How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a 'status' field ('ok' or error), a 'data' object containing the parsed JSON, and an 'roi_proof' object that includes a compression_ratio_pct field indicating how much the input was compressed or validated (e.g. 91.4%).
Example use cases
Pre-flight JSON sanity check
“Before I send this payload to the payments API, validate this JSON for me and make sure it's parseable: '{"amount":100,"currency":"USD","recipient":"bob@example.com"}'”
Agent output quality gate
“My AI agent just generated this JSON response — can you run it through a validator and confirm it's valid before I pass it to the next step: '{"tasks":[{"id":1,"done":false}]}'?”
Debugging malformed API response
“I got back this JSON from a third-party API and something seems off — can you validate it and tell me if there are any syntax errors: '{"status":"ok","data":{"value":null,}}'?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/json-validator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call JSON validation step inside an agent pipeline, especially when you're already using x402/USDC micropayment infrastructure on Base. It's well-suited for validating agent-generated JSON before downstream consumption, or for quick syntax checks without spinning up a local parser.
Side effects
- Malformed or non-JSON input returns an error status
- Missing required 'input' field causes a 400-level error
- Oversized JSON payloads may time out or be rejected
- Payment not settled in USDC on Base causes x402 payment required error
- Invalid query parameter type for raw_json causes schema validation failure
