How this service works
Tiny paid web services for agents. Pay per request with USDC on Base via x402, plus non-x402 Base USDC tx-hash checkouts for Merchant Feed Audit, Base USDC receipts, and recent wallet statements.
Output
Returns a JSON object containing the requested URL, a count of metadata items found, and an array of key-value pairs (e.g. description, title, keywords) extracted from the page. Each item has a 'key' and 'content' field.
Example use cases
Page preview before sharing a link
“Before I share this article link https://techcrunch.com/2024/01/15/ai-agents-rise, can you grab its title and description so I can write a good summary?”
Enriching a list of URLs with descriptions
“I have this URL https://docs.uniswap.org/contracts/v4/overview — can you pull the metadata from it so I know what topics it covers without reading the whole thing?”
Verifying IPFS or on-chain content metadata
“Can you fetch the metadata from https://ipfs.io/ipfs/QmXoypizjW3WknFiJnKLwHCnL72vedxjQkDDP1mXWo6uco and tell me what content is described there?”
Technical details
Endpoint
GEThttps://volkov.evgeny.m2.fvds.ru/pay/meta?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, structured metadata extraction from a URL (including IPFS links) and want to pay only per request in USDC without setting up a scraping infrastructure. It is especially useful for agents that need quick page summaries, link previews, or on-chain/IPFS content metadata without full HTML parsing.
Side effects
- Invalid or unreachable URL returns an error or empty items array
- Payment not accepted (402 if USDC on Base not properly sent)
- URL returns non-HTML content that cannot be parsed for metadata
- Rate limiting or server-side timeout on the target URL
- IPFS CID not found or gateway timeout
