What does TaskBullet do?
TaskBullet’s Human Phone Calls API is built for agent builders who need last-mile help that software can’t complete. When your AI agent reaches a step that requires a human conversation, it can request a phone call through the TaskBullet Hub using MCP or REST. A real TaskBullet VA then makes the call, and your agent receives structured responses plus wrap-up notes to continue the workflow.
The API is designed for “connect once, call real tools” setups. You integrate with the TaskBullet Hub endpoint and authenticate with your hub key (optional in some cases). The phone-call workflow uses a dedicated live call key (tb_live_) and the calls wallet, which is separate from your hub key and is not the same as the “10 Hours On Us” trial.
TaskBullet also supports listing and routing for maker MCP servers: a listing stays pending until approved, and routing only happens when hub routing is enabled. For builders evaluating what’s possible, the hub provides available tool listings and call counts (shown as tool-call volume over the last 30 days), helping you track usage across callers.
Pricing is based on phone call time with a stated starting point of a $2.50 one-minute minimum. TaskBullet also offers related VA services for physical-world tasks and QA, with an intended role for human backup when an AI needs a person to finish the job.
How does TaskBullet’s Human Phone Calls API work for an AI agent?
Your agent requests a phone call via the TaskBullet Hub (MCP or REST). A human TaskBullet VA places the call, and the agent receives structured answers plus wrap-up notes to proceed.
Where does the phone-calling integration happen—Hub MCP or REST?
Both are supported. The hub MCP endpoint is https://taskbullet.com/api/hub/mcp, and you can also call the hub via REST using an x-api-key header.
Do I use the same API key for Hub tooling and live phone calls?
No. The live phone calls use a dedicated tb_live_ key and the calls wallet, which is not the same as the hub key used for the MCP hub connection.
Is this the same as the “Start Free — 10 Hours On Us” trial?
No. The live call key and call workflow are separate from the 10-hour trial referenced for the hub experience.
What billing model applies to phone calls?
Phone calls are time-based with a stated $2.50 one-minute minimum. Pricing details beyond that are not listed in the provided text.
Can I list my own MCP server in the TaskBullet hub?
Yes. A maker listing is submitted via the maker portal, remains pending until an admin approves it, and is routed only when hub routing is on.
