Jentic publishes the only available OpenAPI specification for Axonaut API, keeping it validated and agent-ready. Axonaut is an all-in-one CRM and small-business management platform popular with French SMBs. The v1 API exposes contacts, invoices, quotations, expenses, projects, and opportunities with create, read, and update operations, supporting both sales-pipeline workflows and accounting integrations. Authentication uses an API key passed in the userApiKey header.
Install Jentic One Beta
Connect the Axonaut API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Axonaut 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://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | 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.
Capabilities
What an agent can do with Axonaut API.
Create, list, retrieve, and update contacts in the Axonaut CRM
Issue and track invoices through the /invoices endpoints
Generate and list sales quotations for prospects and customers
Record and list business expenses by category and date
Create and list projects associated with customers and opportunities
Track sales opportunities and pipeline stages via the /opportunities endpoints
Use Cases
Patterns agents use Axonaut API for, with concrete tasks.
★ Quote-to-Cash Automation
SMB ops teams can automate the path from prospect to invoice by chaining /quotations and /invoices. A signed quote can be converted into an invoice via POST /invoices once accepted, keeping accounting and CRM aligned. Suited to consultancies and agencies that bill against fixed-price quotes.
Create a quotation via POST /quotations for a prospect, then on acceptance create an invoice via POST /invoices referencing the same contact
CRM Contact Sync from Lead Sources
Marketing automation tools can push captured leads into Axonaut as contacts via POST /contacts and update them on subsequent enrichment via PUT /contacts/{id}. Pair with /opportunities to create a pipeline entry once the contact is qualified. Useful for unified contact records across acquisition channels.
POST /contacts with the new lead's details and create an opportunity via POST /opportunities tied to that contact id
Expense and Project Tracking
Finance teams can log business expenses against categories via POST /expenses and tie work to /projects so cost reporting reflects actual project P&L. The list endpoints support periodic reconciliations against bank or card statements. Suited to professional-services teams running multiple concurrent client engagements.
POST /expenses with a categorised business expense and link it to the active project by id for accurate project cost tracking
Agent-Driven Pipeline Updates via Jentic
A revenue-ops agent can refresh contacts, opportunities, and invoices in Axonaut on a schedule via Jentic without holding the userApiKey. Jentic exposes the contact, opportunity, and invoice operations as discoverable tools the agent can chain. Suited to revenue copilots that keep CRM and books in sync.
Search Jentic for 'list axonaut opportunities', load GET /opportunities, and execute it to retrieve the current pipeline for a weekly review

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
Axonaut user API keys are stored encrypted in the Jentic vault and injected into the userApiKey header at request time. Agents never see the raw key.
Intent-based discovery
Agents search Jentic by intent (e.g. 'create an invoice' or 'list opportunities') and Jentic returns the matching Axonaut operations with their input schemas attached.
Time to first call
Direct Axonaut integration: a few hours to wire userApiKey handling, pagination, and contact/invoice mapping. Through Jentic: minutes to make the first contact, invoice, or opportunity call.

FAQs
Specific to using Axonaut API through Jentic.
Why is there no official OpenAPI spec for Axonaut API?
Axonaut does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Axonaut API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Axonaut API use?
Axonaut uses an API key passed in the userApiKey header. Through Jentic, the key is stored encrypted in the vault and injected into the userApiKey header on every request.
Can I create invoices and quotations with the Axonaut API?
Yes. POST /quotations creates a sales quote and POST /invoices creates an invoice. Both are tied to a contact id so the records stay aligned with the CRM.
How do I track my sales pipeline through the Axonaut API?
Use GET /opportunities to list pipeline entries and POST /opportunities to add new ones. Pair with /contacts and /projects to keep the pipeline tied to the right customer and engagement.
What are the rate limits for the Axonaut API?
The Axonaut OpenAPI spec does not declare published rate limits. Axonaut enforces account-level quotas; back off on 429 responses if encountered when iterating across pages.
How do I list opportunities through Jentic?
Search Jentic for 'list axonaut opportunities', load GET /opportunities, and execute it. Jentic injects the userApiKey header and returns the current pipeline entries to your agent.
