Callable

What is Callable?

Callable is an API-first platform that acts as a "humans as a function" layer for AI agents. When an AI agent hits a task it cannot complete autonomously—like account verification, video creation, or phone calls—Callable routes the task to a vetted human operator who executes it and returns a structured JSON result. The entire workflow is agent-native: the AI agent submits a task via a POST request, an expert picks it up, and the result is delivered to a callback URL within hours. It is designed to bridge the gap between AI automation and real-world tasks that require human intervention.

Application scenarios

Account creation
An AI agent needs a Gmail account created; Callable handles the sign-up and verification.
User-generated video
An agent requires a short product video; a vetted creator shoots and delivers a 20-second clip.
Phone calls
An agent needs to call a restaurant to confirm hours or make a reservation; a human operator makes the outbound call.
Form filling
An agent must submit complex government applications or sign-up forms; a human fills them out accurately.
Social media posting
An agent posts content from a real account with a real IP address to avoid detection.
Lead enrichment
An agent needs researched lead lists with emails, phones, and LinkedIn URLs; a human compiles them.

Core Features

Agent-native API
Submit tasks via a simple `POST /tasks` HTTP request with a JSON payload, including task type, input data, and callback URL.
Task types
Supports predefined task categories like `ugc_video`, `phone_call`, `form_filling`, `account_verification`, `authentic_posting`, and `lead_enrichment`.
Expert execution
Vetted human operators pick up tasks and execute them within a specified SLA (e.g., 600 seconds).
Structured results
Results are delivered as structured JSON to the callback URL, making them machine-readable.
Autonomous payment
Supports Stripe's Machine Payments Protocol (MPP) and Link Agent Wallet, allowing the AI agent to pay for tasks autonomously without a human in the loop.
Developer fallback
Register a saved card via Stripe Customer in the dashboard; every API call debits automatically, providing a fallback payment method.
Custom task requests
If a task type is missing, users can describe what their agent needs, and Callable builds support for it.

Target users

Callable is built for AI developers and teams building autonomous agents that need to complete real-world tasks. It is ideal for engineers working on agentic workflows, startups integrating AI with human-in-the-loop capabilities, and companies that want to extend their AI agents' abilities beyond digital automation.

How to use Callable?

Get an API key: Sign up at getcallable.dev and obtain your API key.
Submit a task: Send a POST /tasks request to api.getcallable.dev with the task type, input data, and callback URL.
Include payment: Either register a saved card in the dashboard or include a Link Agent Wallet credential in the request body for autonomous payment.
Receive results: The result is delivered as structured JSON to your specified callback URL within the SLA time.
Custom tasks: If your needed task type isn't listed, submit a request describing what your agent needs, and Callable will build it.

Pricing and free trial

Pricing is per task with no subscription. The listed prices are:

UGC Video: $99 per task
Phone Call: $49 per task
Account & Verification: $39 per task
Form Filling: $39 per task
Authentic Posting: $29 per task

There is no mention of a free trial on the site.

Effect review

Callable solves a genuine pain point for AI agents: tasks that require human judgment, physical presence, or real-world actions. The per-task pricing model is straightforward and predictable, making it easy to budget for agentic workflows. The support for Stripe's Machine Payments Protocol is a forward-thinking feature that enables fully autonomous agent operations. However, the platform's usefulness depends entirely on the quality and speed of the vetted operators, which is not detailed on the site. For developers building agents that need to handle edge cases beyond digital automation, Callable offers a practical and well-designed API interface.
