JSON Root Type API for agents
JSON root type and size. Use as a cheap preflight before heavier JSON processing. Returns root type (object/array/…) and a size signal. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
