Multi-page research brief with cited sources. Crawl one URL and follow its links, or pass a list of URLs, and get a synthesized answer to your question as JSON with a sources array, optionally shaped by your JSON Schema. Use it to compare several pages, gather a list across a site, summarise a topic from multiple sources, or answer a question that spans documents. Up to 8 pages per call, typically

Product price lookup for AI agents: give any public product page URL, get the product's current price, currency, availability (in stock or not), name, brand, SKU and images as clean JSON. The page is rendered in a real browser, so JavaScript stores work, and the store's own schema.org product data is read first. For price checks, price monitoring and comparing stores before you buy.

Takes a kind 9735 receipt directly or fetches it from relays by event id, then runs eight named checks and reports each one separately with its reason. The receipt signature and the signature of the zap request enclosed in the description tag are verified per BIP-340. The invoice is decoded and its amount is compared against the amount tag of the zap request, since those two can disagree and only

You get a checked official record: the official source hash and a Bitcoin stamp. That is Official checked records. Compare a model, a tweet, a FRED series, or the wrong table to this hash. If they differ, that copy is dirty. It is $0.25 per record_id. Not a stamp on a free PDF. Agent Trust Score comes from graded Proof of Outcome claims.

Collectible value & price check: trading card value, graded card (PSA/BGS/CGC) price, coin value, comic & vinyl record price. Returns current market value by grade and condition with recent sold comparables (eBay/Discogs) for any item: cards, coins, comics, watches, sneakers, vinyl. Worldwide. For collector and investor agents.

Verify a claim against 2-4 source URLs: cited passages, cross-source agreement, verdict: consistent | conflicting | insufficient_evidence. Evidence, not truth. Use when your agent needs to verify a claim against independent sources before acting on it. Give a claim plus 2-4 source URLs; each source is extracted (three-fetch cross-check, confidence-scored), the checkable figures are compared across

PRICE: 0.01 USDC. Identity-matched market intelligence for Japanese anime collectibles. Resolve the exact product first, then compare supported Japan and global marketplace observations while rejecting likely wrong editions and name collisions. Returns low/median/high asking prices, offer count, freshness and best matched listing. WHEN TO USE: Use when an agent needs current value, resale context

Calculate kg/l unit prices for up to 50 rows of price_eur plus quantity text or EAN. Example: items [{price_eur:1.29,quantity:"500 g"}]. Errors are reported per row; kg and litre groups are not comparable. Empty batches with no usable line are not charged. No observed store offer.

FetchDelta: compare one public web page with its previous stored snapshot. Returns added/removed lines and change previews. The first call creates a baseline; later calls share that URL baseline across buyers. Use page-watch-30d for a private daily watch.

Pre-payment check of an x402 API endpoint: discovery files, live 402 terms, comparable USDC prices, latency, prompt-injection flags and public Coinbase CDP Bazaar payment statistics for the host. Heuristic, not a guarantee. $0.002; unreachable targets are free. Online shops: pre_purchase_merchant_trust_check.

Agent income rebuild: every payment into an agent wallet in one asset (an ERC-20, or native ETH including escrow withdrawals) between two blocks, with the draft Agent Income Statements exclusions (zero, mints, self, optional owner top-ups), payers that are contracts flagged, and an optional claim= compared as matched or mismatched. Ethereum, Base and Robinhood Chain. Independent, by Blockpin; not

Compare current perpetual funding rates across Binance, Bybit, Hyperliquid, and, for single-symbol requests, OKX. Returns interval-normalized annualized rates, gross cross-venue spreads, source status, mark prices when available, and funding timestamps. Optional symbol query; no symbol returns the ten widest current spreads. Market data only, not financial advice.

Country inflation and CPI history from World Bank WDI: annual consumer-price inflation (%) and consumer price index (2010=100), by ISO3 country for the last 1-10 complete years. Includes independent latest values, units, nulls, source update date and IMF/CC BY attribution. Annual history, not monthly releases or forecasts; CPI levels do not compare prices across countries.

Agent income rebuild: every payment into an agent wallet in one asset (an ERC-20, or native ETH including escrow withdrawals) between two blocks, with the draft Agent Income Statements exclusions (zero, mints, self, optional owner top-ups), payers that are contracts flagged, and an optional claim= compared as matched or mismatched. Ethereum, Base and Robinhood Chain. Independent, by Blockpin; not

Tracks how much is written about an organisation and in what tone, comparing a recent window against the same term own longer baseline, and returns both the volume ratio and the tone shift with the articles behind them. The framing is fixed and repeated in the response: this is an attention signal and not a judgement. A tone drop means more negative language is being used, not that something happe

Flight search by departure and arrival airports in the URL — compare live itineraries, fares, schedules, stops and emissions across airlines, similar to Google Flights, as clean JSON.

Starts a website migration comparison: checks page existence, content and visual regression between a source site and its migrated copy, then produces a report with screenshots. Use it to verify a migration or redesign before go-live. Priced on the pages it compares (the urls list, or the pages discovery finds, at most the optional maxPages ceiling), no page limit: 0.02 USD per page for the first

Compare an agent's advertised contract with its live x402 challenge and return deterministic proof.

Is this x402 seller actually paid, compared with every other one? One row out of our weekly read of every seller on Base, where all of them get the SAME window, so the number means the same thing seller to seller. Give a payTo address: verdict (paid, single-payer, self-funded, dust-only, silent), payers, how many the seller itself funded, USDC in. Call counts are not payments; of 1 397 sellers rea

Returns measured evidence about a recording, not a verdict on it. The spectral cut-off says which lossy stages the file has already been through, since every encoder discards everything above its own ceiling. The room tone measurement compares the noise floor across the silent stretches: a microphone in a room produces a floor that differs between pauses, and a level identical to the hundredth of

Check an x402 seller before you pay it. Probes the endpoint now, checks that its payment can actually succeed (token EIP-712 domain, payTo), and adds its 30-day uptime from our monitor of paid Bazaar listings, how many distinct buyers paid it, and how its price compares with similar listings, with cheaper well-used alternatives. Returns a verdict (ok, caution, avoid) with the reasons.

Resolves two products to their RxNorm concepts and compares what the register declares about each: the active ingredient set, the strength per ingredient, the dose form and the route of administration. Every difference is listed individually rather than collapsed into a verdict, and matching ingredients with differing strengths are reported as such rather than as a match.

US Treasury interest rates — latest monthly average rates on outstanding government debt, including Treasury bills, notes, bonds, TIPS, floating-rate notes and savings securities. Track federal borrowing costs and compare rates across security classes.
