How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
Returns a JSON object with an `ok` boolean, the tool name, and a `result` object containing: `valid` (true/false), `errors` (array of objects each with `path`, `keyword`, and `message`), and `errorCount` (integer). If valid, errors array is empty and errorCount is 0.
Example use cases
API payload validation before sending
“Before I send this request payload to the orders API, can you check it against the orders schema and tell me if anything is wrong? The payload is {"orderId": -1, "customerEmail": "john@", "quantity": 5} and the schema requires orderId >= 1 and a valid email format.”
CI pipeline JSON config check
“I have a deploy config JSON I want to validate against our config schema before merging — can you run it through validation and list every error with its field path? Here's the config and schema.”
User form data integrity check
“A user just submitted a registration form and I have the data as JSON. Can you validate it against our user schema — checking formats like email and date-of-birth — and return a list of all the errors so I can show them which fields to fix?”
Technical details
Endpoint
POSThttps://x402-toolbox.swiftbotlab.workers.dev/v1/json/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, pay-per-call JSON Schema validator with no API key or account setup — ideal for ad-hoc validation in automated pipelines, agent workflows, or one-off checks. Prefer it over self-hosted validators when you want zero infrastructure overhead and are already using x402 micropayments. It supports format keyword assertion as an option, which many minimal validators skip.
Side effects
- Malformed JSON schema causes a schema-parsing error response
- Data that cannot be parsed as JSON and is not a plain string may produce unexpected results
- Invalid or unsupported JSON Schema keywords may be silently ignored or cause errors
- Payment failure via x402 results in a 402 response before validation occurs
- Very large JSON payloads may hit Cloudflare Workers size limits
