Not supported: Does not handle payments, communications, or developer tools - use for crm only.
RoboHash generates unique robot, monster, cat, human, or gorilla avatar images from any input text using deterministic hashing. Supports custom sizes, styles, backgrounds, and Gravatar integration. The API exposes 3 endpoints secured with basic authentication.
Install Jentic One Beta
Connect the RoboHash API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the RoboHash 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%2Frobohash.org%2Frobohash" | 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%2Frobohash.org%2Frobohash" | 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 RoboHash API.
Generate a PNG avatar image
Manage crm data programmatically
Integrate RoboHash API into automated workflows
Query and filter RoboHash API records by parameters
Monitor RoboHash API operational status and events
Use Cases
Patterns agents use RoboHash API for, with concrete tasks.
★ CRM Operations
Use the RoboHash API to perform crm operations programmatically. The API provides 3 endpoints covering core functionality including generate a png avatar image, generate a jpg avatar image, generate a bmp avatar image.
Call GET /{text}.png to generate a png avatar image
Automated Avatars Management
Automate avatars operations by combining multiple RoboHash API endpoints. Agents can generate a jpg avatar image and then generate a bmp avatar image in a single workflow.
Call GET /{text}.jpg to generate a jpg avatar image, then verify the result
AI Agent Integration via Jentic
AI agents discover and call RoboHash API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle basic tokens manually.
Search Jentic for 'generate a png avatar image', load the operation schema, and execute with Jentic-managed credentials

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the RoboHash API by hand means calling the robohash.org host directly with your text in the path to render a png, jpg, or bmp avatar and handling each image request yourself. Through Jentic you install once, import the RoboHash API from the API Directory, and your agent calls it without extra setup since this free API needs no credential.
Permission scoping
The path segment here is the text you want rendered rather than a resource you own, so scope the agent to the operations it needs, such as generating a png or jpg avatar: you decide which image formats it may request. Every operation the agent can run is one you have added to that allowed set.
Credential isolation
This RoboHash API needs no credential, so there is nothing for the agent to hold. Any keys you do configure in Jentic One are stored encrypted and injected at execution time, never entering the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'generate a png avatar' or 'render a robot image from text', and Jentic returns the matching RoboHash API operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using RoboHash API through Jentic.
What authentication does the RoboHash API use?
The RoboHash API uses HTTP Basic authentication with username and password. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.
Can I generate a png avatar image with the RoboHash API?
Yes. Use the GET /{text}.png endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the RoboHash API?
Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.
How do I generate a png avatar image through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'generate a png avatar image'. Jentic returns the matching RoboHash API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the RoboHash API have?
The RoboHash API exposes 3 endpoints covering avatars operations.
Can I limit what my agent is allowed to do with the RoboHash API?
Yes. Because Jentic One is self-hosted, you set the rules that decide which RoboHash operations your agent may call, so you can allow only the image formats you want it to render, such as GET /{text}.png while blocking the JPG and BMP endpoints. The path segment is just the text to render rather than a resource you own, so every operation the agent can run is one you have explicitly added to its allowed set. This API needs no credential, so scoping is purely about which of the three avatar operations you permit.
