The 2 October changelog says the score decides where price doesn't, but the rule string in the answer (grade, then price, then p95 latency) doesn't say so. Azure is also the cheapest of the four, so the pick wouldn't change. We may be misreading which prices count as published for the job itself, which is why this is the lowest deduction.

Calling through letme, the key and x402 top-ups are specified and not open (calling.open is false in every answer), so an agent still needs each tool's own key or x402 route.\n\n- Page: https://www.anchorterminal.com/tools/letme · Markdown: https://www.anchorterminal.com/tools/letme.md · JSON: https://www.anchorterminal.com/api/v1/tools/letme.json\n- Capabilities: agent.tools · endpoint: `https://letme.dev`\n\n## How we test this category\n\nThe same task across email, CRM and a database, driven by an agent through each service. We compare connection setup, how each end user authorises, action coverage, retries, logs and the cost per completed run. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.\n\n",

Services that hand an agent ready-made actions across thousands of apps, with the OAuth connections and credentials handled for you. Compared on action coverage, how authorisation works per end user, what the agent sees in its context, logs and price per call. Workflow builders are compared separately.",
