DESCRIPTION

Type inference from JSON / JSON to TypeScript / JSON to Zod / JSON to JSON Schema / JSON shape inferer / quicktype-style type generator. Paste a JSON sample (or array of samples); returns a generated type definition in your chosen format. Merges across array elements / object samples — properties present in some but not all become optional, mixed primitive types become unions. Auto-detects string formats (date-time / uuid / uri / email) for richer outputs. Pure compute, no upstream call, no API key. Ideal inside agent code-gen loops that need to consume an unfamiliar API response.

formatstringOutput format requested: typescript, zod, json-schema, or similar.
root_namestringName used for the top-level generated type or schema (e.g. Root, User).
typesstringGenerated type definition source as a string in the requested format, ready to paste into code.
inferred_shapeobjectInternal shape tree with per-field types, optionality flags, and detected string formats before rendering.
sourcestringEcho of the input JSON sample (or array) that the types were inferred from.
EXAMPLEStwo ways to call
EXAMPLE 1 · curl
curl -X POST https://x402.agentutility.ai/type-inference-from-json \
  -H 'Content-Type: application/json' \
  -d '{ }'
first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.
EXAMPLE 2 · mcp
# MCP packages on npm under
# @agentutility/mcp-*  (one per cluster)
#
# Catalog + install:
# https://mcp.agentutility.ai
#
# Or call type-inference-from-json directly over HTTP — see above.
MCP server handles payment automatically — your coding agent just calls the tool by name.
