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 result field containing the CSV-formatted output of the input JSON, along with a meta object providing additional response metadata.
Example use cases
Example prompt
“Convert this JSON array to CSV format: '[{"date":"2024-01-01","cashflow":-1000},{"date":"2024-06-01","cashflow":1200}]'”
Technical details
Endpoint
POSThttps://finmath.qzqh5rrbkz.workers.dev/v1/json_to_csv?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert a JSON string into CSV format within the finmath workflow, particularly when you want to export or display financial calculation results (e.g., NPV, IRR, bond cashflows, DeFi metrics) in a tabular, spreadsheet-compatible format. Prefer this over generic CSV converters when your data is already in the finmath ecosystem.
Side effects
- Invalid or malformed JSON string returns an error
- Empty JSON input may produce empty or malformed CSV
- Deeply nested JSON objects may not flatten cleanly into CSV rows
- Missing required 'json' field returns a validation error
