What is Callable?
Callable is an AI agent infrastructure tool that completes human-required verifications which block autonomous AI agents, such as KYC checks, account sign-ins, CAPTCHAs, and identity confirmations. It is built for developers running AI agents that hit verification walls during autonomous operation and need a human to clear them. When an agent encounters a task it cannot complete on its own, Callable dispatches a real human operator working on actual hardware to perform the verification, then returns a structured JSON response plus a screenshot as proof, with a 30-minute turnaround deadline. Example tasks include Gmail sign-in verification, completing a KYC flow, and confirming a Stripe account. Callable supports agent-native payments through Stripe's Machine Payments Protocol (MPP) and the Link Agent Wallet, and offers a developer fallback that uses saved Stripe cards. Pricing is pay-as-you-go at $39 per verification task with no subscription required, so teams pay only for the verifications they actually need. By handling the human-in-the-loop steps that automated agents cannot, Callable lets developers keep agent workflows running through identity and verification gates that would otherwise stall them.

Pros and cons
Pros
- Dispatches a real human operator to complete KYC, sign-ins, CAPTCHAs, and identity checks that block agents
- Returns structured JSON plus a screenshot as proof within a 30-minute deadline
- Agent-native payments via Stripe Machine Payments Protocol (MPP) and Link Agent Wallet
- Flat pay-as-you-go pricing at $39 per task with no subscription
Cons
- $39 per task can add up for high-volume verification workflows
- Relies on human operators, so the 30-minute turnaround is slower than instant automation
- Scope is narrow — focused on verification gates rather than general agent tasks
- Routing real credentials and identity steps to a third party raises trust and security considerations
