How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream YouTube API response body (JSON) is passed through directly, along with the content type header, after the $0.01 USDC x402 payment is settled. The agent receives whatever the underlying RapidAPI YouTube endpoint returns for the given path and query.
Example use cases
Fetch YouTube video details on demand
“Get me the title, description, and view count for YouTube video ID 'dQw4w9WgXcQ' — query the rapid-youtube138 endpoint at path /video/details with videoId as the parameter.”
Search YouTube for trending content
“Search YouTube for the top 5 trending music videos right now — use the rapid-youtube138 gateway at path /search with query 'trending music 2024'.”
Retrieve YouTube channel statistics
“Pull the subscriber count and total views for YouTube channel ID 'UCxxxxxx' using the rapid-youtube138 proxy at path /channel/details.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/rapid-youtube138?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need YouTube data (video metadata, search results, channel info) and want to pay per-call in USDC via the x402 protocol without managing a long-term RapidAPI subscription. It is best suited for agents operating in a web3/DeFi context where micropayment billing is preferred over API key management.
Side effects
- Insufficient USDC balance causes payment failure and request rejection
- Invalid or unsupported path results in upstream 404 or error passthrough
- Malformed query object causes upstream API to return an error
- Upstream RapidAPI YouTube service downtime results in 502/503 passthrough
- Rate limits on the upstream RapidAPI key cause 429 errors to be forwarded
