## 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 agentreader-credits-purchase-d0d09e96 -d '<json body>'
```

Example prompt: Buy me 500 AgentReader credits so I can start converting web pages and PDFs to Markdown — pay with USDC.

## When to prefer this

Use this endpoint when an agent or developer needs to fund an AgentReader account before making web-page or PDF extraction calls. This is the required first step if the free tier is exhausted or an API key is needed. Choose the 500-credit bundle for light or trial usage and the 5000-credit bundle for high-volume pipelines. Prefer this over alternatives when you specifically need USDC-based crypto payments via x402 and want programmatic, on-chain verifiable credit purchases.

## Known failure modes

- Invalid bundle value (not 500 or 5000) — returns validation error
- Insufficient USDC balance or failed x402 payment — returns payment error
- Malformed or missing x402 payment header — returns 402 Payment Required
- Network or blockchain transaction failure — returns error with no credits added
- Rate limiting or account issues — returns 4xx error

## How this service works

REST API and MCP server that turns web pages, JS apps and PDFs into clean Markdown or structured JSON. Free tier, then USDC pay-per-use via x402.

## Output

Returns a JSON object confirming the purchase: ok flag (true), number of credits added, the API key (ar_...) to use for subsequent extraction calls, updated total credits balance, and the on-chain transaction hash for the USDC payment.
