Yespo API Catalog
2 APIs across 2 product groups. All share one credential.
Which Yespo API should I use?
| I want to... | Use | Why |
|---|---|---|
| Full omnichannel contact and messaging surface including email, SMS, push, Viber, Telegram, broadcasts, events, and account operations | Yespo API | Exposes 100 operations spanning the entire platform, the widest coverage of the two APIs. |
| Focused contact and marketing operations such as importing contacts, managing groups, triggering events, and reading contact activity | Yespo (eSputnik) Marketing API | A smaller 12-operation surface centered on contacts, groups, and campaign activity. |
| Add or update a single contact record | Yespo API | Both APIs support this, but the main API adds bulk, file import, and subscribe operations around it. |
Install Jentic One Beta
Connect the Yespo APIs to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Yespo APIs, 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%2Fyespo.io" | sh2
Step 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%2Fyespo.io" | 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.
Once connected, ask your agent something like: “manage contacts and send omnichannel messages with Yespo”.
Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring Yespo by hand means configuring HTTP basic auth against two base URLs and working through a large contact and messaging surface yourself. Through Jentic you install once, add the Yespo APIs from the Jentic directory, store the credential once, and your agent calls either API.
Permission scoping
Yespo puts contact and group ids in the URL path, so your own rules in your Jentic One instance can pin an agent to specific records or groups and decide which operations it may call. Destructive operations like deleting a contact or bulk imports are only available if you allow them.
Credential isolation
Your Yespo basic auth credential is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context, and the same credential covers both APIs.
FAQs
Specific to using Yespo APIs through Jentic.
What can an agent do across the Yespo APIs?
An agent can create, update, search, and delete contacts, manage contact group membership, import contacts individually or in bulk, trigger events, and send or broadcast messages across email, SMS, mobile push, Viber, and Telegram. It can also read contact activity and campaign data to inform later steps.
How do the two Yespo APIs differ?
The main Yespo API is the broad surface with 100 operations covering the full platform, including account, address books, broadcasts, and every messaging channel. The Yespo (eSputnik) Marketing API is a smaller 12-operation surface focused on contacts, groups, events, and campaign activity.
Do I need separate credentials for each API?
No. Both APIs use HTTP basic authentication tied to your Yespo account, so one username and password works across both the contact and marketing surfaces.
Is Yespo the same as eSputnik?
Yes. Yespo is the current name for the platform formerly known as eSputnik. The marketing API still carries the eSputnik name in its title, but both APIs are part of the same Yespo product.
