Authorize and monetize autonomous machine purchases without fraud risk

Digital merchants and SaaS platforms are unintentionally blocking high-intent machine buyers because legacy checkout flows trigger CAPTCHAs, 3D-Secure alerts, and immediate fraud flags whenever autonomous agents attempt to pay.

Vendic delivers an agent-native payment gateway that validates cryptographic spending mandates, enforces delegated human budget caps, and executes instantaneous machine-to-machine checkout. By adding 1 lightweight SDK, merchants can automatically authenticate agentic purchases without changing their underlying Stripe or Adyen merchant accounts. This eliminates accidental runaway billing loops and completely protects businesses against chargebacks through programmatic pre-authorization.

As software agents evolve into high-frequency economic actors, Vendic establishes the global transaction and settlement layer for the emerging machine economy.

Problem
  • When I run a SaaS or API business, I want to sell subscriptions and usage credits to autonomous workflows, but legacy payment gateways trigger CAPTCHAs and fraud rejections causing a 40% checkout failure rate.
  • Why Now: Autonomous coding agents, browser assistants, and workflow bots are executing complex multi-step operations and now require direct purchasing authority to complete tasks autonomously.
  • When I deploy autonomous enterprise bots, I want to delegate bounded purchasing authority for compute and tools, but sharing raw corporate credit cards risks runaway billing loops exceeding $10k overnight.
  • When I operate an online marketplace, I want to allow software agents to buy digital goods instantly, but traditional chargeback rules hold merchants liable for unauthorized machine actions.
  • Existing Alternatives: Manual human approval requests in Slack, prepaid virtual cards with clunky browser automation, or custom internal billing microservices that take months to build.
Solution
  • High-Level Concept: Stripe for Autonomous Agents: A cryptographic checkout infrastructure that validates agent identity, enforces budget envelopes, and settles payments instantly.
  • Drop-in Machine Checkout SDK: Allows SaaS and digital merchants to expose verified agent endpoints that bypass browser CAPTCHAs safely.
  • Cryptographic Delegated Envelopes: Enables human budget holders to sign time-limited, merchant-locked spending mandates with strict maximum thresholds.
  • Zero-Liability Fraud Protection: Programmatic pre-flight verification that guarantees funds and eliminates merchant chargeback risk on machine transactions.
Distribution
  • Early Adopters: High-volume API providers, AI developer toolmakers, and cloud compute platforms losing money on failed programmatic checkouts.
  • Direct integration partnerships with top autonomous agent frameworks (LangChain, AutoGPT, CrewAI) as their default payment module.
  • Developer documentation marketing targeting technical founders and devops engineers building autonomous agent infrastructure.
  • Pre-built plugin ecosystem for Stripe App Marketplace, Shopify App Store, and modern developer billing platforms.
Pricing
  • Value Ladder: Developer Tier ($0/month + 1.2% per transaction)
  • Growth Tier ($199/month + 0.8% per transaction)
  • Enterprise Custom (Volume tiering + dedicated indemnification pool).
  • One Metric That Matters [OMTM]: Total Machine Transaction Volume (MTTV) settled through verified cryptographic envelopes.
  • Market Sizing: Capturing 2% of the initial $4B autonomous workflow and API monetization market yields $80M in annual transactional fees by Year 3.
Scale Costs
  • High-throughput low-latency cryptographic validation nodes running across multi-region edge clusters.
  • Underwriting reserve capital and insurance bonding for zero-liability fraud indemnification guarantees.
  • Enterprise banking rail integration fees and global PCI-DSS Level 1 compliance maintenance.
