How this service works
Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
Returns a JSON object containing: valid (boolean), grade (letter A–F), score (0–100), error_count, errors (array of path + message + expected/received), warnings, findings (rule-based deductions), coerced (boolean), repaired (fixed data object or null), and is_repaired_valid (boolean or null). Failed calls due to server errors, upstream failures, or input-validation rejections are not billed.
Example use cases
API payload pre-flight check
“Before I write this order object to the database, validate it against my schema: required fields are orderId (uuid), quantity (number), and customerEmail (email). Tell me every field that's wrong or missing.”
Coerce and validate form submission
“I've got a form submission where numbers came in as strings — validate it against my schema with coercion on so '42' becomes 42, and let me know if it's valid after coercion.”
LLM-assisted schema repair
“This JSON payload has some errors but I want to know if it can be automatically repaired to satisfy my schema. Run validation with repair enabled and show me the fixed version if it passes after repair.”
Technical details
Endpoint
POSThttps://netintel-production-440c.up.railway.app/schema/validateWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call JSON schema validation service with no signup, API key, or subscription — especially useful for agents that need occasional data quality checks, form validation, or schema-guided repair without committing to a dedicated validation infrastructure. The built-in coercion, LLM-assisted repair, and simplified field-type map syntax (e.g. 'email', 'url', 'string[]') make it faster to use than raw JSON Schema validators when working with messy real-world data.
Side effects
- Invalid or missing 'data' field — returns 400 with input validation rejection, not billed
- Schema too large or data exceeds 64KB limit — rejected with validation error
- Malformed JSON string in 'data' that cannot be repaired — returns validation failure response
- Network or upstream server error — returns error, call is not billed
- Schema uses unsupported format keywords — may produce unexpected validation results
