NFT Owner Lookup: Ethereum mainnet ERC-721 owner of any token ID. Lists the NFT token ids an address holds in one ERC-721 collection on Ethereum mainnet, read from chain state at the latest block.

Wallet Report: Base balances, top tokens, USD totals for any address. Returns: a wallet snapshot on Base: the native ETH balance, nonce, whether the address is a contract, and its balances of ten major Base tokens (WETH, USDC, USDbC, DAI, cbETH, wstETH, cbBTC, AERO, VIRTUAL, DEGEN), with USD for ETH, WETH and dollar stablecoins. One batched read, cached 60 seconds; no other tokens, no labels.

ENS resolve on Ethereum mainnet: pass name (an ASCII .eth name) for its forward-resolved address, or address (0x + 40 hex) for its verified reverse name. One paid call, USDC on Base.

Score up to 25 company or contact records against an ideal customer profile: 0-10 fit score, qualified / review / disqualified verdict, reason label. Calibrated on 240 labelled leads: 0.879 accuracy, and no qualified lead ever disqualified or vice versa. Catches competitor name variants and subsidiaries of excluded accounts that string matching misses. Uncertainty widens the net: sparse records, unnamed contacts and low-confidence calls go to review, never to disqualified.

What is this used car worth in Ireland? - Use to value a specific car: median, mean, quartiles and range of comparable Irish listings (same make, model, fuel, transmission if given, within 1 year and 30,000 km). Returns 404 (no charge) if there are fewer than 5 comparables.

Best-value used cars in Ireland right now - Use when you want a ranked list of Irish used-car listings priced below the median of genuinely comparable cars (same make, model, fuel, transmission, within 1 year and 30,000 km). Each result includes the asking price, the market median, number of comparables and the gross margin. Best for dealers, flippers and buying agents looking for opportunities.

Irish used cars whose asking price was recently cut - Use to find motivated sellers: listings whose price dropped within the last N days, with original, previous and current price and the percentage cut. Price history is recorded by us from the first time we see a listing.

Newly listed below-market cars since a given time - Use to poll for fresh opportunities: returns deals first seen by us since a timestamp (default: last 24 hours). Call on a schedule with the previous call's time to receive only new deals.

Does service@<domain> look deliverable? Builds the service@ address for the domain you give and runs the verifier: syntax, MX presence, mail provider, disposable/free-provider flags, SPF/DMARC presence and a deliverable/risky/no verdict with the reason (mailbox existence is not probed). Fast way to find a working service contact. $0.01 per check.

Bulk spf authorizes barracuda: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.

Aggregated token metadata (CoinGecko + DefiLlama): market cap, supply, addresses across chains, recent volume.

Compare circuit durations with supplied T1/T2 values using an explicit relaxation/dephasing model. For scenario planning; not a measured device-fidelity guarantee. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Calculate squared Uhlmann fidelity and purity for two supplied single-qubit density matrices. Explicit conventions; no experimental certification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Composed token classification. Fans out to token_info, token_security, protocol_tvl and returns a single archetype (stablecoin / blue_chip / mid_cap / memecoin / wrapped / governance / unverified) plus a plain-language verdict.
