Built for agents
Your agent signs you up, creates keys, and configures itself — zero dashboard clicks. Install the onboarding MCP and hand your agent one prompt.
Your first prompt
“Set me up with a Smarter Weather API key and configure the weather MCP.”
The onboarding flow, end to end
Anonymous discovery → OAuth (your agent's host prompts you once) → key creation → self-configuration. Twelve tools cover the whole account lifecycle:
| Tool | Auth | What it does |
|---|---|---|
get_plans | Anonymous | Compare plans and pricing |
get_documentation | Anonymous | Fetch docs for any surface |
get_quickstart | Anonymous | Step-by-step integration guide |
sign_up | Anonymous | Start the request-access flow |
create_api_key | OAuth | Mint a key (idempotent) |
list_api_keys | OAuth | Enumerate your keys |
rotate_api_key | OAuth | Rotate a compromised key |
revoke_api_key | OAuth | Revoke a key |
configure_mcp | OAuth | Emit ready-to-paste MCP config |
get_usage | OAuth | Current-cycle usage and limits |
get_billing_status | OAuth | Plan, invoices, payment state |
upgrade_plan | OAuth | Start a plan-upgrade checkout |
Machine-readable everything
Every claim on this page is backed by a live artifact your agent can fetch and verify in under a minute:
Agent Skills
Installable procedural knowledge in the open SKILL.md standard (Claude Code, Cursor, Codex CLI, Gemini CLI, Copilot, and more). Point your agent at a skill URL or drop it into your skills directory:
smarterweather-apiREST integration: auth, endpoints, RFC 7807 errors, rate-limit handling.
smarterweather-mcpMCP install and onboarding flow, plus keyless x402 pay-per-call access.
Discovery index: /.well-known/skills/index.json — also listed in llms.txt.
MCP Apps widgets
Onboarding tools return interactive widgets that render inside MCP-Apps-capable hosts — sign-up, usage, configuration, and upgrades without leaving the conversation:
sign_up
get_usage
configure_mcp
upgrade_planAgentic payments (x402)
Agents with wallets can pay per call — no account, no API key. The weather MCP advertises in-band x402 payment requirements (USDC on Base); discovery tools like search_locations, reverse_geocode, list_datasets, and describe_dataset stay free, and paid tools start at $0.01 per call.
- Agent calls a paid tool keylessly and receives payment requirements in-band.
- Agent signs a USDC payment authorization with its wallet.
- Retry with proof — the tool executes and the settlement receipt returns in metadata.
Prefer a metered plan? Keys via the onboarding MCP above work on the same endpoint — see pricing.
Then: the weather MCP
Once your agent has a key (or a wallet), point it at the weather MCP — 28 tools for forecasts, alerts, radar, probabilistic guidance, and raw model data. See the tool reference.
