path (/api/agent/analyses/{id}/...), so a rule can tie your agent to the analysis routes it needs. You choose which operations it may call, so quota-spending ones like createAgencyAnalysis or deep batch creation are not included unless you add them.
Credential isolation
Your Preuve API key is stored once, encrypted, by your own Jentic One instance and injected into the x-preuve-key header at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'validate a startup idea' or 'export an idea report', and Jentic returns the matching Preuve operation with its input schema, including clientRunId and scanType, so the agent calls the right endpoint without reading the docs.
Alternatives and complements available in the Jentic catalogue.
Specific to using Preuve Agent API through Jentic.
What authentication does the Preuve Agent API use?
Per its OpenAPI spec, the Preuve Agent API authenticates with an API key (prefixed prv_) sent as-is in the x-preuve-key header, with no signing and no bearer token. The discovery document at GET /api/agent is unauthenticated, while the analysis, batch, idea generator, and Agency operations expect the key. Through Jentic the key is held by your own instance and attached to each call.
Can I validate a startup idea for free with the Preuve Agent API?
Yes. Setting scanType to starter on POST /api/agent/analyses costs nothing and returns a real report, which makes it the sandbox for the create, poll, enrich, and export loop. A scanType of deep runs the full paid analysis and consumes account quota.
What are the rate limits for the Preuve Agent API?
The OpenAPI spec states that the idea generator gives free accounts 5 generations per rolling 24 hours and paid accounts a fair-use ceiling of 20 per rolling 24 hours. Rate-limited calls answer 429 with RATE_LIMITED and a Retry-After header. The unauthenticated GET /api/agent discovery document lists the current limits, and https://docs.preuve.ai/ has the full details.
Is there a Preuve MCP server?
You don't need an MCP server to give your agent the Preuve Agent API. Jentic connects it directly from the API Directory: import it, store your x-preuve-key once, and your agent calls the analysis operations on demand without loading another server's tool definitions into its context.
How do I validate an idea and export the report through Jentic?
Search Jentic for 'validate a startup idea', load createAnalysis, and execute it with a clientRunId, a scanType, and the idea text. Poll getAnalysis with the returned id until readyForExport is true, then call exportAnalysis for the structured JSON. To run it on your own infrastructure, install Jentic One from its GitHub repo.
Can I limit what my agent is allowed to do with the Preuve Agent API?
Yes. Write a rule that allows createAnalysis, getAnalysis, and exportAnalysis and leaves out createAgencyAnalysis, so the agent can run and read personal validations but cannot spend shared Agency project credits. Every call it makes is logged for review.
For Agents
Score a startup idea from 0-100 with competitors, market size, and cited evidence, then export the report as structured JSON. Starter scans cost nothing, so an agent can run the full create, poll, enrich, export loop as a sandbox.
Use for: I need to validate a startup idea before building it, Get the viability score and competitors for my product idea, Check whether an analysis run is ready for export, Retrieve the structured JSON report for a completed analysis
Not supported: Does not build products, register companies, or raise funding. Use for scoring and researching startup ideas only.
The Preuve Agent API validates startup ideas programmatically, returning a 0-100 viability score, competitors, market sizing, and source-linked evidence drawn from more than 60 live sources. Analyses run asynchronously: you start one with a clientRunId idempotency key and a scanType of starter (no cost) or deep (paid quota), poll it, enrich the completed run with deep-only modules such as proofOfDemand, founderFit, or playbook, and export a structured JSON report. Batches of up to 5 ideas, a synchronous idea generator, and Agency workspace client reports round out the surface.
