REST API

Create chatbots, send messages and read analytics from your own backend.

Authentication

Every request needs an API key as a bearer token. Create one in Settings → API keys; it is shown once and stored only as a hash, so we genuinely cannot recover it for you.

Session cookies are deliberately not accepted, which means the API cannot be driven by a cross-site request from a signed-in browser.

bash

curl https://anserra.onzira.com/api/v1/chatbots \
  -H "Authorization: Bearer ans_live_…"

Scopes

A key carries only the scopes you grant it. Using an endpoint outside a key's scopes returns 403 with the scope it needed.

Scope	Grants
read	List chatbots, conversations and analytics
write	Create, update and delete chatbots and knowledge sources
chat	Send messages and receive answers

Endpoints

Method	Path	Scope	Purpose
GET	/api/v1/chatbots	read	List chatbots, cursor paginated
POST	/api/v1/chatbots	write	Create a chatbot
GET	/api/v1/chatbots/:id	read	Fetch one chatbot
PATCH	/api/v1/chatbots/:id	write	Update settings or publish
DELETE	/api/v1/chatbots/:id	write	Delete a chatbot and its data
POST	/api/v1/chat	chat	Ask a question
GET	/api/v1/conversations	read	List conversations and transcripts
GET	/api/v1/analytics	read	Metrics, top sources and content gaps

Sending a message

Returns the complete answer as JSON. Pass stream: true for Server-Sent Events instead. Either way the exchange is persisted and counts toward your plan exactly as a widget conversation would.

bash

curl https://anserra.onzira.com/api/v1/chat \
  -H "Authorization: Bearer ans_live_…" \
  -H "Content-Type: application/json" \
  -d '{
    "chatbot_id": "YOUR_CHATBOT_ID",
    "message": "Do you offer refunds on annual plans?"
  }'

Response

json

{
  "object": "chat_completion",
  "conversation_id": "cm…",
  "message": {
    "id": "cm…",
    "role": "assistant",
    "content": "Annual plans can be refunded in full within 30 days…",
    "citations": [{ "title": "Billing Policy", "url": null, "score": 0.82 }],
    "latency_ms": 1240
  },
  "low_confidence": false,
  "usage": { "tokens_in": 812, "tokens_out": 96, "latency_ms": 1240 }
}

Streaming

With stream: true the response is text/event-stream with three event types: start carries the conversation id and citations, delta carries each text fragment, and done carries the saved message.

text

event: start
data: {"conversation_id":"cm…","citations":[…]}

event: delta
data: {"text":"Annual"}

event: done
data: {"message":{…},"low_confidence":false}

Pagination

List endpoints are cursor based. Pass limit (max 100) and, to continue, the next_cursor from the previous response. has_more tells you when to stop.
