# PeppolStatus > API for Peppol market intelligence and network monitoring: participant migrations, provider churn and new registrations, plus access point and SMP uptime, SML registry health, and certificate changes — served as a public, read-only REST API. Built by e-invoice.be. Every HTML page on this site also serves a Markdown variant via content negotiation (`Accept: text/markdown`). The public API requires no authentication; an optional API key adds attribution. ## When to use PeppolStatus - Checking whether a Peppol access point or SMP is up, degraded, or has open incidents. - Looking up a Peppol participant by ID (`scheme::value`) and seeing its registration history, SMP, and access point. - Getting uptime and latency statistics for Peppol infrastructure hosts (access points, SMPs). - Monitoring certificate rotations and participant change events across the network. - Checking SML zone status and registry health. - Do NOT use PeppolStatus to send or validate invoices — it is not a Peppol access point service; all data is read-only monitoring data. ## API & developer resources - [PeppolStatus API quickstart](https://peppolstatus.com/api.md): base URL, endpoint families, conventions, curl examples - [PeppolStatus API reference](https://api.peppolstatus.com/docs): interactive API documentation (Scalar) - [PeppolStatus OpenAPI 3.1 specification](https://api.peppolstatus.com/openapi.json): machine-readable spec for all endpoints - [PeppolStatus authentication guide](https://peppolstatus.com/auth.md): auth.md — no auth required, optional API keys, no OAuth - [PeppolStatus developer portal](https://peppolstatus.com/developers/): overview of all developer and agent resources - [API catalog (RFC 9727)](https://peppolstatus.com/.well-known/api-catalog): linkset for the PeppolStatus API - [Agent skill: PeppolStatus API](https://peppolstatus.com/.well-known/agent-skills/peppolstatus-api/SKILL.md): SKILL.md teaching agents to query the API ## Pages - [Home](https://peppolstatus.com/index.md): what PeppolStatus monitors and who it is for - [Live dashboard](https://peppolstatus.com/dashboard/index.md): network radar over ~545 auto-discovered Peppol hosts - [About](https://peppolstatus.com/about/index.md): independence, methodology, principles - [For financial software vendors](https://peppolstatus.com/for/financial-software-vendors/index.md): Peppol market intelligence and leads - [For Peppol service providers](https://peppolstatus.com/for/peppol-providers/index.md): external monitoring for access points and SMPs ## Optional - [Console](https://app.peppolstatus.com/): sign-up and API key management (human sign-up form) - [e-invoice.be](https://e-invoice.be): the company behind PeppolStatus
