The company published the exact commits it ran and noted that a wallet's first call to its brief endpoint is free, with subsequent calls priced at $0.01.", "body_md": "I run Blockchain IQ. We sell some crypto data to software agents per request over x402 (HTTP 402, USDC on Base, no account or API key). In October we paid for integrations: 22 were submitted and we checked each one by matching its on-chain payment to our purchase log and running it in a clean temporary folder with a throwaway wallet. Twenty passed; the post lists all of them with the exact commits we ran. To try the API: `curl -i [https://www.blockchainiq.co/api/x402/v1/brief](https://www.blockchainiq.co/api/x402/v1/brief)` returns the 402 with the price ($0.01), and a wallet's first call is free. Questions about how we checked the code or what failed are welcome.\n\nComments URL: [https://news.ycombinator.com/item?id=50276639](https://news.ycombinator.com/item?id=50276639)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-x402-integrations-for-an-ai-agent-data-api-checked-in-a-clean-room", "canonical_source": "https://www.blockchainiq.co/blog/x402-integrations-from-the-build-bounty", "published_at": "2026-10-28 16:50:10+00:00", "updated_at": "2026-10-28 17:13:20.645441+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-tools"], "entities": ["Blockchain IQ", "x402", "Base", "USDC"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-x402-integrations-for-an-ai-agent-data-api-checked-in-a-clean-room", "markdown": "https://wpnews.pro/news/show-hn-x402-integrations-for-an-ai-agent-data-api-checked-in-a-clean-room.md", "text": "https://wpnews.pro/news/show-hn-x402-integrations-for-an-ai-agent-data-api-checked-in-a-clean-room.txt", "jsonld": "https://wpnews.pro/news/show-hn-x402-integrations-for-an-ai-agent-data-api-checked-in-a-clean-room.jsonld"}}
