Read the latest Base mainnet block and a bounded EIP-1559 fee history in one RPC batch, including gas utilization and priority-fee percentile samples.

Resolve one global city or locality name into bounded, population-ranked GeoNames coordinates, country and first-level-region identity, population, timezone, feature code, and source freshness without a request-time network call.

Get and inspect one historical Base mainnet block by exact number or a latest, safe, or finalized tag, returning its header timestamp, transaction count, gas use, base and blob fees, state and receipt roots, confirmations, and head-distance evidence.

Convert and extract a public website URL into clean Markdown or readable text plus bounded structured links, canonical and heading signals, Schema.org types, redirect evidence, content hashes, and response provenance for RAG, research, or agent context.

Paste one public retailer product URL to get its current publisher-supplied structured price, currency, availability, seller, shipping terms, aggregate rating, variant attributes, identifiers, observation time, and evidence hashes from Schema.org JSON-LD, Schema.org microdata, or paired product meta tags; optionally compare the selected offer with a buyer-supplied maximum. Fetching proceeds only when robots.txt permits it, without JavaScript, login, cookies, or anti-bot bypass.

Read point-in-time ETH, native USDC, and up to four caller-selected ERC-20 balances plus account nonce and contract-code status at one resolved Base mainnet block.

Clean CSV, TSV, JSON, JSON Lines, or YAML records with collision-safe header normalization, deterministic integrity hashes, and exact transformation counts.

Remove duplicate CSV, TSV, JSON, JSON Lines, or YAML records using selected identity fields and report the removed count.

Validate JSON data against a bounded JSON Schema Draft 2020-12 contract for nested objects, arrays, required properties, types, enums, formats, lengths, patterns, and numeric bounds; return deterministic instance and schema JSON Pointers, explicit error truncation, input hashes, and no remote reference resolution.

Get a global weather forecast for a city/locality name or exact coordinates. Returns normalized day/night or hourly periods worldwide: NOAA/NWS is preferred within supported U.S. coverage for optional station conditions and active alerts, while MET Norway provides an attributed open-data fallback globally.

Compare JSON or YAML deterministically and return source hashes plus machine-readable additions, removals, and replacements by path with explicit truncation evidence.

Compare two texts and return structured line additions, removals, and a unified diff.

Extract clean text and metadata from supplied PDF, DOCX, HTML, Markdown, CSV, JSON, YAML, or plain-text documents.

Fetch and normalize public RSS or Atom feeds into stable structured JSON entries for agents and research workflows.

Check a public domain's email authentication and anti-spoofing posture using MX, SPF, DMARC, caller-selected DKIM, MTA-STS, TLS-RPT, and BIMI DNS evidence.

Extract webpage metadata from one public URL: page title, meta description, canonical URL, headings, hreflang, icons, feeds, Open Graph, Twitter Cards, and JSON-LD Schema.org types, with redirect and response provenance plus privacy-safe, publisher-asserted Organization facts with field evidence.

Validate EIP-712 typed structured data and derive its domain separator, message hash, and signing digest.

Convert caller-supplied CSV, TSV, JSON, JSON Lines (NDJSON), or YAML with optional root preservation, deterministic integrity hashes, JSON-encoded nested tabular cells, and explicit rejection of ambiguous duplicate keys or non-finite numbers.

Resolve one latitude/longitude pair into bounded, great-circle-distance-ranked nearby GeoNames populated places with country, first-level region, population, timezone, feature code, and source freshness without a request-time network call.

Deterministically detect and redact PII and personal data in supplied text with overlap-safe matching for emails, phone numbers, validated IPv4 and IPv6 addresses, Luhn-valid payment cards, valid-checksum IBANs, and structurally valid US Social Security numbers.

Resolve one DOI into normalized open Crossref bibliographic, author, container, citation-count, license, identifier, and correction or retraction-link metadata without abstracts or full text.

Search the official GLEIF Global LEI Index by exact LEI or legal name and return ranked legal-entity identity, registration, mapped-identifier, and relationship-availability evidence.

Extract and classify links from one public page or safely crawl up to 10 same-origin pages into an agent-ready site map with page provenance, depth limits, and robots.txt enforcement.

Audit one public URL for title, meta description, H1 count, image alt text, canonical, robots, language, Open Graph, Twitter cards, headings, hreflang, feeds, and Schema.org data; return a deterministic score and prioritized issue codes.

Check one Base mainnet wallet or contract for ETH and official USDC balances, transaction nonce, and contract-bytecode evidence at a single resolved block.

Inspect Base mainnet contract bytecode, common token metadata, and ERC-165, ERC-721, and ERC-1155 interface signals at one resolved block.

Execute one bounded read-only eth_call against a resolved Base mainnet block, retain call and block evidence, and optionally decode caller-specified ABI output types.

Estimate gas for one Base mainnet transaction context at a resolved block, add a bounded caller-selected buffer, and preserve RPC rejection evidence without signing or broadcasting.

Inspect Base transaction status and receipt evidence in one call, including success, revert, or pending state, confirmations, actual gas fee, recognized calldata, bounded ERC-20-shaped transfers, and official Base USDC recognition for payment confirmation.

Retrieve newest-first incoming and outgoing Circle USDC Transfer events for one address across a validated, bounded Base mainnet block range.

Repair caller-supplied malformed JSON by safely removing an outer Markdown fence, comments, single-quoted strings, unquoted identifier keys, Python literals, and trailing commas, with transformation hashes and strict rejection of duplicate keys or non-finite numbers.

Geocode one structural address in the United States, Puerto Rico, or U.S. Island Areas with normalized U.S. Census MAF/TIGER coordinates, optional bounded state/county/tract/block/congressional geography, exact source attribution, and explicit range-interpolation limits.

Decode a full 17-character VIN into normalized NHTSA vPIC make, model, year, body, engine, transmission, plant, fuel, and occupancy fields with official source evidence and explicit missing-data semantics.

Detect likely leaked API keys, tokens, private-key headers, JWTs, and credential assignments in caller-supplied source or configuration text. Return type, line, fingerprint, and a fully redacted preview with no network access or code execution.

Measure website response latency, payload size, compression, caching, and performance signals for a public URL.
