# OTel GenAI Trace Validator

> Free tool #3

Check an OpenTelemetry span against the gen_ai.* semantic conventions — what conforms, what is missing, what is deprecated.

## Three ways to use it

**Web** — the interactive page: https://telemeter.ai/tools/otel-validator

**MCP** — a `tools/call` on the public MCP server at https://telemeter.ai/mcp (tool name: `otel-validator`), read-only, no key required.

**REST** — `POST https://telemeter.ai/api/tools/otel-validator` with a JSON body matching the input schema below:

```json
{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "trace": {
      "anyOf": [
        {
          "type": "string",
          "minLength": 1
        },
        {
          "type": "object",
          "propertyNames": {
            "type": "string"
          },
          "additionalProperties": {}
        },
        {
          "type": "array",
          "items": {}
        }
      ]
    }
