Ephemeral Cloud tools (6, 4 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • create_callbackwrite action

    Schedule a delayed wake ($0.01): after delay_seconds the payload lands in the resource mailbox (fetch with get_events), and is POSTed to callback_url if that URL echoes the x402_challenge query parameter. Granularity ~60s.

  • create_watchwrite action

    Delegate waiting: the service polls a public URL until a condition holds, then delivers the result to the resource mailbox (and to a challenge-verified callback_url). One-shot. $0.25 up to 24h, $1.00 up to 7 days. Far cheaper than polling with your own inference calls.

  • create_webhookwrite action

    Create a temporary inbound webhook URL you can hand to any third-party service. Incoming requests are stored; fetch them with get_events. First call per IP is free (15 min); otherwise $0.01 (≤1h TTL) or $0.05 (≤24h). Returns url, retrieve_url, read_token, delete_token.

  • delete_resourcewrite action

    Delete a webhook, callback, or watch early using its delete_token. Free.

  • get_events

    Fetch the stored events/results of a webhook, callback, or watch using its read_token. Free.

  • service_info

    Machine-readable description of the Ephemeral Cloud service: every endpoint, exact prices in USDC, limits, and error codes.
