VerifyLite
Email check: validates the address format, confirms the domain exists and accepts mail (MX), and flags disposable providers, role accounts (info@, support@), and free providers. Returns deliverable_likely, risky, undeliverable, or invalid with a reason. No message is sent. Useful for cleaning sign-up lists and lead data before outreach.
workers.dev-$0.003listed
VerifyLite
Batch website safety check: the full /safe report for several URLs in one call, priced per site and cheaper than single checks. Each result has a verdict (safe, caution, unsafe), a 0-100 score, and evidence-backed flags for TLS, redirects, security headers, mixed content, insecure forms, and domain age, plus a summary count. Useful for screening every link in a search result, email, or document at once. Not charged if no site can be checked.
workers.dev-$0.024listed
VerifyLite
Current time from a reliable server clock: UTC ISO timestamp, Unix seconds and milliseconds, and optionally the local date, time, weekday, and UTC offset in any IANA time zone (daylight saving handled). Useful because language models don't know the current date or time. Not charged for an unknown time zone.
workers.dev-$0.0011listed
VerifyLite
Look up one NFT on Base by contract and token ID: ERC-721 or ERC-1155, current owner (wallet or contract), collection name and symbol, and its metadata: name, description, image link, animation, traits. Reads ipfs://, ar://, https and inline on-chain metadata. Pass owner to confirm a wallet holds it (and its ERC-1155 balance). Read-only. Not charged for invalid input, tokens that don't exist, or when Base can't be reached.
workers.dev-$0.0056listed
VerifyLite
ERC-20 token metadata for one contract on Base mainnet: name, symbol, decimals, and total supply (human-readable and raw), with a flag for whether it behaves like an ERC-20 at all and whether it is native USDC. Handles older tokens that return bytes32 names. Useful for formatting token amounts correctly and spotting look-alike tokens. Read-only. Not charged for an invalid address or an address with no contract.
workers.dev-$0.0048listed
VerifyLite
Returns pong with the server time and an optional echo string, after a real x402 USDC payment on Base. Useful for testing that an agent's x402 payment client, wallet, and budget limits work end to end before using costlier services, and for monitoring. The cheapest paid call VerifyLite offers.
workers.dev-$0.001listed
VerifyLite
Call any read-only (view/pure) function on a Base contract and get the decoded answer. Give the function as a signature like balanceOf(address) returns (uint256) plus args, or raw 0x calldata. Supports address, bool, uint/int, bytesN, string, bytes and arrays, an optional historical block, and plain revert reasons. Raw return data is always included. Not charged for invalid input, reverted calls, or when Base can't be reached.
workers.dev-$0.0043listed
VerifyLite
Inspects one Base mainnet address: whether it holds contract code and how large, whether it is an EIP-1967 upgradeable proxy (and its implementation address), EIP-7702 delegation, and which standards it reports or behaves like (ERC-165, ERC-721 NFT, ERC-1155, ERC-20). Useful for knowing what kind of contract an agent is about to interact with or approve. Read-only. Not charged for an invalid address or when Base can't be reached.
workers.dev-$0.0046listed
VerifyLite
Current Base mainnet gas: gas price, base fee, and priority fee in gwei, plus estimated execution cost in ETH for an ETH transfer, a USDC transfer, and a typical swap, from the latest block. Useful for timing transactions and budgeting fees before sending. No input needed. Not charged when Base can't be reached.
workers.dev-$0.0015listed
VerifyLite
RSS and Atom reader: give a feed URL or any news site, blog, or podcast page and get its latest items as clean JSON: title, link, published date, author, a plain-text summary, and media (podcast audio) links. Finds the feed automatically from the page when needed. Useful for news monitoring, research digests, and tracking competitors or releases. Not charged if no feed is found or it can't be fetched.
workers.dev-$0.0038listed
VerifyLite
Current prices in USD from Chainlink Data Feeds on Base mainnet: ETH, BTC, cbBTC, SOL, USDC, DAI, and EUR. One pair or all at once, each with the feed's last update time, age in seconds, and a stale flag, read straight from the oracle contracts (the same prices DeFi protocols use). Useful for valuing balances, converting USDC amounts, and checking a stablecoin peg. Not charged for an unknown pair or when the feeds can't be read.
workers.dev-$0.0029listed
VerifyLite
Web page reader: fetches one URL and returns its main content as clean markdown with the page title, description, language, and word count. Strips navigation, footers, scripts, and styles; links become absolute markdown links. Useful for feeding web pages to an LLM, summarizing articles, or extracting text for research. Not charged if the page can't be fetched or isn't text.
workers.dev-$0.006listed
VerifyLite
Generates standards-compliant UUIDs from a cryptographic random source: version 4 (random) or version 7 (time-ordered, sorts by creation time, good for database keys), one or up to 100 per call. Useful for idempotency keys, record IDs, and correlation IDs. Not charged for invalid options.
workers.dev-$0.0012listed
VerifyLite
The largest holders of an ERC-20 token on Base, ranked, with balance, percent of supply and wallet/contract/burn type, read straight from the chain. Top 1/5/10 concentration (burns excluded), a wallets-only share, burned percent and a low-to-very-high level. For tokens whose whole transfer history fits (most new and small tokens) the list and holder count are exact; otherwise coverage is reported. Not charged for invalid input.
workers.dev-$0.0051listed
VerifyLite
Base mainnet transaction lookup by hash: status (success, failed, or pending), block, timestamp, confirmations, from, to, ETH value, total fee including the L1 data fee, method id, and every USDC transfer in the transaction decoded to sender, recipient, and amount. Useful for confirming that a USDC or x402 payment really settled before delivering goods. Read-only. Not charged for an invalid hash, a hash not found on Base, or when Base can't be reached.
workers.dev-$0.0055listed
VerifyLite
Cryptographically secure, unbiased randomness: whole numbers between min and max (default 1 to 100), or random picks from a list of choices, one or up to 100 per call. Useful because language models are bad at being random: fair draws, sampling, shuffling decisions, and A/B assignment. Not charged for invalid options.
workers.dev-$0.0013listed
VerifyLite
Speech-to-text for one audio or video file by URL, using Whisper (turbo) on a GPU. Returns the full transcript, timed segments, ready-made SRT and WebVTT captions, and the detected language; optional translation to English. Files up to 25 MB (about 25 minutes of typical MP3). Useful for captioning videos, indexing podcasts, or reading meetings. Not charged if the file can't be fetched or transcribed.

workers.dev-$0.0053listed
VerifyLite
Honeypot and sell-tax check for a Base token. Finds its deepest WETH or USDC pool (Uniswap V2/V3, Aerodrome, Slipstream) and simulates a buy then a sell on a Base node: no money moves. Returns whether selling works, the actual buy tax and sell tax, round-trip loss, pool and liquidity, with a verdict: clean, taxed, high_tax, honeypot, no_liquidity or inconclusive. Useful before an agent buys, swaps or accepts a token. Not charged for invalid input or tokens with no WETH or USDC pool.
workers.dev-$0.0085listed
VerifyLite
SEO check for one page: whether search engines can index it (meta robots, X-Robots-Tag, robots.txt rules), title and meta description length, canonical URL, H1 headings, viewport, language, Open Graph tags, sitemap, HTTPS, and redirects, with a 0-100 score and a list of issues by severity. Useful for site audits and pre-launch checks. Not charged if the page can't be fetched.
workers.dev-$0.004listed
VerifyLite
Recent token transfers for one Base wallet, incoming and outgoing, newest first: token, symbol, amount, sender, recipient, transaction hash, block and time, with likely spam airdrops flagged.

Useful for checking a counterparty's activity, confirming deposits, reconciling payments, or watching an agent's wallet. Read-only. Not charged for invalid input or when Base can't be reached.
workers.dev-$0.0047listed
VerifyLite
One-call due diligence for a Base token before buying, accepting or listing it: owner powers in the contract (mint, pause, blacklist, fees, proxy), who holds the supply (top wallets, concentration), whether it can actually be sold and its real buy/sell tax (simulated), and whether the token or its owner is on the OFAC sanctions list or a scam blacklist. Returns one verdict (ok, caution, avoid, known issuer), a 0-100 risk score and plain reasons. Not charged for invalid input.
