What it does
_done is pay-per-use APIs and tools built for AI agents — no accounts, no API keys, no subscriptions. An agent finds a tool, reads the metadata, pays per call in USDC via x402, gets its result, and moves on. Nine tools are live today, shipping more monthly — like a hashing/HMAC suite for real cryptographic digests LLMs can't reliably generate, and a penny-accurate mortgage amortization calculator. Bootstrapped, pay-per-use only — built for the agentic web.
Look up the network operator, country, and address block behind any IP address or ASN number. Given an internet address (IP) or a network identification number (ASN), this tool returns who operates that piece of the internet: the network number, the owner's name, the country it's registered in, the regional registry that manages it, and the exact address range it belongs to. Useful for checking where traffic is coming from, enriching security alerts, or mapping out internet infrastructure. Checks whether a website's email branding setup is correct so its logo shows up in inboxes. Checks one or more domains to see whether they are set up to show a brand logo next to emails in Gmail, Apple…from underscoredone.com

x4022025 · x402.org · ▲119Hi HN – excited to announce x402, initially developed by Coinbase (YC 12) x402 lets any HTTP API charge per request without issuing API keys or storing credit cards. Buyers (humans or AI agents) keep funds in their own wallet and dynamically discover compatible endpoints, call them as usual, and automatically pay a microtransaction in USDC or other tokens to settle. 90 second demo: https://www.youtube.com/watch?v=PV-L2AfLhJg Problem: Every time we want to use a new API we have to: find the service online create a developer account, copy a secret key into env vars, pre-fund or…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
