Validate LLM-generated outputs against a specified JSON Schema to ensure structural correctness.

  • Verify LLM responses conform to expected data structures
  • Validate API payloads before downstream processing
  • Enforce schema compliance in automated content pipelines

Ideal buyer

LLM output pipelines and data validation agents requiring low-cost schema verification.

Use with AXON

Run this through your governed agent wallet.

  1. 01
    Bootstrap AXON once with npx @axon402/init.
  2. 02
    Use the AXON runtime MCP tools to search_x402_services or inspect_x402_offer for this service.
  3. 03
    Quote, test-buy, then run the governed paid fetch through AXON.

Send this

Prompt for your agent

A natural-language instruction for your LLM agent — with this endpoint exposed as a tool — to call this resource. Not sent to the endpoint; the endpoint consumes the JSON body below.

Pasting this prompt into a raw ChatGPT or unconfigured agent will notexecute the paid endpoint flow. Run it through an agent with the AXON runtime / MCP tools exposed (see “Use with AXON” above) so the 402 challenge, quote, and governed fetch are handled for you.

“Validate this LLM response against my user profile schema: {"name": "Alice", "age": 30}”

Endpoint request body

The JSON payload your agent sends to the endpoint.

application/json
{
  "schema": {
    "type": "object",
    "required": [
      "name",
      "age"
    ],
    "properties": {
      "age": {
        "type": "number"
      },
      "name": {
        "type": "string"
      }
    }
  },
  "response": "{\"name\": \"Alice\", \"age\": 30}"
}

Advanced HTTP details

For integrators who need the raw protocol surface. Most agents should use AXON above instead of calling these directly.

curl fallback

curl https://schemagate.melis.ai/validate-schema \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: [signed_payment_envelope]" \
  -d '{"schema":{"type":"object","required":["name","age"],"properties":{"age":{"type":"number"},"name":{"type":"string"}}},"response":"{\"name\": \"Alice\", \"age\": 30}"}'

Payment & settlement details

Raw on-chain settlement parameters. AXON above handles these automatically through quote / test-buy / governed fetch.
