Sats4AI - Bitcoin-Powered AI Tools

skills: {'id': 'create_payment', 'name': 'create_payment', 'description': 'Create a Lightning invoice to pay for one AI service call. Returns JSON: { paymentId, invoice (BOLT11), amount (sats), expiresAt }. Each payment covers exactly one tool call — call this once per operation. Typical flow: list_models → create_payment → check_payment_status → call tool. The invoice expires in 10 minutes. Call list_models first to discover modelId values. modelId is optional — omit it to use the default (best) model. Some tools require extra params at payment time because pricing depends on them: generate_text requires prompt (price = f(char count)); send_sms, place_call, ai_call require phoneNumber; generate_video requires duration, mode, generate_audio; animate_image requires duration (100 sats/sec); edit_image requires resolution (1K=200, 2K=300, 4K=450 sats). If required params are missing, the response includes an error with the missing field names.', 'tags': [], 'examples': None, 'input_modes': None, 'output_modes': None}, {'id': 'check_payment_status', 'name': 'check_payment_status', 'description': "Check whether a Lightning invoice has been paid. Returns JSON: { status: 'paid' | 'pending' | 'expired', paymentId }. Call after create_payment to verify the user has paid before calling the target tool.
