Direct API

Overview

Use this path if you’re not on Node.js, or if you need to send data the SDK doesn’t capture. The ingest endpoint accepts conversations and agent definitions in one of five formats.

Endpoint

POST https://app.calado.ai/api/ingest

Authentication

Pass your agent’s API key as a Bearer token.

Authorization: Bearer cl_your_api_key_here

Keys are prefixed with cl_ and managed from your agent’s Settings page in the dashboard.

Request format

The top-level request body:

Required

At least one of conversations or agentDefinitions must be present. Empty payloads are rejected.

Optional

string (UUID)

Pin the request to a specific agent. Validated against the API key. If omitted, the key’s default agent is used.

enum

Only set this when forwarding provider request/response bodies untouched. One of anthropic, openai_chat, openai_responses. Omit to use the default shape shown in the examples. See Format selector below.

array

Array of conversation objects. Max 1,000 per request.

array

Array of agent definition objects. Max 100 per request.

Conversation object

Required

array

required

Array of message objects. Min 1, max 10,000.

Optional

string

Your stable id for this conversation. 1-255 characters. Used to link conversations across ingest calls (for multi-turn sessions) and to deduplicate.

string

Grouping id for related conversations. Max 255 characters.

string (UUID)

Link this conversation to a specific agent definition version. Used when analyzing against a known spec.

object

Arbitrary key-value data. Surfaces in the dashboard under the conversation.

object

Structured trace information. See Trace data below.

object

Position of this conversation in a multi-agent orchestration. See Steps below.

Message object

Required

string

required

Typically user, assistant, system, or tool. Any non-empty string is accepted.

string | ContentBlock[]

required

Either a plain string (max 100 KB) or an array of content blocks (1-1,000 blocks).

Optional

string (ISO 8601)

When the message was produced. Used for ordering when multiple messages share the same logical turn.

Agent definition object

Required

string

required

Human-readable name. 1-500 characters. Combined with type to dedupe versions.

enum

required

One of system_prompt or tool_schema.

string

required

The definition text. 1 byte to 100 KB.

Content blocks

Messages support either a plain string or typed content blocks. Block types mirror Anthropic’s:

Type	Shape
`text`	`{ type: "text", text: string }`
`thinking`	`{ type: "thinking", thinking: string }`
`tool_use`	`{ type: "tool_use", id?: string, name: string, input: unknown }`
`tool_result`	`{ type: "tool_result", tool_use_id?: string, content?: string \| Array<{type:"text", text:string}>, is_error?: boolean }`
other	`{ type: string, ...anything }` — unknown block types pass through

Trace data

When you have structured trace info (tool calls with outputs, retrieval results), attach it so analysis has more to work with.

array

{ type, timestamp, duration?, metadata? }[]. Generic trace events.

array

{ name, input, output?, error?, timestamp?, duration? }[]. One entry per tool invocation.

array

{ query, chunks[], sourceDocIds?, timestamp? }[]. RAG retrieval results.

Steps

When a conversation is one call inside a multi-agent orchestration, attach a step so calado can render the run as a tree and attribute behavior to the right sub-agent. Omit it for single-agent conversations.

string

Stable id for this step within the run.

string

Id of the parent step. Omit for the root step. Cannot equal step.id.

string

Human-readable role for this sub-agent, e.g. orchestrator or flight_search.

string | object

The sub-agent’s dynamic prompt or tool schema for this call — the “how it should work” side calado analyzes this step against. String or object, up to 100 KB. Omit it and the step is analyzed against the agent’s static definition.

Format selector

The format field tells calado how to parse the conversations array when you’re forwarding provider bodies untouched. Omit it to use the default shape shown in the examples.

Value	When to use
`anthropic`	You’re forwarding Anthropic `messages.create` request/response bodies untouched.
`openai_chat`	You’re forwarding OpenAI `chat.completions` request/response bodies.
`openai_responses`	You’re using OpenAI’s newer `responses.create` API.

If you’re forwarding provider-shaped data, set format explicitly. Otherwise, leave it off and use the shape shown in the examples.

Example

curl -X POST https://app.calado.ai/api/ingest \
  -H "Authorization: Bearer $CALADO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "conversations": [
      {
        "externalId": "session_abc123",
        "messages": [
          { "role": "user", "content": "What is the refund window?" },
          { "role": "assistant", "content": "You can request a full refund within 30 days." }
        ]
      }
    ],
    "agentDefinitions": [
      {
        "name": "system",
        "type": "system_prompt",
        "content": "You are a customer support agent for Acme Corp."
      }
    ]
  }'

Response

Success (202 Accepted)

{
  "conversations": {
    "accepted": 12,
    "skipped": 0,
    "failed": 0
  },
  "agentDefinitions": {
    "created": 1,
    "unchanged": 2
  },
  "warnings": []
}

Field	Meaning
`conversations.accepted`	Stored with `pending` classification. Analysis runs when you click Run Analysis in the dashboard.
`conversations.skipped`	Rejected for structural reasons (see `warnings`).
`conversations.failed`	Stored, but analysis will not run.
`agentDefinitions.created`	New definitions stored (content hash changed or new).
`agentDefinitions.unchanged`	Content hash matched an existing version.
`warnings`	Non-fatal per-item messages.

Error

Code	Meaning
`400 Bad Request`	Payload failed schema validation. Body contains Zod error details.
`401 Unauthorized`	Missing, malformed, or invalid API key.
`403 Forbidden`	Key exists but doesn’t have access to the specified `agentId`.
`413 Payload Too Large`	Request body exceeds 5 MB.
`429 Too Many Requests`	Rate limited. Back off and retry.
`5xx`	Server error. Safe to retry with exponential backoff.

Batch limits

Limit	Value
Request body size	5 MB
Conversations per request	1,000
Agent definitions per request	100
Combined conversations + agent definitions	1,000
Messages per conversation	10,000
Content blocks per message	1,000
Message content	1 MB
Agent definition `content`	100 KB
Tool schemas per conversation (adapter-extracted)	256

Error handling

Retry on 5xx and network errors only, with jittered exponential backoff. 4xx responses are permanent and should not be retried. On repeated 401 responses, stop retrying and surface the error to your operator. The key is wrong, and retrying won’t fix it.
