# OpenVerbs Format Converter

> OpenVerbs Format Converter is a paid API for AI agents from format.openverbs.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-14).

Converts structured documents between 14 formats (JSON, YAML, XML, CSV, TOML, and more) using JSON as an intermediate hub

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 openverbs-format-converter-9b99f9c7 -d '<json body>'
```

Example prompt: Convert this YAML config string to TOML: the document is '---\nname: myapp\nport: 8080\ndebug: true', pretty-print the output with 2-space indentation.

## When to prefer this

Choose this endpoint when you need reliable, bidirectional conversion between any of 14 popular structured data formats in a single call, without standing up your own parsing pipeline. It is especially useful for agent workflows that receive data in one format (e.g. YAML from a config file) and need it in another (e.g. JSON for downstream API consumption). The pay-per-call x402 micropayment model suits sporadic or low-volume conversion tasks where running a dedicated service is overkill. Prefer this over DIY parsing when format correctness and rejection of malformed input before charging are important.

## Known failure modes

- Malformed or unparseable source document rejected with error before payment
- Source-to-target structural mismatch (e.g. nested object to CSV) rejected with error
- Unsupported format enum value rejected by schema validation
- Document exceeds 1,000,000 character limit
- Missing required fields (from, to, data) cause validation error
- XML output attempted on data with non-string keys incompatible with XML element names

## How this service works

Transcode a document between json, json5, jsonc, yaml, xml, csv, tsv, toml, ndjson, ini, env, properties, plist and querystring. Any source converts to any target through a JSON hub. Malformed input or a target that cannot represent the structure is rejected before payment.

## Output

A JSON response containing the converted document as a string in the requested target format. The output reflects any specified options like pretty-printing, indentation width, CSV header treatment, or custom XML root element name. Malformed input or structurally incompatible source-to-target combinations are rejected before any payment is charged.
