# Tanship PayAI — Browser to Markdown

> Tanship PayAI — Browser to Markdown is a paid API for AI agents from x402.tanship.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Fetches a webpage via headless browser automation and converts its content to Markdown, gated by a $0.005 USDC x402 micropayment on Base.

## 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 tanship-payai-browser-to-markdown-8359867e -d '<json body>'
```

Example prompt: Can you fetch the page at https://example.com/article and give me its content as Markdown so I can paste it into my notes?

## When to prefer this

Use this endpoint when you need to fetch a webpage that requires JavaScript execution (SPAs, React/Vue apps) and want the output in Markdown format suitable for LLM consumption. Prefer this over plain HTTP fetch tools when the target page is dynamically rendered. The $0.005 USDC per-call micropayment model via x402 makes it suitable for pay-per-use agent pipelines without subscriptions.

## Known failure modes

- Page not reachable or returns non-200 status — endpoint may return an error or empty markdown
- JavaScript-heavy SPAs with lazy loading may miss content loaded after initial render
- Payment failure or insufficient USDC balance causes a 402 response before any content is returned
- Malformed input schema (missing required fields like type, method, bodyType) results in a 400 validation error
- Anti-bot measures on the target site may block headless browser access

## How this service works

Payment-gated AI and browser automation API using the x402 protocol. All /v1/* endpoints require USDC payment on Base (eip155:8453) via x402 v2 exact scheme.

## Output

Returns the rendered webpage content as Markdown text. The browser fully executes JavaScript before extracting content, so the output reflects the page as a user would see it, including dynamically loaded sections.
