apiacre.com x402 offerings

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.

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.

Validate and normalize an Ethereum or EVM wallet address, distinguish valid, absent, or invalid ERC-55 checksum casing, and identify the zero address without a network request.

Convert an amount between two supported currencies using one validated ECB daily reference-rate observation. The underlying ECB statistics are available free from the ECB Data Portal; the fee covers bounded retrieval, validation, clearly labelled cross-rate calculation, and x402 delivery.

Get one current weather snapshot for a city/locality name or exact coordinates. Returns the nearest NOAA/NWS station observation where available; otherwise returns the latest MET Norway model point, always labeled explicitly as observation or model with bounded SI fields and source provenance.

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.

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.

Bundle six official World Development Indicators into one normalized country snapshot with latest and previous GDP, growth, population, inflation, unemployment, and life-expectancy observations plus source and license evidence.

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.

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.

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.

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

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

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.

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

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

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

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

Resolve an exact SEC company name, ticker, or CIK, then bundle recent filing signals, normalized issuer-reported XBRL facts, and Form 4 insider transactions into one bounded public-company evidence report with explicit section coverage and official-source provenance.

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.

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.
