Probe runs 44 automated compliance and security checks on any API endpoint in under 5 seconds.

Built for AI agent developers and API providers who need to verify trust, security, and regulatory readiness before integration โ€” or before an agent makes its first payment.

Compliance & Regulatory - EU AI Act Article 14 โ€” human oversight signals - FATF Travel Rule readiness - Terms of Service and Privacy Policy endpoint detection - MiCA-relevant metadata checks

Agent Infrastructure - x402 payment protocol support - ERC-8004 on-chain agent identity verification - MCP server discovery - agent.json and Google A2A protocol detection

Security & Trust - SSL/TLS configuration and certificate health - DNSSEC, CAA, DMARC/SPF email authentication - Authentication maturity (OAuth2, OIDC, API keys) - Content-Type, CORS, and security headers

API Standards - Versioning and deprecation (Sunset headers) - Rate limiting and error handling - Response format consistency

How it works: - Instant audit โ€” no signup, no API key - Results in under 5 seconds - Pass/fail for each of the 44 checks - Overall compliance score (0-100) - Public leaderboard ranking 200+ APIs - JSON API for CI/CD pipelines - Free tier available

In an economy where agents choose which APIs to trust and pay, Probe is the credit check that runs before the first transaction.

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing GetProbe.xyz and Nullstack.

What makes your product unique?

GetProbe.xyz's answer

Probe is the only tool that checks AI agent-specific protocols like x402 payment headers, ERC-8004 on-chain identity, and EU AI Act Article 14 human oversight signals โ€” alongside traditional security checks like SSL/TLS, DNSSEC, and DMARC. No other compliance scanner covers the AI agent economy stack.

Why should a person choose your product over its competitors?

GetProbe.xyz's answer

Most compliance tools focus on GDPR or generic web security. Probe covers 32 checks across both traditional security AND emerging AI agent protocols (x402, MCP, agent.json, Google A2A). It runs in under 5 seconds, requires no signup, and provides a public leaderboard so you can benchmark against 200+ APIs instantly.

How would you describe the primary audience of your product?

GetProbe.xyz's answer

AI agent developers, API providers, DevOps engineers, and compliance teams who need to verify that APIs meet security, trust, and regulatory standards before integration. Especially relevant for teams building in the x402/MCP/A2A agent economy.

What's the story behind your product?

GetProbe.xyz's answer

We built Probe because AI agents are starting to pay for and consume APIs autonomously โ€” but there was no way to verify if an API is trustworthy before an agent sends money to it. Probe started as an internal tool at AsterPay to audit x402-compatible APIs, then grew into a standalone compliance platform covering 32 checks across security, identity, and regulation.

Which are the primary technologies used for building your product?

GetProbe.xyz's answer

Cloudflare Pages & Pages Functions (serverless edge), Supabase (PostgreSQL), vanilla JavaScript (zero framework frontend), DNS-over-HTTPS for DNSSEC/DMARC checks, Certificate Transparency logs for SSL analysis, and on-chain RPC calls for ERC-8004 verification.

Who are some of the biggest customers of your product?

GetProbe.xyz's answer

  • x402.org
  • Firecrawl
  • Pinata
  • Neynar
  • Bitrefill
  • NVIDIA API
  • Stripe API
  • OpenAI API
