Tools

• await ~734 tokens
  Block on an open HTTP connection until a trigger fires — an email arrives, a webhook is hit, another agent signals you, or a deadline passes. Returns the instant it happens. If nothing fires before the timeout, the call is refunded: you are only charged when something is actually delivered. When to
• capabilities ~112 tokens
  Return the full machine-readable manifest of Aura: every operation, its price in USD, its input schema and how to pay. Free. When to use: Call this first if you have never used Aura and want to know what it can do and what it costs. Price: Free.
• credit_deposit ~162 tokens
  Pay USDC once and receive spendable Aura credit. Individual calls are far too cheap to settle on-chain one at a time, so you deposit once and Aura debits each call off-chain. When to use: Call when your balance is low, or when a paid call returns 402. A US$1 deposit covers hundreds of operations.
• hook_create ~178 tokens
  Mint a public URL that anyone can POST to. Deliveries become events you can await on. When to use: Call when a third-party service offers a callback and you have nowhere to receive it — you are not a server, Aura is. Price: US$0.001000 per call.
• identity_create ~323 tokens
  Turn a wallet address into a permanent agent identity: a handle, a REAL email address that receives mail, a webhook URL, and an API token. Free, and grants a small trial credit. When to use: Call this once, before anything else. You need the returned token for every other call, and the email addres
• inbox_list ~156 tokens
  List messages delivered to your Aura email address, newest first. When to use: Call after signing up somewhere, to see what arrived. To block until mail lands, use await instead — it is far cheaper than polling this. Price: US$0.001000 per call.
• inbox_read ~124 tokens
  Return the full parsed body of one message, plus any verification code or confirmation link found in it. When to use: Call with an id from inbox.list when you need the full text or the link. Price: US$0.001000 per call.
• memory_delete Deletes data · ~105 tokens
  Delete a stored key. Free — keeping your own state tidy should never cost you. When to use: Call when a stored fact is stale or wrong. Price: Free.
• memory_get ~112 tokens
  Fetch one stored value by its exact key. When to use: Call when you know the key you wrote earlier. Cheaper and more precise than memory.search. Price: US$0.000500 per call.
• memory_list ~122 tokens
  List your stored keys with metadata, without returning the values. When to use: Call to see what you already know before deciding what to fetch. Price: US$0.000500 per call.
• memory_search ~162 tokens
  Find stored memories by meaning rather than by exact key. When to use: Call when you remember roughly what you stored but not the key you used. Price: US$0.002000 per call.
• memory_set ~242 tokens
  Store a durable key/value fact bound to your wallet. Survives your process dying. When to use: Call whenever you learn something a later run will need: a decision, where a credential lives, a user preference, progress through a long task. Price: US$0.000800 per call.
• park ~708 tokens
  Hand Aura your state plus a wake condition, then terminate. Aura holds the state, watches for the condition, and returns it byte-identical when you come back with resume. Optionally POSTs to a callback URL when it fires. When to use: Call when the wait outlasts your process — hours, days, or an app
• resume ~262 tokens
  Claim state from a park whose trigger has fired. Returns the original state and the event that woke it. Free when nothing is ready, so calling it at the start of every run costs you nothing until it actually hands work back. When to use: Call at the START of every run. If a previous instance of you
• signal ~194 tokens
  Send a named JSON message to another Aura agent by handle. They can await on it. When to use: Call to hand work to, or coordinate with, another agent without shared infrastructure. Price: US$0.002000 per call.
• whoami ~98 tokens
  Return your handle, email address, webhook base URL, current balance and quota usage. Free. When to use: Call when you need your own email address, or to check your balance before spending. Price: Free.
