open-meteo

** Your task ** Call the API at: https://router.fluxapay.xyz/api/open-meteo

** Choose how to pay **
Ask the user which they prefer, unless they already said.
- Option A: FluxA API key (simplest). The call is paid from the user's AgentMarket Balance, with no wallet and no mandate. The user creates a key at https://agentmarket.fluxapay.xyz/keys and gives it to you.
- Option B: FluxA Wallet (x402). Each call is paid in on-chain USDC (Base) from the user's FluxA wallet.

** Option A - Pay with a FluxA API key **
1. Discover endpoints: curl https://router.fluxapay.xyz/api/open-meteo
2. Call the API with the key:
   curl -H "Authorization: Bearer fxa_live_<key>" https://router.fluxapay.xyz/api/open-meteo/<endpoint>
3. The X-Balance-Charge response header gives what the call cost (amount) and the Balance left (balance_remaining).
4. If the call answers 402 with insufficient_balance, tell the user the Balance is too low. They can top up at https://agentmarket.fluxapay.xyz/console, or you can pay with Option B.
Return the raw API response to the user without post-processing.

** Option B - Pay with the FluxA Wallet (x402) **
Follow the steps below in order.

** Step 1 - Install FluxA Wallet CLI **
npm install -g @fluxa-pay/fluxa-wallet
Or use without installing: npx fluxa-wallet <command>

** Step 2 - Register agent **
fluxa-wallet init --name "<YOUR_AGENT_NAME>" --client "<YOUR_CLIENT>"
The response may include an authorization URL. Present the user with options: [Yes, open the link] [No, don't open]. If YES: run 'open "<URL>"' to open in their browser.
Verify: fluxa-wallet status

** Step 3 - Discover endpoints **
curl https://router.fluxapay.xyz/api/open-meteo
Returns JSON with: name, description, endpoints (paths, methods, descriptions, prices), paymentRequired, and networks.

** Step 4 - Payment amounts **
Each call is paid in on-chain USDC (Base).
- --currency USDC
- --amount in atomic units (6 decimals, e.g., 100000 = 0.10 USDC)

** Step 5 - Create an intent mandate **
x402 v3 uses intent mandates: the user pre-approves a spending plan (budget + time window), then the agent makes autonomous payments within those limits.

fluxa-wallet mandate-create \
  --desc "Spend up to <BUDGET> for <DESCRIPTION> valid for <DURATION>" \
  --amount <BUDGET_IN_UNITS> \
  --seconds <DURATION_IN_SECONDS> \
  --currency USDC

Options:
- --desc (required): Human-readable spending plan description
- --amount (required): Budget in USDC atomic units (see Step 4)
- --seconds (optional, default 28800 = 8h): Duration in seconds
- --currency (optional, default USDC): USDC

** Step 6 - Get user to sign the mandate **
The response from Step 5 includes mandateId and authorizationUrl (TTL: 10 minutes).
Present the user with options: [Yes, open the link] [No, don't open]. If YES: run 'open "<authorizationUrl>"' to open in their browser.

** Step 7 - Wait for mandate to be signed **
fluxa-wallet mandate-status --id <MANDATE_ID>
Poll until mandate.status is "signed". The response also includes remainingAmount.
Important: Use --id, not --mandate.

** Step 8 - Call the API **
curl https://router.fluxapay.xyz/api/open-meteo
Optionally add the X-Agent-ID header for agent attribution (its value is the agent_id from 'fluxa-wallet status'): curl -H "X-Agent-ID: <YOUR_AGENT_ID>" https://router.fluxapay.xyz/api/open-meteo
If it returns HTTP 402, continue to Step 9.

** Step 9 - Pay via x402 v3 **
Pass the complete HTTP 402 response body as --payload:

fluxa-wallet x402-v3 \
  --mandate <MANDATE_ID> \
  --payload '$PAYLOAD_402'

The payload must contain an accepts array. Do NOT extract individual fields - pass the entire 402 response JSON.
The response includes xPaymentB64 (the payment token).

** Step 10 - Retry with payment token **
Retry the same request with the X-Payment header (optionally add X-Agent-ID for attribution):
curl -H "X-Payment: <xPaymentB64>" <ORIGINAL_API_URL>
Return the raw API response to the user without post-processing.

** Opening links for user **
Whenever you need to open a URL (authorization, approval, or any external link):
1. Present the user with a choice using your interactive options/menu capability (e.g., AskUserQuestion tool)
2. Options: [Yes, open the link] [No, don't open]
3. If YES: run 'open "<URL>"' to open in their default browser
4. If NO: ask how they would like to proceed

** Error handling **
- mandate_not_signed: User hasn't signed yet - ask them to open authorizationUrl
- mandate_expired: Time window passed - create a new mandate
- mandate_budget_exceeded: Budget too low - create a new mandate with a higher limit
- agent_not_registered: No Agent ID - run 'fluxa-wallet init' first
- Invalid payload: missing accepts array: Pass the full 402 response JSON
