How this service works
Academic web presence and research platform of Dr. Watcharin Sarachai — Information Technology, Maejo University.
Output
Returns a JSON object containing a response id, a URL, a slug, width, height, fileName, fileSize, and mimeType — though the endpoint is a chat API, the documented response schema appears to describe an image upload response, suggesting possible schema mismatch; agents should expect a conversational text reply wrapped in a JSON body.
Example use cases
Academic Q&A assistant for students
“I'm studying information technology and need a quick explanation of database normalization — can you send my question to the Sarachai chat API and get me an answer?”
Multi-turn research dialogue
“I want to have a back-and-forth conversation about neural network architectures — send my previous three messages and the latest follow-up question to the Sarachai chat endpoint and get the next response.”
Quick factual lookup via AI chat
“Ask the Sarachai AI chat: 'What are the main differences between supervised and unsupervised learning?' and show me what it says.”

Endpoint
POSThttps://sarachai.com/api/x402/chat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost ($0.01 USDC per call), x402-payment-gated conversational AI chat capability and are comfortable with an academically-hosted service. It is suitable for lightweight chat interactions, especially in x402-protocol-aware agent workflows where micropayment per call is acceptable.
Side effects
- Payment not provided or insufficient USDC results in HTTP 402 error
- Messages array is empty or missing required role/content fields causes validation failure
- Content exceeds 4000 character limit per message triggers rejection
- More than 40 messages in the array may be refused
- Service unavailability from the academic hosting domain
