API docs: https://ai-psychologist-api.replit.app/docs

Key Facts

• Languages: English and Spanish
• Response time: 5 minutes to 10 hours (real human, UTC-3 timezone)
• Max 300 words per message
• Rate limit: 5 messages per minute per session
• First message: FREE. After that: $0.50 USDC on Base mainnet

Complete Workflow

Step 1 — Create a session

Use WebFetch to POST to

https://ai-psychologist-api.replit.app/start_session

(no body needed).

Expected response:

{"session_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", "message": "Session created. First message is free..."}

Save the

session_id

. You need it for all subsequent calls.

Step 2 — Send your FIRST message (FREE)

Use the user's argument (

$ARGUMENTS

) or ask them what they'd like to say. Max 300 words.

Use WebFetch to POST to

https://ai-psychologist-api.replit.app/send_message?session_id=SESSION_ID

with header

Content-Type: application/json

and body:

{"content": "YOUR MESSAGE HERE"}

Expected response (HTTP 200):

{"status": "delivered", "message_id": 1, "note": "Human response may take 5 min to 10 hours. Poll /get_response to retrieve it."}

Step 3 — Tell the user what happened

After sending, inform the user:

1. Their message was delivered to a real human psychologist
2. Give them the

   session_id

   so they can check for responses later
3. Response time is 5 minutes to 10 hours — this is normal
4. They can check for replies by invoking this skill again with:

   check SESSION_ID

Step 4 — Poll for the human's reply

Use WebFetch to GET

https://ai-psychologist-api.replit.app/get_response?session_id=SESSION_ID

Response when no reply yet:

{"session_id": "...", "responses": [], "note": "Human response may take 5 min to 10 hours. Poll every 30-60s."}

Response when reply is available:

{"session_id": "...", "responses": [{"message_id": 2, "content": "The psychologist's reply text", "timestamp": 1234567890.0}], "note": "Responses retrieved."}

If

responses

is empty, tell the user: "No reply yet. The psychologist is a real human and may take up to 10 hours. Try again later."

Step 5 — Send follow-up messages (REQUIRES PAYMENT)

After the first free message, every message costs $0.50 USDC on Base mainnet.

When you send a message without payment, the API returns HTTP 402 with the wallet address and payment instructions. Follow those instructions:

1. Transfer the requested USDC amount to the wallet shown in the 402 response
2. Get the transaction hash (0x...)
3. Include it in the request body as

   x402_payment

Use WebFetch to POST to

https://ai-psychologist-api.replit.app/send_message?session_id=SESSION_ID

with header

Content-Type: application/json

and body:

{"content": "YOUR FOLLOW-UP MESSAGE", "x402_payment": "0xYOUR_TX_HASH_HERE"}

The server verifies the USDC transfer on-chain before delivering the message. Each tx hash can only be used once.

Step 6 — Check session info (optional)

Use WebFetch to GET

https://ai-psychologist-api.replit.app/session_info?session_id=SESSION_ID

Response:

{"session_id": "...", "created_at": 1234567890.0, "free_message_used": true, "messages_sent": 1, "messages_received": 1, "payments": 0, "total_paid_usd": 0.0}

Error Handling

HTTP Code	Meaning	What to do
200	Success	Continue normally
400	Message too long (>300 words)	Shorten message, retry
402	Payment required or invalid	Read error detail. Either send USDC and include tx hash, or fix the tx hash issue
404	Session not found	Create a new session with POST /start_session
429	Rate limited (5/min)	Wait 60 seconds, then retry
