🆕 B20 adds memos to transfers/mints/burns (transferWithMemo) for payment IDs, compliance tags and settlement correlation — a field ERC-20 has no equivalent for. Reads a token's on-chain Memo event history, optionally filtered by a specific memo (bytes32) or the caller wallet. The settlement-reconciliation primitive for agents paying over B20 stablecoins.

Agents are the easiest MEV prey: predictable, public-mempool, a measured ~$50M/quarter tax. A sandwich only pays when a trade moves the pool enough to front-run (size vs pool depth). This returns an exposure read (low/elevated/high) and a protected-execution plan: a tight min-out, private/off-mempool inclusion (a Cobalt validity tx via validity-build), and splitting a large order into unattackable chunks. Pass tokenOut + amountUsd. Not financial advice.

Surfaces the LP holders, how much of the LP supply is locked or burned vs pullable, the lockers, and unlock dates. Unlocked liquidity is the clearest rug setup — this shows the detail a one-line 'LP locked: yes/no' hides.

Pay once to register a price-threshold alert on any Base token. Supply target price, direction (above/below), and an https webhook URL. A cron checks DexScreener every 10 minutes and POSTs your webhook when it crosses — HMAC-signed (secret returned once at registration), retried up to 3 times. Expires after 30 days. Or omit the webhook and poll with check=<id>: the verdict is THRESHOLD_MET, ok, FIRED, or unknown when the price feed could not be read.

🆕 A B20 Stablecoin's currency() is SELF-DECLARED — the standard verifies nothing. This is the missing check: declared peg vs actual DEX market price. 'Says USD, trades at $0.71' in one call: on_peg / depeg_warning / depegged / no_market (the peg is a pure claim with zero price discovery) / unverifiable_fx for non-USD pegs. Run before settling in any B20 stablecoin.

The payer-trust mirror of x402-seller-check. Reads a wallet's outgoing USDC payments on Base over 90 days: distinct sellers paid (breadth), total payments and USDC (depth), and whether it ever paid the same payee twice. Breadth with no depth in a short burst is the crawler/sampler pattern; a repeat or sustained payer is the opposite. Sees only Base USDC; absence reads as 'thin', never bad. Not financial advice.

Recent history of a NEAR account, summed up: transactions signed and received, failures, NEAR sent and received, token flows in and out per token, the contracts it calls most, who it deals with most, and signals (inactive, failing, receive-only). One-line summary plus the last 10 transactions. Reads the NearBlocks indexer; limit sets how many recent transactions (default 25).

Health factor of an account's Rhea Lending (Burrow) position on NEAR, computed as the contract does — collateral discounted and debt marked up by each asset's volatility ratio — with collateral and debt in USD, how far collateral can fall before liquidation, and GO / HOLD / STOP. Positions from the contract, prices from NEAR Intents.

Compress up to 16K characters of anything — articles, transcripts, email threads, reports — into 3-5 precise bullet points, one micro-payment per call. No API key, no subscription, no prompt engineering: send text=, get bullets back as clean JSON. The digest step for agent pipelines that read more than they can carry in context.

Before an agent takes a NEP-141 token on NEAR: who can change it? Counts full-access keys that can redeploy the contract, and asks the contract for an owner and a pause switch — issued tokens like USDt keep control through owner methods, not keys. No key and no owner → GO; key- or owner-controlled → HOLD; paused, no contract or not NEP-141 → STOP. Plus name, symbol, supply, and NEAR Intents liquidity and price. Live from the NEAR RPC.

Net worth of a NEAR account: its NEAR (liquid and staked) plus balances in every NEP-141 token NEAR Intents routes with a live price — USDC, USDT, wNEAR, bridged BTC and ETH and more — each valued in USD and sorted by value, with the total. Says how many tokens were scanned; tokens outside that list are not included. Live from the NEAR RPC, priced by NEAR Intents.

Choosing between spot and a perp? This is the data that choice needs. Aggregate OI-weighted perpetual funding, open interest and basis for a coin across venues (CoinGecko, no key): who pays whom (longs crowded vs shorts crowded), the carry you earn or bleed holding the perp, and contango vs backwardation. Verdict neutral / elevated / extreme. Pass symbol=BTC. Funding annualised as an estimate (8h intervals assumed). A market-structure signal, not a price call. Not financial advice.

The NEAR counterpart of agent-pay-gate. Composes the recipient's account posture (does it exist, is it a contract, control flags) with the NEP-141 transfer preflight into one GO/HOLD/STOP before an agent sends. On NEAR a mistyped account is unrecoverable and a token transfer silently fails unless the recipient has storage_deposit — this catches both ahead of time. Pass token (+amount) for a token transfer, near= for native-amount sizing. Not financial advice.

Top holders of a NEP-141 token on NEAR with each one's share of total supply, labelled as the token itself, an issuer treasury, a contract (pool, bridge, custodian) or a plain account, so neither a pool nor unissued stock is mistaken for a whale. Holder count, shares, and LOW / MEDIUM / HIGH concentration of plain accounts over circulating supply. Supply from the NEAR RPC, holders from NearBlocks.

🆕 B20 Asset tokens can post on-chain announcements (Announcement: id, description, uri) — issuer notices, corporate actions, redemptions — a channel ERC-20 has no equivalent for. Reads a token's announcement feed (active vs ended) from CDP-indexed events. The issuer-communications primitive for agents holding tokenized/RWA B20 assets.

Give a token and a trade size in USD → the deepest Base pool to route through, estimated price impact, a suggested slippage tolerance + minimum-out, all gated on a honeypot/sell-tax check of the token you'd receive (no point routing into something you can't sell). Moves an agent from analysis to action in one call.

Scans the whole perpetual market and ranks the most crowded longs and shorts by funding, so an agent finds squeeze / mean-reversion setups in one call. Extreme positive funding = crowded long (long-squeeze risk on a dip); extreme negative = crowded short (short-squeeze fuel on a pump). Returns the market tilt plus the top coins at each edge, OI-weighted over a liquidity floor. CoinGecko, no key. A setup radar, not an entry signal. Not financial advice.

The B20-only rug vector: a token can launch clean and later attach a sender blocklist (PolicyUpdated) — silently becoming seizable via burnBlocked. This reads the token's full policy/pause event timeline (CDP-indexed onchain events) plus the live policy state, and tells you if — and exactly WHEN — it turned seizable.

Measured APY of NEAR liquid staking (LiNEAR, Meta Pool stNEAR): each token's redemption price in NEAR now against N days ago from an archival node, annualised — no advertised rates. Plus NEAR staked behind each, and the cost of exiting instantly by selling for wNEAR through NEAR Intents instead of waiting ~2–3 days to unstake. days sets the window (default 7), size the exit in USD.

The flagship report: aggregates token risk, holder concentration, price/liquidity and OFAC sanctions, then AI synthesizes a structured verdict (avoid → favorable) with key risks and positives. One call, agent-ready intelligence you can't get free.
