Send physical mail (letters and postcards) in the US via PostalForm using x402 USDC payments on Base from the awal agent wallet. Use when the user asks to send mail, post a letter, mail a document, send a postcard, mail a PDF, send physical mail, or "mail it to [someone]". Supports user-provided PDFs, auto-generation from text, and AI image generation for postcards via fal.ai (also paid with x402). Recipient must be in the US. Single recipient per send.
An X API alternative and Twitter API alternative on fetcher.sh — pay-per-call in USDC via x402, or prepaid credits with a Bearer key, no OAuth and no developer application. Use when the user wants to search X posts by keyword, hashtag, or advanced operators (from:, to:, since:, until:, min_faves:, filter:), scrape an X/Twitter profile by handle, pull a user's posts, replies, followers, or followings, fetch a single post with its replies or reposters, read an X List's members or posts, check trending topics by country, or search for X accounts by name. Also covers building an X data pipeline, social listening, competitor monitoring, hashtag tracking, or follower export without the official X API's pricing tiers or app-review process.
This skill should be used when the user asks to 'swap tokens', 'trade OKB for USDC', 'buy tokens', 'sell tokens', 'exchange crypto', 'convert tokens', 'swap SOL for USDC', 'get a swap quote', 'execute a trade', 'find the best swap route', 'cheapest way to swap', 'optimal swap', 'compare swap rates', or mentions swapping, trading, buying, selling, or exchanging tokens on XLayer, Solana, Ethereum, Base, BSC, Arbitrum, Polygon, or any of 20+ supported chains. Aggregates liquidity from 500+ DEX sources for optimal routing and price. Supports slippage control, price impact protection, and cross-DEX route optimization. Do NOT use for general programming questions about swap code, or for analytical questions about historical swap volume.

Check a citation against the registry of record instead of recalling it. Use this to verify that a DOI or a reference actually exists, to get the real title, authors, journal, year, licence, funders and citation counts behind a DOI, to find the DOI for a half-remembered paper title, to audit a bibliography or reference list before it ships, to resolve an ORCID iD to a researcher's employments, educations and recent publications, and to tell two same-named authors apart. Reach for it whenever an invented citation is the way the task fails — a fabricated reference reads exactly like a real one, with a plausible journal, plausible authors and a DOI of the right shape, and only the registry separates them. Crossref holds what publishers deposited and ORCID holds what researchers claim; neither is recallable from training data. Browsing, searching and dry runs cost nothing and need no wallet; a real call costs $0.003 to $0.004 in USDC on Base, with no signup, no API key and no gas.
The UTC offset, abbreviation and DST state a zone was on at any moment from 1970, with the surrounding transitions, and resolution of ambiguous or nonexistent local times. Called as GET /v1/tz/offset-at, it takes timezone, instant, localTime and returns timezone, utcOffset, isDst, resolution. An agent scheduling or reconciling timestamps must know that 01:30 on a fall-back night happens twice and 02:30 on a spring-forward night never happens at all; fixed offset arithmetic silently books the wrong hour. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.004, paid in USDC on Base over x402.
Generate CSPRNG bytes from the Web Crypto API, returned as hex, base64 or a UUID. Never Math.random. Called as GET /v1/crypto/random-bytes, it takes bytes, encoding and returns value, encoding. Observed on-chain demand: agents need unguessable nonces, tokens and idempotency keys, and a language runtime without a CSPRNG or a model asked to "pick a random number" both produce predictable output. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.
Convert an HTML document supplied in the request body to clean Markdown, stripping scripts and styles. Called as POST /v1/doc/html-to-markdown, it takes html and returns markdown, characters, inputBytes. A research agent handed raw HTML must reduce it to readable text before it can reason over it, and passing full markup through a model wastes most of the context window. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.004, paid in USDC on Base over x402.
Pulls DOIs, arXiv ids, PMIDs, PMCIDs and ISBNs out of free text, deduplicated and normalized, with the character offset of each first occurrence. Called as POST /v1/text/extract-citations, it takes text, kinds and returns count, citations, byKind. An agent handed a references section, an email or a PDF dump has to find the identifiers before it can look any of them up, and a model asked to do it by reading invents DOIs that resolve to nothing. The catalog already answers `crossref.doi-metadata` and `pubmed.citation-search`; neither could tell you what to ask them about. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.
Insert, delete, replace, extract, locate or measure at exact character offsets, counting by grapheme, code point or UTF-16 unit, with the affected range reported in both the chosen unit and UTF-16. Called as POST /v1/text/char-edit, it takes text, op, unit, index and returns op, unit, text, inputLength. Character-indexed string edits are a measured failure mode for language models (arXiv:2409.15452), and the index a model reasons about is rarely the index a runtime uses: a skin-toned emoji is one grapheme, two code points and four UTF-16 units, so an offset is wrong until the unit is named.

Score text from -1 (strongly negative) to +1 (strongly positive) with a label, handling negation, intensifiers and emphasis. Called as POST /v1/text/sentiment, it takes text and returns score, label, matches, positiveTerms. A support-triage or review-monitoring agent must decide whether a message is a complaint before it routes or escalates it, and a model call for one number costs more than this and is not reproducible.

Parses a BCP 47 language tag into language, extlang, script, region, variant, extension and private-use subtags, validates each against the IANA registry, and returns the canonical form. Called as GET /v1/lang/bcp47, it takes tag and returns valid, canonical, language, errors. Locale strings arrive from users, feeds and file names, and a wrong one silently mis-routes content rather than failing. Checking a tag properly means holding a 730KB registry and implementing the RFC 5646 grammar; almost nobody does either, so tags like en-UK and zh-CN-Hans ship broken.
