# Mepa8 > Monitor Every Paid API. Monitor every paid API. Cap any one of them. Mepa8 is a vendor cost and health monitor for small teams building AI products: it reads each metered vendor (ElevenLabs, Neon, Railway, Cloudflare, Twilio, Anthropic and others) by API, shows cost against budget on one board, alerts by text and email, and offers a two-step, reversible kill switch. A product of InboundAI365, LLC. Contact ryan@ib365.ai. ## Pages - [Book a vendor audit](https://mepa8.com/audit/): Read-only keys or a month of receipts in. Every vendor with real cost, each leak with its fix and rollback, and a board you keep. $750, five days. - [Mepa8 — Monitor every paid API](https://mepa8.com/): Mepa8 watches every metered vendor an AI team pays, shows cost against budget on one board, texts you before the invoice, and cuts any vendor off in two steps. - [ElevenLabs at 106%: one course rendered three times](https://mepa8.com/incidents/elevenlabs-106-percent/): We blamed the phone agents for an ElevenLabs overage. The usage API said 2.97M of 4.15M credits were batch text-to-speech on four September days. The trace. - [Incidents](https://mepa8.com/incidents/): Our own vendor bills, in public: Neon at $93 a month, ElevenLabs at 106% of its credits, Railway pausing six projects. The numbers, the causes, the fixes. - [Why our Neon bill reached $93 a month](https://mepa8.com/incidents/neon-100-dollar-bill/): One sync job rewrote every row of a table every 5 seconds, so Neon's compute never slept. The numbers, the trigger that stopped it, the alert that should have fired. - [Railway paused six projects on an expired trial](https://mepa8.com/incidents/railway-trial-paused/): A trial ended, a card failed, an invoice went unpaid, and six Railway projects stopped deploying. CI had been red for 14 days and nobody knew. Timeline and fix. - [Pricing](https://mepa8.com/pricing/): Priced on what it watches, not seats. Free for 3 vendors with email alerts. Pro $49 a month adds SMS, the kill switch and the agent API. Team $149. Audit $750 once. - [Privacy](https://mepa8.com/privacy/): Plain words: the audit form stores 6 fields in one database and sends one email. No ad trackers, no analytics cookies. Vendor keys are never stored as values here. - [How to cap your Cloudflare bill](https://mepa8.com/vendors/cloudflare/): What Cloudflare Workers and D1 bill for, the account-wide free-tier limit that broke one of our products, and how Mepa8 watches it. - [How to cap your ElevenLabs bill](https://mepa8.com/vendors/elevenlabs/): What ElevenLabs bills for, how one re-rendered audio course pushed us to 106% of our credits, and how Mepa8 watches the subscription endpoint so it is never unseen. - [How to cap your HeyGen bill](https://mepa8.com/vendors/heygen/): What HeyGen bills for, why a wallet with auto-reload off is already a hard cap, and how Mepa8 reads the balance by API so you know before it runs dry. - [Vendor catalog](https://mepa8.com/vendors/): The 21 vendors Mepa8 watches today, each with a tier that says exactly how much of the watching is automatic, and the rule a vendor must pass to join. - [How to cap your Neon bill](https://mepa8.com/vendors/neon/): Neon bills by compute hour, so anything that never lets the database sleep is the bill. How a 5-second sync cost $100 a month and how Mepa8 reads churn in Postgres. - [How to cap your Railway bill](https://mepa8.com/vendors/railway/): Railway bills per second of CPU and memory, pauses everything when a trial or card fails, and can sit weeks behind main. Set its hard limit; let Mepa8 watch deploys. ## Facts - Pricing: Free (3 vendors, email alerts), Pro $49/month, Team $149/month, Vendor audit $750 one-time.
