  64. 95agenttools-hub.vercel.app/api/v1/crypto/tx-explainExplain what an EVM transaction would actually do: decodes the calldata (ERC-20 transfers/approvals via known ABIs, unknown selectors via the 4byte directory) and simulates the call against live chain state to report the outcome — including unlimited-approval warnings — without sending anything.

  65. 95agenttools-hub.vercel.app/api/v1/crypto/new-poolsScan newly created DEX pools on Solana, Base, Ethereum, BSC, Arbitrum or Polygon, filtered by minimum liquidity and maximum age.

  70. 95agenttools-hub.vercel.app/api/v1/dev/directory-searchDescribe what you need and get back matching x402-paid APIs: our own catalog (54 tools) plus, optionally, the live x402 Bazaar of third-party sellers. The agent's meta-tool — instead of knowing an API exists, ask for the capability. Use this when an agent needs to "I need a tool that does X" → matched paid APIs.$0.002 Base485 ms1 payers100% up
  71. 95agenttools-hub.vercel.app/api/v1/dev/url-readerFetch a web page server-side and convert it to clean markdown — headings, links, lists, tables and text, with scripts, styles and boilerplate stripped. The 'reader' pattern agents use to actually understand web pages. SSRF-guarded with redirects re-validated, 10s timeout, 1MB cap. Use this when an agent needs to fetch any page and get clean markdown an LLM can read.$0.005 Base537 ms1 payers100% up
  72. 95agenttools-hub.vercel.app/api/v1/dev/pdf-to-textFetch a PDF (by URL, SSRF-guarded) or accept it as base64 and extract all readable text with page count. Deterministic parsing — no language model, so nothing is invented. Text-based PDFs only; scanned images need OCR (not included). Use this when an agent needs to extract readable text from any PDF — agents can't read PDFs.$0.003 Base399 ms1 payers100% up
  73. 95agenttools-hub.vercel.app/api/v1/crypto/wallet-snapshotOne-call on-chain profile of any Ethereum or Base wallet via Blockscout: native balance, transaction and transfer counts, activity recency, top token holdings, and most frequent recent counterparties — with fresh-wallet and high-volume flags.

  75. 95agenttools-hub.vercel.app/api/v1/dev/url-parserParse a URL into all its components: protocol, hostname, port, path segments, query parameters (as a clean object), hash and credentials.

  76. 95agenttools-hub.vercel.app/api/v1/dev/diffCompare two texts line by line using an LCS diff: exact additions, removals and context — in unified-diff style.

  77. 95agenttools-hub.vercel.app/api/v1/dev/text-extractScan unstructured text and extract structured entities: email addresses, URLs, IPv4 addresses, phone numbers and domains.

  79. 95agenttools-hub.vercel.app/api/v1/dev/hashCompute exact hash digests of UTF-8 text using Web Crypto (SHA family) and a verified pure-JS MD5 for legacy checksums.

  80. 95agenttools-hub.vercel.app/api/v1/dev/text-chunkerSplit text into retrieval-friendly chunks with a token budget and sentence-aware boundaries. Overlap between consecutive chunks preserves context across splits — the standard preparation step before embedding. Use this when an agent needs to rAG-ready chunks with token budgets and overlap.$0.002 Base351 ms1 payers100% up
  81. 95agenttools-hub.vercel.app/api/v1/dev/llm-cost-calculatorCalculate the API cost of an LLM call: input and output tokens × published per-million prices for 15 current models (OpenAI, Anthropic, Google, DeepSeek, xAI, Meta). Batch multiplier included for monthly estimates. Use this when an agent needs to tokens × current per-model prices = USD.$0.001 Base480 ms1 payers100% up
  82. 95agenttools-hub.vercel.app/api/v1/dev/token-estimatorEstimate how many tokens a text consumes for each major model family (GPT, Claude, Gemini, Llama, DeepSeek) using a character/word heuristic that is within ~10% of real BPE tokenizers — enough for context budgeting and cost math, with zero dependencies.
