`agent_readiness`Score how ready a website is for AI agents, 0-100: llms.txt, sitemap, OpenAPI spec, MCP server card, A2A agent card and x402 payment discovery, each found or missing with its URL, which AI crawlers (GPTBot, ClaudeBot, PerplexityBot and others) robots.txt lets in, and a list of fixes. Reads only the public files a site publishes; nothing is signed in or submitted. Use to audit your own site or vet a service before an agent relies on it. Example: url=https://stripe.com. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

`ai_answer`Answer a question from the live web in one call: a Brave web search, the top result pages read, and an answer written by Llama 4 Scout from those sources only, with inline [n] citations and the source list (title, URL). Says so when the sources do not answer it. Results are for the caller's immediate use only: no storing, resale or model training (Brave API terms). Use when an agent needs a current, sourced answer rather than raw search results. Example: q=What is the x402 payment protocol?.

A malformed address or slot is rejected with 400, uncharged. Example: address=0xaf88d065e77c8cC2239327C5EDb3A432268e5831.

Use to pick a product or company name, or to check a brand before launch. Availability is not a price quote: premium and reserved names exist. Example: name=agentdatatools. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.

Example: to=0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359, data=0x18160ddd. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free.

Example: text=Det här är en mening skriven på svenska om väder och resor.. Price $0.01/call via x402 USDC or a card key (/credits), first 25 free; failed calls free. Reads or computes only and changes nothing; each call is charged, so repeats are not free.
