402utils.com
402utils.com is a general-purpose utility host targeting agents and developers who need lightweight, stateless data transformation without standing up their own conversion infrastructure. It covers four practical conversion tasks (JSON↔CSV, HTML→Markdown, datetime timezone shifting) plus one diagnostic tool for verifying x402 payment plumbing. It does not offer storage, retrieval, or computation beyond these conversions.
Capabilities
Tabular Data Conversion
Converts between JSON arrays of objects and CSV text in both directions, supporting delimiter options, nested-field flattening, header handling, and parse-error recovery.
convert-json-to-csvconvert-csv-to-json
Document Format Conversion
Transforms raw HTML documents or fragments into clean GitHub-Flavored Markdown, optionally extracting the main article content via Readability.
convert-html-to-markdown
Datetime Conversion
Converts a single datetime string between any two IANA time zones with correct DST handling and UTC offset resolution.
convert-timezone-datetime
Integration Testing
Echoes an arbitrary JSON payload back with a server timestamp, allowing agents to verify that x402 payment flow and HTTP plumbing are functioning correctly.

Workflows
CSV Round-Trip Validation
Use when an agent needs to verify that a CSV dataset survives a full parse-and-reserialize cycle without data loss or structural changes.
- 1convert-csv-to-jsonParse the original CSV into a structured JSON array of objects, capturing headers and any parse errors.
- 2convert-json-to-csvRe-serialize the JSON array back to CSV using the same delimiter, then compare output against the original to detect drift.
Web Content Ingestion Pipeline
Use when an agent needs to fetch HTML from an external source, convert it to Markdown for LLM consumption, and then store or transmit the result as structured tabular data.
- 1convert-html-to-markdownConvert the retrieved HTML document into clean Markdown, optionally isolating the main article body.
- 2convert-json-to-csvIf the downstream system requires tabular output, serialize extracted structured fields (e.g. title, excerpt, markdown body) as a CSV row.

Own 402utils.com? List it with your agent
Paste the prompt below to your coding agent. It runs a real paid test on every route, fixes what scores low, and re-auditions until they pass — the gaps below are already filled in for you.
- 23 of 32 routes have never been scored — the audition tests them for the first time.
- 1 route is scoring below 50 — likely broken, mispriced, or returning the wrong shape.
- 11 routes are flagged by the verifier as failing or inconclusive.
Paste this to your agent
Make my x402 API at https://402utils.com discoverable on x402gle. Read the instructions at https://x402gle.com/agent.md and follow them end to end. Install the OpenDexter CLI, then run `npx @dexterai/opendexter audition https://402utils.com --json`. Heads up: 23 routes have never been scored and 1 route is scoring below 50 — start there. Read the score and fixInstructions for every route, fix my OpenAPI and endpoints until each route passes, and re-audition until it does. A passing audition lists my API automatically.
