Current Base gas: base fee, priority fee percentiles over the last 10 blocks, the L1 data fee of a typical transaction, and what an ETH transfer, an ERC-20 transfer, a USDC transferWithAuthorization (an x402 payment), a swap and an NFT mint cost now in ETH and USD (ETH/USD from Chainlink).

Extract the text of a PDF at a public URL, page by page, with its title, author and page count. Up to 10 MB; scanned PDFs without a text layer return little text.

Encode text or a URL as a QR code: PNG (base64 and a data URL) or SVG, with the size and error correction level you choose.

A, AAAA, CNAME, MX, TXT, NS, CAA and SOA records of a domain from public resolvers (Cloudflare and Google), or just the types you ask for, and whether the domain exists.

Request an https URL and report whether it is reachable, its status, every redirect hop with timings, key and security headers (HSTS, CSP and others), and the TLS certificate with its issuer, the names it covers and the days until it expires. An unreachable URL is a result too, with the reason.

Fetch a public web page and return its main content as clean Markdown (Mozilla Readability, as in Firefox Reader View, then Markdown with absolute links and tables), with title, byline, site name, published date, language, excerpt and a token estimate. Navigation, ads and footers are left out. Pages that cannot be read (errors, not HTML) are not charged.

Check a web page for changes: each call compares the page's readable text with your previous check of the same URL (kept per paying wallet for 90 days) and returns whether it changed, when you last checked, and the added and removed lines. The first call records the page. Use name to keep several watches of one URL apart.

The ETH balance and ERC-20 balances of an address on Base, for the tokens you name or a default list of well-known tokens (USDC, WETH, cbBTC, AERO, DAI, USDT, DEGEN, VIRTUAL and others), with USD values for ETH, stablecoins and up to five other held tokens priced from their pools.

The USD price of any ERC-20 on Base, read from its Uniswap v3 and Aerodrome pools against USDC and WETH (ETH/USD from Chainlink). The deepest pool sets the price; each pool's price and depth is listed, and thin markets are flagged. Accepts an address or a symbol such as ETH, USDC, cbBTC, AERO, DEGEN, VIRTUAL.

On-page SEO audit of one public page from its HTML only: title and description length, one H1, canonical link, language, viewport, robots meta, Open Graph tags, images without alt text, internal and external links, word count. Returns each check with its value and pass or fail. No Core Web Vitals, backlinks or keyword volumes.

Name, symbol, decimals and total supply of an ERC-20 token on Base, by address or well-known symbol, with its Basescan link.

Reads a site's public robots.txt (crawl rules, sitemaps, AI-crawler rules) and security.txt (RFC 9116: contact, expiry, policy), and says whether security.txt is present, current or expired. Missing files are reported as absent, not as errors.

Token safety checker API for Base (honeypot and rug check). Base ERC-20 token safety verdict: SAFE / CAUTION / DANGER, score 0-100 and the reasons, from a simulated buy-transfer-sell on the token's own pool (honeypot and tax detection), owner powers (mint, blacklist, pause, tax setters, upgradeable proxy, renounced), liquidity, LP burn, holder concentration, verified source and age.

Crypto funding rates API (perpetual futures). Perp funding rates for one asset across Hyperliquid, dYdX v4, Paradex and Aevo: per-venue funding normalized to 8h % and APR, open interest in USD, cross-venue median and OI-weighted funding, spread, cheapest venue to be long or short, and a positioning read (crowded long / long bias / neutral / short bias / crowded short). Fail-closed: failed venues are listed, never estimated. Not financial advice.

Dependency vulnerability scanner API. Dependency security scan for agents and CI: send a package.json, lockfile, requirements.txt, go.mod, Cargo.lock, poetry.lock or composer.lock (or a package list, up to 500). Returns known vulnerabilities (CVE/GHSA ids, severity, CVSS, fixed-in versions) and confirmed-malicious packages per dependency, from OSV.dev. Search intents: dependency vulnerability scan, npm audit api, sca api, lockfile security scan, cve lookup, software supply chain security.

AI agent identity verification API. Checks whether an AI agent is registered in the Concordium Agent Registry (CIS-8004), Active, and Verified by Concordium (Agent Card hash matches on-chain). Suited to agent marketplaces and payment flows that need to confirm a counterparty agent identity before trusting or paying it. Input: badge (CIS-2 token address) or Concordium account.

AI readiness website audit API. Is this website ready for AI agents? Score 0-100, grade A-F and verdict with category scores (agent access, readable content, discovery, agent interfaces, speed/HTTPS), the top 5 prioritized fixes and which AI bots robots.txt blocks. Checks robots.txt for 17 AI bots, bot challenges, raw-HTML content, markdown, llms.txt, sitemap, JSON-LD, meta/OG, OpenAPI, MCP, A2A agent card, x402, HTTPS and speed.

MCP server checker API. Preflight a public remote MCP server before connecting or paying: does it answer an MCP initialize, which protocol version, sign-in method (OAuth metadata), x402 payment terms, latency, tool count, token cost, provider compatibility, poisoning patterns in tools and instructions, and a grade with issues. Lists tools only, never calls them. Blocked or unresolvable URLs are never charged.

Offline transaction and signature safety check API for crypto wallets. Offline pre-sign check (no RPC, fast): decodes a transaction, EIP-712 typed data (Permit, Permit2, EIP-3009), an EIP-7702 authorization or an x402 402 + payment payload and returns SAFE/CAUTION/DANGER, every risk flag with its reason, decoded args, counterparties, x402 payment-vs-402 match and OFAC SDN screening. Use /v1/check for on-chain facts and simulation.

Secret and PII detection API (redact before sending to an LLM). Find and redact leaked secrets before an AI agent sends text to an LLM, tool or webhook: crypto seed phrases (BIP39 checksum), EVM/Solana private keys, WIF, xprv, API keys (GitHub, AWS, Stripe, OpenAI, Anthropic, Slack...), JWT, PEM, cards, IBAN, SSN, email, phone. Verdict, findings and redacted text.
