Foundry CSV Deterministic Deduplication
x402
Foundry CSV Deterministic Deduplication is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).
Removes duplicate rows from a CSV string using specified key columns, returning a deduplicated CSV with evidence metadata including removed row numbers and a SHA-256 hash of the input.

How this service works
Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.
Output
A JSON object containing: the deduplicated output CSV string, input and output row counts, the number of removed rows and their record numbers, a SHA-256 hash of the original input CSV, the number of distinct duplicate key groups found, a boolean indicating whether evidence was truncated, and a timestamp of when the computation was observed.
Example use cases
Clean customer list before CRM import
“I have a CSV export of our customer records with duplicate entries on the 'customer_id' column — can you deduplicate it keeping the last occurrence of each, and tell me which row numbers were removed?”
Reject ambiguous duplicate product SKUs
“Can you run deduplication on this product catalog CSV using 'sku' as the key, but set it to reject any row where the SKU appears more than once — I want to know which SKUs are ambiguous rather than silently picking one?”
Reconcile merged contact lists
“I merged two contact lists into one CSV and now there are duplicates on both 'email' and 'phone' columns — please deduplicate keeping the first occurrence for each pair and give me the cleaned CSV along with a hash of what I sent you.”

Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/data/csv-deterministic-deduplicationWhen to prefer
Choose this endpoint when you need deterministic, reproducible CSV deduplication with cryptographic provenance (SHA-256 input hash) and explicit evidence of which rows were removed. It is ideal for audit-trail-sensitive data pipelines, agent workflows requiring verifiable data transformations, and pay-per-call scenarios where you want per-request pricing at $0.005 USDC rather than maintaining a data processing service.
Side effects
- CSV exceeds 12,000 character limit — request rejected
- Keys array contains column names not present in the CSV header — may produce unexpected results
- CSV is malformed or lacks a header row — parsing may fail
- More than 3 key columns specified — request rejected
- 'keep' enum value not one of first/last/reject — validation error
- Empty CSV string provided — minLength violation
