LEI data is published under a Creative Commons CC0 open data license. ## AI-native score: Unrated Available here: [Offers](#offers). Coverage measures research breadth across scored fields. Research coverage is 31/100. An AI-native grade requires 40/100. The provisional breakdown below shows the AI-native signals recorded so far. The AI-native score measures agent-readiness and is not a substitute for your own security or vendor-risk review. See [methodology](/methodology/) for how coverage and the grade are computed. | Component | Applies | Raw | Effective weight | Nominal weight | Contribution | | --- | --- | --- | --- | --- | --- | | Integration | Yes | 0/10 | 35% | 35% | 0.0 | | Trust | Yes | 0/6 | 30% | 30% | 0.0 | | Portability | Yes | 2/4 | 20% | 20% | 10.0 | | Security | Yes | 0/4 | 15% | 15% | 0.0 | - **Portability signals:** Open standards (+1); Standard protocol access (+1) ## Trust & Data Policy - **WebMCP:** – No - **Open standards:** ✓ Yes - **Standard protocol access:** ✓ Yes - **Not yet researched:** llms.txt, Headless signup, Multi-factor authentication, Zero data retention, No generative AI training, Hard budget caps, Sandbox environment, Data export, Data import, No proprietary-SDK lock-in, Documented provider swap, Self-hostable, Open source ## Confirmed absences These decision fields were researched and confirmed absent — not available based on current evidence, until contrary information supersedes the finding. Each carries the check performed, the page checked, and the date, so you can act on the negative without repeating the research. A label-scoped absence applies only to its label (e.g. no SOC 2 does not mean no certifications). - **A2A servers** — confirmed absent (whole field), checked 2026-10-18.
