Name, symbol, decimals and total supply of any ERC20 contract in one call. Useful to label a token address before showing it to a user. Via eth_call.

Receipt of a transaction: whether it succeeded or reverted, gas used, fee actually paid, and how many logs it emitted. The call that answers did my transaction work. Via eth_getTransactionReceipt.

Screen a name in one call against US OFAC SDN, the EU Consolidated Financial Sanctions List, UK OFSI, the UN Security Council Consolidated List, and Wikidata-derived Politically Exposed Persons (PEP) data -- with fuzzy name matching, not exact-only. Real competitor research (2026-09-11) found this exact bundle+fuzzy-match shape is what actually converts in this niche; the single-source exact-match ofac-sanctions-search-v1 listing did not.

Current gas price and base fee for any supported chain, in wei and gwei, plus the cost estimate of a plain transfer. For agents planning a transaction. Via eth_gasPrice.

Retrieve one bounded day from a deterministic seven-day gospel, psalm-prayer, or practical-wisdom reading plan using source-labelled public-domain Bible text.

Every currently valid TLS certificate publicly issued for one domain, read from the Certificate Transparency logs: issuer, validity window, days to expiry, revocation status and every hostname each certificate covers. It reports what was ISSUED, which is how you find certificates you did not know existed - not what the server is serving today. No API key, no account.

Registration data for one domain, read from the registry's own RDAP service through the IANA bootstrap — not scraped from port-43 whois text. Returns creation, expiry and last-change dates, age and days to expiry, registrar, EPP status codes, nameservers, DNSSEC and the abuse contact. TLDs with no RDAP server say so instead of reporting the domain as unregistered. No API key, no account.

One lighthearted developer roast aimed at a target YOU choose - javascript, python, css, git, regex, kubernetes, agile or legacy code - and at the severity you ask for. Every other roast endpoint returns something generic; this one lets a code-review agent roast the actual stack in front of it. Bilingual, seedable and repeat-free.

Cross-references a UK haulage operator's DVSA-declared licence holder name against that company's real, live Companies House officers and persons with significant control (PSC) -- flagging a mismatch, or a recent director/PSC change, the real pattern seen in distressed-acquisition cargo-theft fraud where a haulier's licence still shows the old, legitimate operator while control of the company has quietly changed hands.

Generates an illustration from a text prompt with DreamShaper 8 LCM in about 2 seconds: painterly and character art rather than photoreal. Takes a seed for a repeatable result, a negative prompt, and your own width and height. Returns a hosted image URL valid for 24 hours; add inline=true to also get the base64. You are only charged if the image is delivered. No API key, no account.

Estimates the gas a transaction would need and prices it at the current gas price, before you sign anything. Also the cheapest way to find out that a call would revert. Via eth_estimateGas.

How much of a token a spender is still allowed to move on an owner's behalf, and whether that approval is unlimited. The check to run before an approve, and the one that finds forgotten infinite approvals. Via eth_call (allowance).

Turns a Solidity signature like transfer(address,uint256) into its 4-byte function selector and its 32-byte event topic0. What you need to build calldata by hand or to filter logs.

Validates one IBAN offline: country, expected length, ISO 7064 mod-97 check digits, whether it is inside SEPA, and the account number split out. Deterministic, no network call and no third party that can go down. Built for cleaning a list of accounts one at a time.

Checks one URL without downloading the page: HTTP status, the full redirect chain hop by hop with the code of each, the final URL, whether it ends on HTTPS, content type and size, and the security headers the server sends. Built for going through a list of links one at a time. No API key, no account.

Search live UK/EU public procurement tenders and US federal grant opportunities in one call: UK Contracts Finder, UK Find a Tender Service, EU TED (Tenders Electronic Daily), and Grants.gov. Returns source-linked metadata only -- title, buyer/funder, deadline, value, region, category codes, and a link to the original notice -- never full tender documents, specifications, or application forms. Grants.gov is queried live per-request and is never bulk-cached or resold as a stored dataset.

Runs any read-only contract call (eth_call) with your own calldata and returns the raw result, on five chains, with no API key and no rate limit. The escape hatch for anything the typed endpoints do not cover.

Discover current UK companies through the official Companies House advanced search using bounded filters for company-name inclusion, status, type, incorporation date range, location, and five-digit SIC code. Returns at most 20 normalized company-level public-register records.

Validates one EU VAT number offline: country prefix, the format that country uses, and the published check-digit algorithm where one exists. Says explicitly whether the check digits were verified or only the format. Deterministic, no network call. Built for cleaning a list of companies one at a time.

Search live macroeconomic indicators from the World Bank's World Development Indicators (WDI) database by country and indicator (e.g. GDP, population, inflation, unemployment). Restricted exclusively to WDI, source ID 2 -- the World Bank's own flagship, wholly-owned compiled dataset -- never any of the ~90 other databases the same World Bank API also serves, some of which carry third-party reuse terms. Country and indicator can be given as free text (resolved against the World Bank's own referen
