What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of payai.agentstools.dev controls every word below.
web-extract
Fetch any public web page and return its main readable content as clean Markdown or plain text plus metadata (title), stripping nav/ads/boilerplate (trafilatura). Optional JS rendering via headless browser for SPAs; markdown or text output. Robots-respecting, public content only — the reader/scraper building block for RAG and agent pipelines.
web-search
Free-text web search for AI agents: ranked title/url/snippet results fused across multiple engines (Brave, Google, DuckDuckGo, Mojeek, Startpage, Yahoo), with freshness filters (past day/week/month/year), region/locale and SafeSearch. One call for grounded, up-to-date web results — no keys, no scraping setup.
web-news
Keyword news search across web news engines (Bing/DuckDuckGo/Yahoo via ddgs). Returns dated headlines with title/url/snippet/source/image + freshness/region/safesearch filters.
onchain-price
On-chain USD spot price for 50+ assets from Chainlink feeds or the most-liquid Base DEX pool (computed from public chain state): crypto majors, stablecoins, Base-native tokens, forex currencies and precious metals.
onchain-gas
EVM gas oracle for any major chain - Ethereum, Base, Arbitrum, Optimism, Polygon, BNB, Avalanche: next-block baseFee plus slow, med and fast priority-fee tiers (maxFeePerGas and maxPriorityFeePerGas), read live from chain state in one call. Choose network (default Ethereum). EIP-1559 and legacy handled.
onchain-market-report
Rich cross-source market report for 50+ assets (crypto, stablecoins, forex, metals): Chainlink + DEX pools, TVL-weighted VWAP, total pool TVL, recent change and volatility — all computed by us from on-chain state.
onchain-token-meta
ERC-20 token metadata on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base): name, symbol, decimals and totalSupply (raw + human), read live from contract state by address.
onchain-wallet-balances
Native-coin balance + ERC-20 token balances (raw + human) for any address on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base). On Base pass token symbols or 0x addresses (or a default common set); on other networks pass explicit 0x token addresses.
onchain-code
Is an address a contract or an EOA on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base)? Returns is_contract, deployed code size in bytes, and the keccak256 code hash (eth_getCode).
onchain-tx
Look up a transaction by hash on Base, Ethereum, Arbitrum, Optimism, Polygon or BNB (default Base): from/to/value/nonce/gas, block, and receipt fields (status, gasUsed, logs count). Pending/not-found handled.
onchain-tx-explain
Plain-language explanation of an EVM transaction by hash across 12 networks: net token movements per participant (ERC-20, ERC-721, ERC-1155, native, WETH), the operation type (swap, transfer, approve, mint, deploy, wrap, and more), protocol labels, gas in native plus USD, and a readable summary.
onchain-resolve
Basename/ENS resolution on Base: forward name->address (give 'name') or reverse address->name (give 'address', forward-verified against spoofing).
crypto-verify
Verify an EIP-191 personal_sign or EIP-712 typed-data signature and recover the signer address from public inputs (message + signature). Verification/recovery only — never signs.
crypto-abi
ABI-encode a function call (selector + args) or encode/decode arbitrary ABI types — build and parse EVM calldata correctly.
crypto-hash
Compute keccak256/sha256, a 4-byte function selector, an event topic0, or an ENS namehash/labelhash from a string or hex input.
crypto-convert
Convert token units (wei/gwei/ether or arbitrary decimals), between hex and int, and compute/validate an EIP-55 checksummed address.
data-convert
Pure-compute data format conversion (no network): JSON<->CSV, JSON<->YAML, JSON normalize/minify, Markdown->HTML (sanitized), HTML->Markdown/text, base64/hex, TOML->JSON. Operates only on the supplied data.
web-structured
Structured parse of a public web page: main text, headings, links, tables and rich metadata (description, canonical, lang, Open Graph, Twitter cards, JSON-LD) as separate fields. Browserless, robots.txt-respecting.
web-feed
Parse an RSS, Atom or JSON Feed URL into a normalized item list (title/link/published/summary/id/author) plus feed-level metadata.

dex-swaps
Recent DEX swap history + buy/sell flow for a token or pool on Base: per-swap trader/side/amount/price plus a summary (count, buy/sell volume, net flow, largest swaps), decoded by us from public Aerodrome/Uniswap-V3 Swap event logs.
dex-trending
Trending Base DEX pools ranked by recent swap volume and net buy/sell flow over a short window, computed by us from public Aerodrome/Uniswap-V3 Swap event logs.
enrich-domain
Enrich a domain / company / email into one aggregated profile from public sources: registration (RDAP/WHOIS age, registrar, expiry, nameservers), DNS (A/AAAA/MX/NS, SPF, DMARC), TLS certificate (issuer, validity, expiry), homepage metadata (title, description, Open Graph, JSON-LD Organization, social links, role contacts) and a tech-stack detection. Each block is null-on-failure (partial, never 500). Business/domain data only — no personal data of individuals.
enrich-email
Validate and classify an email DOMAIN from public DNS: MX hosts + mail-provider, SPF and DMARC policy, plus disposable / free-webmail / role-account flags and a deliverability signal. No SMTP probing of individual mailboxes (privacy + ToS).

kyb-screen
Screen a company name against the GLEIF business registry: fuzzy name search returning ranked candidates, each with its LEI, legal name, jurisdiction, registration status and corroboration level. Cheap first step before kyb/verify.
kyb-verify
Verify a business is real and get a legitimacy verdict plus a 0-100 risk score. Give one of name, lei, cik, ticker, isin or qid and get a verdict (real, likely_real, inactive, dissolved or not_found), a risk category, per-dimension flags, reasons, the official registry and which registries corroborated. Deterministic scoring, no LLM. Legitimacy indicators, not legal or credit advice.
