# StatementKit: Bank Statement to JSON/CSV/Ledger Converter

> StatementKit: Bank Statement to JSON/CSV/Ledger Converter is a paid API for AI agents from statementkit.zenith-ops.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-23).

Converts bank statement files (CSV, CAMT, MT940, OFX/QFX, QIF) into normalized JSON, CSV, hledger journal, or SIE4 accounting export formats.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability statementkit-bank-statement-to-json-csv-ledger-converter-bac8f6c6 -d '<json body>'
```

Example prompt: I have a CAMT.053 bank statement from my Swedish company — can you convert it to hledger format with assets:bank:seb as the asset account, income:revenue for incoming money, and expenses:costs for outgoing, using SEK as the currency?

## When to prefer this

Choose this endpoint when you need deterministic, rule-based parsing of structured bank statement file formats (CSV, CAMT, MT940, OFX/QFX, QIF) rather than AI-based extraction. It is ideal for bookkeeping automation pipelines, accounting integrations, and agent workflows that need reliable, structured transaction data without hallucination risk. Prefer it over general-purpose LLM parsing when format fidelity and auditability matter, and over manual accounting tools when you need programmatic output in hledger, SIE4, JSON, or CSV.

## Known failure modes

- Unsupported or malformed input file format returns a parse error
- PDF or scanned image input is explicitly not supported and will fail
- Ambiguous CSV column names without explicit column mapping may produce incorrect field assignments
- Missing currency when the file contains none and no fallback is provided may cause errors or empty currency fields
- Ambiguous date formats without dateFormat override may result in incorrect date parsing

## How this service works

Deterministic bank statement normalizer for AI agents and bookkeeping tools: CSV from any bank, camt.052/053/054, MT940, OFX/QFX and QIF in; normalized JSON, analysis and CSV/hledger/SIE4 export out.

## Output

Returns a JSON object containing: the converted file content as a string (in the requested format — JSON, CSV, hledger journal, or SIE4), the detected or specified format name, a filename suggestion, a content-type header value, and a warnings array listing any parsing issues or ambiguities encountered during conversion.
