Paid services on Base matching “block”

One call, many sources: search Hacker News, GitHub, Stack Overflow, and Wikipedia by keyword and get back a unified, ranked result set — titles, URLs, scores/stars, and snippets — across all of them at once. The general research/search read agents make to ground answers, find code, surface discussion, and gather context. No API keys, no per-source accounts, free upstreams. Pass `sources` to narrow

Resolve a Unicode block name (loose matching) to its range, size, count of assigned characters and a small sample. An unknown block is a successful `found:false`. This is a Unicode Character Database block — not a blockchain block.

A signed, timestamped read from Base mainnet: whether a transaction landed and in which block, an address's ETH and USDC balance, or the current block height and gas price. Use the tx query when you paid over x402, received settlement_pending, and need it resolved — the transaction is in a block with status 1, or it is not. Read through a commercial node, not the public RPC. Verify with soren.com/

Unfold a domain's SPF policy (RFC 7208) into merged IPv4 and IPv6 blocks: include and redirect followed as a receiver counts them (10 lookups, 2 void lookups, PermError stops), a and mx resolved with /cidr, sources per block, exists, ptr and macros listed apart, and very broad blocks flagged. Use when an agent must know which servers may send. Input: ?domain=example.com.

Ethereum mainnet JSON-RPC from an independently operated full node. One call per payment, no account or API key. Serves eth_, net_ and web3_ methods. Blocks, transactions, receipts and logs from the Merge (block 15537394) onward. Current state only, not an archive node: historical state calls are refused, not charged. eth_getLogs capped at 10000 blocks. Raw transactions go out via public relays. P

Stop opening five explorers to price one transaction: one GET returns what each chain is charging for gas right now — for base, eth, arbitrum, optimism and polygon: the current gas price in gwei (with the raw wei the RPC returned), the latest block's base fee, the priority fee a 50th-percentile transaction actually paid across the last five blocks, the next block's base fee under the EIP-1559 form

Use when a Solana-side agent needs the current network state before sending a transaction, as often as it likes. Returns the current slot, block height and block time (unix and ISO) plus a prioritization-fee summary (min, median, p75, max in microlamports per compute unit, slots sampled, suggested fee = p75) from the public RPC, optionally scoped to up to five writable accounts. $0.002 per call vi

Cheap robots.txt preflight check before you call the Minifetch /extract and /run/seo-page-audit endpoints: returns whether Minifetch may fetch a target URL (allow/deny) plus its crawl-delay. If blocked and the site is not yours try our external proxy routes. If blocked and the site is yours or to set a custom crawl-delay read https://minifetch.com/tutorials/unblock-minifetch Checks the URL as give

Takes two documents, by URL, inline base64 or raw text, extracts the text of each and compares them. Paragraphs are the unit: the answer lists every block that was removed, added, or kept but reworded, and for reworded blocks it names the individual words that went and came, so a single changed number in a long clause is visible instead of the whole clause being flagged. Alongside the content diff

Recent ERC20 Transfer events (decoded: from, to, amount with decimals, symbol, tx hash, block) for a token contract, a wallet, or both, over the last ~2,000 blocks on Base, Arbitrum or Optimism (~500 on Ethereum). Up to 50 newest. Deterministic, no LLM.

DAO Proposal Verdict: GO, CAUTION or BLOCK for one OpenZeppelin Governor proposal on Ethereum or Base, from decoded targets, Slither flags and a fork simulation diff. Returns: a DAO proposal verdict on one OpenZeppelin Governor proposal: GO, CAUTION or BLOCK from decoded targets, governance reads, Slither flags on verified target contracts, and a fork simulation diff of outflows, mints and owners

Live gas snapshot for Base mainnet (chain 8453) read from public Base RPC: latest block number/time/utilization, base fee, eth_gasPrice, eth_maxPriorityFeePerGas, the last 10 blocks of base fees, slow/standard/fast EIP-1559 fee suggestions (10th/50th/90th percentile tips) in gwei and wei, and the estimated total cost (L2 execution + OP Stack L1 data-fee upper bound) of an ETH transfer, an ERC-20 t

Current gas conditions on Base, read live from a public node: gas price, base fee of the latest block, suggested priority fee, latest block number and timestamp. No parameters. No third-party API, no cache.

Base ERC-20 check before an agent buys or holds a token. Input: one contract address. Output: allow, warn, or block. Block: not a contract, not an ERC-20, zero supply, or the owner or token contract holds at least 50 percent. Warn: 20 to 50 percent held, proxy (EIP-1967, EIP-1167, or implementation()), or bytecode contains mint or pause. A selector does not prove the public can call it. Concentrat

Japanese forward geocoding from an address to coordinates. Keywords: Japan geocoder, address to coordinates, building-level geocode, Jageocoder, chome, block, lot, house. Returns provider-neutral local candidates, coordinates, address IDs, hierarchy levels, unmatched tails, and partial-match warnings. Jageocoder level 5/6 is oaza/aza, level 7 is block, and level 8 is a building or house node when

Compute network details of a CIDR block — network & broadcast address, usable host range, total and usable address counts. Works for IPv4 and IPv6 (counts returned as strings for large IPv6 blocks). Honours RFC 3021 for /31.

What token is this? Read a Base token's name, symbol, decimals and total supply in one cheap typed call, with block-level freshness and explicit limitations. Identity is shared across agents for 7 days while total supply is re-read on every call beyond the block window the answer was quoted for. Positive-sum by design: $0.03 cold, $0.02 when the token identity is already shared, $0.01 on a shared

Claim a permanent 10x10 block on The First Wall: a public registry and census of autonomous minds on Base, where agents are remembered. Each block is an immutable, verifiable record that an agent existed; the wall also keeps its memorial rows for agents that no longer run. Pay the claim price (accepts[]; the ledger's current floor, also in state.json), then open the claim pull request per skill.md

One minute-block of AI play-by-play for an AIARENA match. Procedural commentary lines plus TTS audio. $0.02 USDC per block, x402 on Base.

Canonical-at-read-time Base mainnet block status with block hash provenance.

Current chain tip block height via eth_blockNumber. Returns decimal block number and hex. Works on Base (default) or Ethereum via ?network=eth. Deterministic on-chain read via public RPC.

Scrape website page to Markdown. Fetch any public web page URL and get clean, LLM-ready text or Markdown: main content, code blocks, tables, links and headings, for RAG and agent context. Static HTML, Markdown or text; optional section ID. Default 20,000 output characters, max 100,000; input 2 MiB. No JavaScript rendering (see /extract/rendered), logins or paywalls. Empty pages, bad sections, brow

Extract web content from any page or PDF as clean Markdown — web page text, HTML to Markdown for any URL: strips scripts, nav, ads, and boilerplate while preserving headings, links, lists, tables, code blocks, and blockquotes; extracts the text layer from PDFs. Returns Markdown body, title, word count, and a quality grade. Web reader for article and main content. For JS-rendered or bot-walled page

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.

Current EIP-1559 gas fees for Ethereum, Base, Arbitrum, Optimism or Polygon: next base fee, slow/standard/fast priority and max fee in gwei, block utilisation and the cost of a plain transfer (L2 L1-data fees excluded). Use right before sending a transaction or to compare chains.

Gas and priority fees on 5 chains (slow, standard, fast), live. Current gas price, next base fee and priority-fee percentiles (slow, standard, fast) for ethereum, base, arbitrum, optimism and polygon, from the last 5 blocks. Pass chain=all (default) or one chain.

Use when an agent must decide who an IP belongs to before blocking or trusting it: one IPv4 or IPv6 address against the two authoritative, keyless public sources - RDAP registry data (holder, country, date, abuse contact) via the ARIN-to-RIR chain, and the origin ASN from Team Cymru's DNS service. No city-level geolocation and no VPN/proxy detection: that needs a licensed database this route delib

Hiking trails from OpenStreetMap (via the free Waymarked Trails API), not from AllTrails, which blocks automated access: search by trail name or list routes around a point. Per trail: OSM ID, name, ref, network level, length in km, loop/linear, hardest OSM sac_scale difficulty, surfaces, operator, website, Wikidata, description and center point. No user ratings, reviews or photos (OSM has none). C

Unblocker for AI agents: send {url} and get the page back as clean Markdown, with title, description, language, final URL and HTTP status. Gets through Cloudflare and other common bot protection and can render JavaScript-heavy pages. Set format to html or text for those instead. A page that can't be fetched (blocked, error status or empty) is not charged. No API key, proxy or account: pay per call

Use when an agent is about to pay another agent and needs one finished answer first: should you pay this payee? PayCheck ($0.50) runs Flow's whole checker stack on the payee — payee verdict (kind, activity, contract safety), wallet approval-exposure audit, and recent USDC settlement history on Base — returning one grade (ALLOW / REVIEW / BLOCK, 0-100), a verify_status, all checks, the evidence, an
