Use for: I need to form, I want to forms, Search for form, Find all form
Not supported: Does not handle communications, crm, or developer tools - use for payments only.
Submittable API for managing forms, submissions, funds, transactions, labels, messaging, and team members for grants and submissions management. The API exposes 26 endpoints secured with basic authentication.
Install Jentic One Beta
Connect the Submittable Grants Management API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Submittable Grants Management 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%2Fsubmittable.com%2Fsubmittable" | 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%2Fsubmittable.com%2Fsubmittable" | 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.

Use Cases
Patterns agents use Submittable Grants Management API for, with concrete tasks.
★ Payments Operations
Use the Submittable Grants Management API to perform payments operations programmatically. The API provides 26 endpoints covering core functionality including create form, list forms, update form.
Call POST /v4/forms to create form
Automated Forms Management
Automate forms operations by combining multiple Submittable Grants Management API endpoints. Agents can list forms and then update form in a single workflow.
Call GET /v4/forms to list forms, then verify the result
AI Agent Integration via Jentic
AI agents discover and call Submittable Grants Management 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 'create form', load the operation schema, and execute with Jentic-managed credentials

Why Jentic?
What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Submittable Grants Management API by hand means setting up its HTTP basic auth with your API key as the username and a blank password, then tracking form and entry ids yourself. Through Jentic you install once, import the Submittable Grants Management API from the API Directory, store the key once, and your agent calls it.
Permission scoping
Submittable puts the form id in the URL path (/v4/forms/{formId}), so a rule can pin your agent to one form: it can read and update that form and nothing else. You choose the operations it may call, so destructive ones like deleting a form are not included unless you add them.
Credential isolation
Your Submittable basic API key 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.
Intent-based discovery
Agents search Jentic by intent such as 'create a form' or 'submit an entry', and Jentic returns the matching Submittable operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs
Specific to using Submittable Grants Management API through Jentic.
What authentication does the Submittable Grants Management API use?
The Submittable Grants Management 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 create form with the Submittable Grants Management API?
Yes. Use the POST /v4/forms endpoint. The API returns structured JSON responses that agents can parse and act on directly.
What are the rate limits for the Submittable Grants Management 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 create form through Jentic?
Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create form'. Jentic returns the matching Submittable Grants Management API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.
How many endpoints does the Submittable Grants Management API have?
The Submittable Grants Management API exposes 26 endpoints covering forms, entries, funds operations.
Can I limit what my agent is allowed to do with the Submittable Grants Management API?
Yes. Jentic One is self-hosted by you, so your own rules decide which Submittable operations and credentials the agent can use. Because Submittable puts the form id in the URL path (/v4/forms/{formId}), a rule can pin the agent to a single form so it only reads and updates that form and nothing else. You also choose which operations it may call, so destructive ones like DELETE /v4/forms/{formId} stay off limits unless you explicitly add them.
