How this service works
$0.0002/MB. Row-level changeset between two tables — added, removed, and changed rows. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny
Output
A structured changeset object containing three collections: added rows (present in table B but not A), removed rows (present in table A but not B), and changed rows (present in both but with differing field values), billed at $0.0002/MB of input data with a 1¢ x402 minimum charge and any remainder auto-credited.
Example use cases
Audit daily database export changes
“I have two CSV exports of our customer table — one from last Monday and one from today. Can you diff them row by row and tell me which customers were added, removed, or had their data changed?”
ETL pipeline change detection
“Before loading today's product catalog into our data warehouse, diff it against yesterday's version and return only the rows that are new, deleted, or updated so I can do an incremental load.”
Reconcile two data sources
“I have the same user table from two different systems and I need to find where they disagree — can you compare them and list every row that exists in one but not the other, or where field values differ?”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/data/diffWhen to prefer
Choose this endpoint when you need a precise, row-level diff between two tabular datasets and want a structured changeset (added/removed/changed) rather than a simple hash or summary. It is ideal for ETL incremental loading, data auditing, reconciliation between two system exports, or change-data-capture workflows where you need exact row attribution. Prefer it over manual diffing scripts when operating inside an agentic pipeline that can handle x402 micropayments automatically.
Side effects
- Malformed or incompatible table schemas — rows cannot be matched if primary keys are inconsistent or missing
- Payload too large — very large tables may time out or incur high per-MB costs
- Mismatched column structures between the two tables causing comparison errors
- Invalid JSON or CSV format causing parse failure
- Insufficient x402 payment balance for data volume processed
