Everything Agent402 knows about one x402 seller origin, in one read: i
Everything Agent402 knows about one x402 seller origin, in one read: identity and crawl history, the catalog with the provenance of every price (live-402 or manifest, when it was read, whether it is stale or disagrees with the seller's own declaration), advertised wallets against the wallets that were actually paid (own chain evidence, inherited wallets, shared claims), settlement evidence per source (our Base leaderboard, Coinbase Bazaar, Solana SPL credits, MPP transfers), the router's own.

Live spot price (and optional 24-hour change) for one or more coins fr
Live spot price (and optional 24-hour change) for one or more coins from CoinGecko's public Simple Price endpoint. Identify coins by their CoinGecko ID slug (bitcoin, ethereum, solana, usd-coin, …). Defaults to USD; pass a `vsCurrency` to denominate in EUR, JPY, ETH, BTC, etc.
Store a piece of text for later similarity recall - a per-wallet seman
Store a piece of text for later similarity recall - a per-wallet semantic index an agent cannot host in-session. Returns an id. Prefer memory-write for structured state you will look up by exact key; this pair is for fuzzy, meaning-based retrieval. Pair with /api/memory/recall to retrieve by meaning, not exact key.

List the wallets you've granted access to your namespace, with their mode and expiry.
Persistent key-value memory scoped to the paying wallet: the x402 paym
Persistent key-value memory scoped to the paying wallet: the x402 payment is the authentication, the wallet owns the namespace. Write any JSON value (up to 64KB) under a key, with an optional TTL, or delete it; read it back on any later session with the matching read route. Use it when an agent needs state that survives the session or crosses runs without an account or API key.

Classify an IP address: version, public/private/loopback/link-local, integer form, and reverse-DNS (PTR) lookup.

Atomically write (or release) a key only if its current value equals `
Atomically write (or release) a key only if its current value equals `expected` - the coordination primitive for distributed locks and optimistic concurrency across agents. Acquire a lock: expected=null + a value + ttlSeconds. Release it: expected=<your token> with no value (deletes on match). Update safely: expected=<old>, value=<new>. Returns whether it swapped and the current value.
Describe a task (or name a slug) and the Smart Order Router resolves t
Describe a task (or name a slug) and the Smart Order Router resolves the best-matching tool and RUNS it in the same call - flat $0.05 covering any tool listed at $0.04 or less, from THIS host's catalog or any external seller in the open index - x402 sellers, or MPP sellers on Tempo (paid on your behalf over x402 or MPP, result relayed). One payment, one request, result + receipt. /api/route quotes which tier a task needs; pricier tools return a self-correcting 409 with their direct route.

Eve’s current one-line paper pick on a live Polymarket market. $0.05 USDC. A stamp is a read; it does not sit a ticket. Omit q for her current pick.
Lookup a Farcaster profile by username or FID
Lookup a Farcaster profile by username or FID. Returns FID, username, display name, bio, profile picture URL, follower/following counts, and the canonical Warpcast URL. Use to label cast authors, validate a Farcaster handle, or fetch a profile for display.
Live cross-provider x402 market sentiment
Live cross-provider x402 market sentiment. topProviders: the top x402 sellers ecosystem-wide, ranked by REAL on-chain activity (Agent402 included and flagged isSelf:true). Pick the lens with sort: 'usd' (revenue, default - whale-skewable), 'buyers' (distinct paying wallets - broadest adoption/reach), or 'calls' (raw volume). Every row carries all metrics plus callsPerBuyer (intensity), so revenue and actual ecosystem usage are both visible.
Look up the native coin balance (ETH/MATIC) plus every ERC-20 holding
