## 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 agentsvc-io-credits-top-up-5-usdc-791a0f06 -d '<json body>'
```

Example prompt: Top up my agentsvc.io credit balance with $5 USDC so I have funds available to call its scraping, screenshot, and search APIs.

## When to prefer this

Use this endpoint when an AI agent needs to pre-fund a credit wallet on agentsvc.io before making calls to its 70 per-call web services (scraping, screenshots, search, validation, conversion). Prefer this over per-call payment if the agent plans to make multiple API calls in a session and wants to avoid repeated x402 payment handshakes on each call.

## Known failure modes

- Insufficient USDC balance in paying wallet — payment fails and no credits are added
- Payment network (Base or Solana) congestion causes timeout with uncertain credit state
- Invalid or malformed POST body causes 400 error with no credit applied
- Duplicate payment submission may not be idempotent — credits could be double-counted or rejected

## How this service works

86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.

## Output

Returns a JSON object containing a session token (string) for authenticating subsequent agentsvc.io API calls, and the updated USDC credit balance (number) reflecting the $5 top-up.
