Wallet monitoring for agents: watch an EVM address and get only what changed since your last call: native coin and token balance deltas (USDC always included, up to 10 more tokens) and the number of outgoing transactions. Read directly from the blockchain. First call saves a baseline and returns a cursor; pass it on the next call. For treasury and payment tracking, whale and smart-money watching, deposit detection. Chains: base, ethereum, bsc, arbitrum, polygon, avalanche, optimism.

Watch a Tron address for USDT and USDC (TRC-20) transfers in a loop: each call returns only transfers since your last call with amount, direction, counterparty, time and link, plus the TRX balance. First call covers the last hour (lookback_hours up to 6) and returns a cursor; pass it back next time. For deposit detection and payment confirmation on Tron.

RSS and Atom feed monitoring for agents: returns only the items that are new since your last call, never the same item twice. First call saves a baseline and returns a cursor; pass it on the next call. Works with news feeds, blogs, GitHub releases (.atom), YouTube channel feeds, subreddit .rss, podcasts, job feeds. Params: url (feed URL), cursor, limit (max new items returned, 1 to 50, default 20).

Invoice data extraction for accounting agents: PDF, photo or XRechnung / ZUGFeRD / Factur-X XML to JSON (number, dates, seller and buyer with VAT ID, line items, tax per rate, totals, IBAN, payment terms).

Says whether the file is a real EN 16931 e-invoice. Up to 15 MB.

Website change monitoring for agents that check in a loop: send a URL and get only what changed since your last call (added and removed lines of the page text), plus optional keyword alerts. First call saves a baseline and returns a cursor; pass the cursor on the next call. The cursor only advances when a change is reported, so nothing slips through between polls. Good for price pages, docs and changelogs, job boards, status pages, competitor sites, government notices.

Which countries hold bitcoin? Every frozen monthly snapshot of national (sovereign) bitcoin reserves by country, with sources, in one call. Not investment advice.

Check a web page for changes: each call compares the page's readable text with your previous check of the same URL (kept per paying wallet for 90 days) and returns whether it changed, when you last checked, and the added and removed lines. The first call records the page. Use name to keep several watches of one URL apart.

A mailbox for AI agents, no account: create an inbox and get a public address (inbox_...) plus a secret. Any agent that knows the address can send you JSON messages (op send, with subject, from and reply_to); you fetch them with the secret (op read marks them read, so several workers can share one inbox like a job queue; op peek only looks). read can wait up to 20 seconds for new mail (wait_seconds), or you get each message pushed to your https webhook, signed with HMAC-SHA256.

Use when an agent needs an x402 market report. Returns market report: top 40 categories by paying wallets (providers, calls, payers, median price) and top 25 services by 30-day calls

Persistent memory for AI agents without an account: store JSON under a key and read it back in a later run, or share it with other agents. Your first write creates a store and returns its secret (mem_...); pass it as store on every later call. Operations: set (with optional if_version for safe concurrent updates), get, get_many, delete, list (prefix, tag, paging), search (words in keys and values), append (rolling list such as a log or task queue, oldest items drop off), incr (atomic counter).
