TaskMint Data Check – Record Validation Service is a paid API for AI agents from taskmint-sign-proof-node22-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Validates a batch of flat scalar records against user-defined type and range rules, returning per-field issues and a summary of data quality problems.

How this service works

Exact native USDC on Base; externally owned wallets only. Generate a private 32-byte random request_token for each new job, persist the entire body, and reuse it for challenge/retry and recovery. The token grants result access. Do not log or share it. HTTP 202 or an uncertain transport failure requires recovery with the identical body without a signature, never a new purchase. Results expire after 24 hours. Ten bounded deterministic services. Local execution is free; hosted jobs require customer-authorized payment only when billable.

Output

A JSON object indicating whether all records are valid (boolean), a list of issues each with a code (e.g. type_mismatch, below_minimum), the affected field name, record index, and expected value; plus a human-readable summary and a diagnostic scope note clarifying the service only validates flat scalar fields — not a full JSON Schema validator.

Example use cases

Pre-pipeline data quality gate

“Before I load these 30 rows into the database, check them against my rules: 'quantity' should be an integer between 0 and 10000, 'unit_price' a number above 0, and 'active' a boolean — flag anything that doesn't match.”

Catch type errors in user-submitted forms

“I've got a batch of 20 form submissions and I want to validate them — 'age' must be an integer between 18 and 120, 'email_confirmed' must be boolean and required, and 'score' must be a number. Tell me which records have issues and what's wrong.”

Audit inventory export for range violations

“Check these 45 inventory records for me: 'reorder_level' should be a number with min 1 and max 500, 'sku' must be a required string, and 'discontinued' must be boolean. Give me a summary of any violations.”

Endpoint

When to prefer

Choose this endpoint when you need lightweight, deterministic validation of flat scalar record batches (up to 50 records, up to 20 fields) against explicit type and range rules — particularly when you want per-record, per-field issue codes rather than just a pass/fail. It is not a full JSON Schema validator and does not coerce or verify data sources, so prefer it for quick diagnostic sweeps rather than complex nested schema validation.

Side effects

Payment not received or insufficient USDC — job not processed
request_token not a valid 64-char lowercase hex string — request rejected
records array empty or exceeds 50 items — schema validation error
rules object has fewer than 1 or more than 20 properties — rejected
Transport failure or HTTP 202 received — must retry with identical body and token, never resubmit with a new token
Results expired after 24 hours — result no longer retrievable
Non-EOA wallet used for payment — payment not accepted

request_token	string	Generate 32 cryptographically random bytes as lowercase hex for each new job. Keep this private result credential and reuse the identical body for retries. Replace the synthetic example token.
