Agent Tools

Currency exchange rates (European Central Bank reference rates) for price conversion, invoicing and travel budgets. Latest or historical by date.

IP address lookup for security triage, log analysis and fraud checks: owning network, allocation range, registry country (RDAP) and reverse DNS.

Business day calculator for SLAs, invoice due dates, shipping and legal deadlines: counts working days between two dates, skipping weekends and national public holidays (ISO country code).

Public holiday calendar for 100+ countries by year, for scheduling, payroll and delivery planning.

Link preview and unfurl data: title, description, Open Graph image, site name, canonical URL, favicon and final URL after redirects.

Gas estimate and fee quote for Base, Ethereum, Optimism, Arbitrum and Polygon: eth_estimateGas for your transaction (to, from, value, data) or a plain transfer if no 'to', current base fee, slow/standard/fast priority tips from recent blocks, max fee suggestions, L1 data fee on OP-stack chains and total cost in native coin and USD (Chainlink price). Reports reverts instead of failing. Use before signing or to budget agent transactions.

Token contract inspector for Base, Ethereum, Optimism, Arbitrum and Polygon: is it a contract, ERC20/ERC721/ERC1155 detection, name, symbol, decimals, total supply (raw and formatted), owner, and upgradeable-proxy check (EIP-1967, beacon, EIP-1167 clone, legacy zeppelinos) with implementation and admin addresses. Read live from public RPC. Use before quoting, swapping, listing or paying with a token.

Format conversion for data pipelines and publishing: CSV to JSON, JSON to CSV, HTML to markdown, markdown to HTML, HTML to plain text. JSON body {from, to, input}.

One call document parsing for invoices, receipts, statements, forms and scanned pages: PDF or image URL in, full text plus extracted fields out (dates, money amounts, totals/tax/amount due, invoice or order numbers, key: value pairs, emails, phones, URLs, simple tables). Images and scans use OCR.

Document parsing from uploaded bytes. POST a raw PDF (max 20 MB, text layer) or PNG/JPEG/WebP image (max 10 MB, OCR) as the body with its content-type; multipart 'file' or JSON {"base64"} also work. Returns text plus dates, amounts, totals, IDs and tables. Bad files get HTTP 400 with a hint and are not charged. Samples: https://agents.crowdspark.me/samples/sample.pdf

Domain intelligence for due diligence, phishing checks and lead research: registrar, creation and expiry dates (RDAP/WHOIS), A/AAAA/MX/NS/TXT records, SPF, DMARC and HTTPS reachability in one call.

Email validation for signup forms, lead lists and CRM cleanup: checks syntax, MX mail servers, disposable or temporary domains, role addresses (info@, sales@) and free providers. Returns a deliverable_guess. No SMTP probe, no data stored.

One call email risk check: everything in email_check plus sender domain health (domain age, registrar, SPF, DMARC, website reachable) and a 0-100 risk score with accept/review/reject verdict. Use for fraud screening, lead qualification and signup gating.

OCR: read all text from a screenshot, photo, receipt, sign, scanned page or chart image at a URL (PNG/JPEG, max 10 MB). Keeps line breaks.

OCR from uploaded bytes. POST the raw image as the body with its content-type (image/png, image/jpeg or image/webp); multipart 'file' or JSON {"base64"} also work. Real PNG, JPEG or WebP only, max 10 MB. Returns {text}. Bad files get HTTP 400 with a hint and are not charged. Sample: https://agents.crowdspark.me/samples/sample.png

PDF to text or markdown for RAG, summarizing, search indexing and reading reports, papers, contracts and invoices. Give a PDF URL (max 20 MB); returns text per page. format=text or markdown. Not stored.

PDF to text from uploaded bytes. POST the raw PDF as the body (content-type application/pdf); multipart 'file' or JSON {"base64"} also work. Real PDF only (starts with %PDF), max 20 MB, with a text layer. Optional ?format=text|markdown. Bad files get HTTP 400 with a hint and are not charged. Sample: https://agents.crowdspark.me/samples/sample.pdf

Timezone conversion for scheduling meetings and deadlines across IANA zones, with DST-correct UTC offsets. time=ISO local time or 'now'.

Read a web page as clean LLM-ready markdown (main content, no nav or scripts) for research, RAG and summarization. Respects robots.txt.

One call page reader: clean markdown plus page metadata (title, description, Open Graph, canonical, favicon), outbound links, word count and extracted dates, prices, emails and phones. Use for research agents, price checks and lead enrichment from public pages.

x402 readiness check for any paid API URL: probes it without paying and reports whether it returns a valid 402, where the requirements are (header or body, v1 or v2), network, asset, price in USD, payTo (with EIP-55 checksum check), EIP-712 token domain, timeout, resource URL and Bazaar discovery. Returns ready or needs_fixes with a 0-100 score and a list of specific issues. Use before listing an endpoint or paying it. Never pays.

Token preflight for agents about to swap, list or pay with a token on Base, Ethereum, Optimism, Arbitrum or Polygon: contract and standard check, name, symbol, supply, proxy and owner flags, a 0-100 structural risk score with reasons, plus a simulated ERC20 transfer gas cost in USD. Not a honeypot audit.

One call dossier on a web page and its host: clean markdown, page metadata, outbound links and extracted fields, plus domain intelligence (registrar, age, DNS, SPF, DMARC) and IP network lookup for the host, with a short trust summary. Replaces three calls.

Wallet balance on Base, Ethereum, Optimism, Arbitrum or Polygon: native coin balance with USD value (Chainlink) plus up to 10 ERC20 token balances with symbol and decimals. Pass tokens=0xA,0xB. Read live from public RPC. Use before funding, swapping or paying from a wallet.

ENS lookup: name to address (with avatar) or address to primary name, with forward verification. Read live from Ethereum mainnet. Use name=vitalik.eth or address=0x... Use before sending funds to a human readable name.

Transaction decoder for Base, Ethereum, Optimism, Arbitrum and Polygon: status, from, to, value, gas used, fee in native coin and USD, method name and arguments for common ERC20 calls, ERC20 transfers with symbols and amounts, and approvals. Use to confirm a payment landed or explain what a transaction did.

Batch email validation for list cleaning: up to 10 addresses per call, 40% cheaper than 10 single calls. JSON body {emails:[...]}. Each item gets syntax, MX, disposable, role and free-provider checks and a deliverable_guess. Bad items return per-item errors, not a failed call.

Will my paid API get listed? Audits any x402 endpoint URL: runs the readiness check, flags the 500 character description limit, then checks the Coinbase Bazaar listing, OpenAPI x-payment-info, 402 Index entry, favicon, llms.txt and /.well-known/x402. Returns a 0-100 score, verdict and an ordered fix list. Never sends a payment.

Invoice intake for AP agents: PDF or image URL in, one decision-ready JSON out. Extracts text, number, total, dates and vendor contact, then runs an email risk check and domain lookup on the vendor and returns accept, review or reject with reasons. Heuristic triage, not bank verification.

Invoice intake from uploaded bytes. POST a raw PDF (max 20 MB, text layer) or PNG/JPEG/WebP (max 10 MB) with its content-type; multipart 'file' or JSON {"base64"} also work.

Batch IP lookup for log analysis and fraud review: up to 10 IPv4 or IPv6 addresses per call, 40% cheaper than singles. JSON body {ips:[...]}. Each item returns the owning network, range, country (RDAP) and reverse DNS. Bad items return per-item errors.

Due-date calculator: add or subtract N business days from a date, skipping weekends and nationwide public holidays for a country (ISO code). Returns the result date and weekday, which holidays were skipped and whether the start day is a working day. For SLAs, invoice terms, shipping and legal deadlines.

Link health check: follows redirects hop by hop (max 8) with status and timing, flags loops and https downgrades, then reports final status, content type and size, server, caching and a security-header grade (HSTS, CSP, nosniff, frame, referrer, permissions). Public hosts only.
