How this service works
Deterministic finance and crypto math for AI agents: TradFi (NPV, IRR, XIRR, Black-Scholes + Greeks, bonds, VaR, Sharpe) and DeFi (impermanent loss, perp liquidation, funding, Uniswap v3, health factor, cost basis). Exact, model-free arithmetic that LLMs get wrong — priced per call in USDC.
Output
Returns a JSON object with a 'result' field containing the parsed CSV as a JSON array (with objects keyed by header names if headers=true, or arrays of values if headers=false), plus a 'meta' object with processing metadata such as row count and column info.
Example use cases
Example prompt
“Can you convert this CSV data into JSON for me? The first row contains headers: 'date,price,volume\n2024-01-01,150.25,10000\n2024-01-02,152.00,12000'”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/csv_to_jsonWhen to prefer
Use this endpoint when you need a lightweight, deterministic CSV-to-JSON conversion as part of a financial data pipeline on the finmath platform, especially when you need the output to feed into other finmath calculations (NPV, IRR, Black-Scholes, etc.) that expect structured JSON input. Prefer this over general-purpose parsing libraries when working within a USDC-metered agent workflow that already uses finmath services.
Side effects
- Malformed CSV string causes parse error — returns error in result field
- Missing required 'csv' field returns a 400-style error
- Empty CSV string may return empty result array
- CSV with inconsistent column counts may produce ragged arrays or errors
- Very large CSV strings may hit payload limits on the Workers runtime
