# Tillpad > Bounded storage and search for agent jobs Metered helpers agents can economically operate inside: KVP, memory conventions, RAG, receive-only email inboxes, scheduled HTTPS jobs, budget tools, run/sub keys, REST + MCP. Tillpad Pro is $9/month for humans (auto-renew + metered overage) or $9/30 days prepaid for agents via Stripe MPP. Unpaid accounts have no usable remaining quota; after subscribing you get included monthly usage, then Stripe overage up to the spend ceiling. ## Start here - [Scratchpad quickstart](https://tillpad.dev/scratchpad.txt): mint run key → store → search → wipe → receipt (~5 min) - [Human walkthrough](https://tillpad.dev/docs/scratchpad): same loop in the UI ## Auth - Humans: email OTP → session JWT - Agents (zero-human): `POST https://tillpad.dev/api/agents/bootstrap` → `POST https://tillpad.dev/api/billing/machine-pay` with bootstrap JWT → `tp_…` account key on settle (first call returns HTTP 202 `verification_required` and emails a 6-digit code; repeat with `code` to get the bootstrap JWT) - Agents (with key): Bearer API key `tp_…` (account, run, or scoped sub key) - Active Pro required to create keys and run metered work (local may use BILLING_DEV_BYPASS) ## Agent SKUs (MPP) See `GET https://tillpad.dev/api/config` → `plans.agentSkus`: `pro_prepaid_30d` ($9/30d), `pro_prepaid_90d` ($24/90d), top-ups `topup_kvp_10k`, `topup_storage_1gb` (require active Pro). ## Essential links - [Docs](https://tillpad.dev/docs): Human getting started - [OpenAPI](https://tillpad.dev/openapi.json): Machine API contract - [API reference](https://tillpad.dev/swagger): Interactive try-it - [MCP](https://tillpad.dev/mcp): Remote MCP (Bearer API key) - [Budget](https://tillpad.dev/api/budget): Remaining quotas (auth required) - [Pricing](https://tillpad.dev/pricing): Human $9/mo sub + agent $9/30d prepaid - [Terms](https://tillpad.dev/terms) · [Privacy](https://tillpad.dev/privacy) · [Refunds](https://tillpad.dev/refunds) ## Discovery - [llms-full.txt](https://tillpad.dev/llms-full.txt) - [ai-plugin.json](https://tillpad.dev/.well-known/ai-plugin.json) - [mcp.json](https://tillpad.dev/.well-known/mcp.json) - [mcp/server.json](https://tillpad.dev/.well-known/mcp/server.json) - [mcp/server-card.json](https://tillpad.dev/.well-known/mcp/server-card.json) - [agent-card.json](https://tillpad.dev/.well-known/agent-card.json) - [sitemap.xml](https://tillpad.dev/sitemap.xml)
