How this service works
Payment-gated AI and browser automation API using the x402 protocol. All /v1/* endpoints require USDC payment on Base (eip155:8453) via x402 v2 exact scheme.
Output
Returns an emotion classification or set of emotion labels (e.g. joy, anger, sadness, fear, surprise, disgust) along with confidence scores, describing the emotional content of the provided input text.
Example use cases
Customer feedback emotion triage
“Run emotion detection on this customer support ticket: 'I love the new update, it made everything so much easier!' — tell me what emotion it expresses so I can route it appropriately.”
Social media sentiment monitoring
“Analyze the emotion in this tweet: 'Can't believe they cancelled the event again, I'm so disappointed' — what is the dominant emotion?”
Mental health chatbot tone detection
“Detect the emotional state expressed in this user message: 'I've been feeling really overwhelmed lately and don't know where to start' — I need to know if this signals distress.”
Technical details
Endpoint
POSThttps://x402.tanship.dev/v1/ai/emotionWhen to prefer
Choose this endpoint when you need lightweight, per-call micropayment-gated emotion detection without a subscription, especially in agentic pipelines that already use x402/USDC payments on Base. Ideal for low-volume or pay-as-you-go use cases where spinning up a dedicated NLP service is overkill.
Side effects
- Missing or malformed 'input' object returns a 400/422 validation error
- Insufficient USDC payment or missing x402 payment header returns HTTP 402 Payment Required
- Empty or unsupported body content may yield low-confidence or null emotion results
- Network or edge inference latency may cause occasional timeouts
- Unsupported bodyType values other than json/form-data/text will be rejected
