Turn unstructured text into structured JSON matching a caller-supplied schema using Claude Haiku — the agent declares the fields and types it wants, and gets back populated JSON with values pulled from the text and coerced to the right types, so agents can structure any prose into the exact shape their pipeline expects.

Split text into overlapping chunks for RAG ingestion — by characters or words, with configurable chunk size and overlap. Deterministic (same input → same chunks), returns each chunk with its index and start/end offsets. No API key, no LLM. Pairs with /v1/embeddings for a full chunk→embed pipeline.

Instant text statistics — characters (with/without spaces), words, unique words, sentences, paragraphs, average word/sentence length, longest word, reading and speaking time. Deterministic, no LLM, no API key. For agents sizing content before summarizing, chunking, embedding, or posting. Pass text as ?text= (GET) or a JSON body (POST).

Reference registration/renewal/transfer pricing from a curated table of ~21 common TLDs — Mode A: price one TLD (typical register/renew/transfer cost + renewal-markup %); Mode B: price a name across all covered TLDs, sorted cheapest-first with cheapest/cheapest_premium picks. Reference prices, not live per-registrar quotes — for budgeting and spotting predatory renewal markups; TLDs outside the table return pricing:null.

Full profile for any ERC-20 token by contract address — name, symbol, decimals, supply from the chain itself, plus live price, liquidity, and volume from DEX data — Base and Ethereum, no API key. Holder count included; identity read on-chain so it can't lie or be rate-limited away. 10min cache; unlisted tokens return nulls with a no_dex_liquidity finding.

Translate many independent strings in one request — each with a caller ID preserved in the response — with per-item status, glossary and tone support, and partial success so one bad item never fails the batch, so agents can localize whole string tables in a single call.

Translate up to 2000 words between languages using Claude Haiku — auto-detects source, supports 30+ target languages, preserves formatting, for larger documents and articles. For short snippets use the cheaper /translate/short.

Translate text between languages — text translation API for short content: translate a sentence, chat message, or up to 500 words to English, Spanish, French, Chinese, or any of 30+ languages. Language translation with auto-detected source language, formatting preserved; returns the translation plus detected source. Machine translation via Claude Haiku for agents localizing content cheaply. For longer documents use /translate/long.

Translate structured content — JSON, HTML, Markdown, templates, UI strings — without breaking structure. Preserves keys, tags, markdown, URLs, emails, variables, placeholders, code blocks, and brand names, honors a caller glossary, and validates that no placeholder was dropped, so agents can localize app content safely.

Generate common typo and look-alike variations of a domain and check which are already registered — catches character swaps, omissions, additions, homoglyphs, and alternate TLDs so agents can detect typosquatting and brand-impersonation domains targeting a company.

Check a URL against URLhaus malware database and heuristic phishing pattern analysis — returns threat classification, malware family if known, threat confidence, and risk score so agents can screen links before following them or sharing them in automated workflows.

One call vets a URL end to end — traces its full redirect chain, checks it against the URLhaus malware database plus phishing heuristics, audits its security headers, and inspects its SSL certificate — concurrent with graceful partial-failure handling, so agents get a complete safety verdict before following a link.

Check username availability across 20+ social platforms and developer sites simultaneously — returns which platforms have a profile registered under that handle so agents can find people, verify identities, scout brand handles, or check name availability before registration.

OpenAI-compatible chat completions gateway — standard /v1/chat/completions path and request shape, model chosen in the body: any gpt-* chat model (not Claude/embeddings), each at its own price. Priced per model, $0.005–$0.65 per call in USDC via x402, no API key: POST unpaid and the 402 quotes your model's exact price. Supports response_format json_object. GET /v1/models (free) lists every model with its endpoint and price.

OpenAI-compatible text embeddings API — standard /v1/embeddings request shape: input as a string or a batch of up to 128 strings (64000 chars total on text-embedding-3-small, the default; 24000 on text-embedding-3-large). Flat $0.005 per call in USDC via x402, no OpenAI account or API key. Returns float vectors for RAG, semantic search, clustering, and dedup.

Native + USDC + custom-token balances for any wallet on Base, Ethereum, or Solana — with USD estimates — straight from public RPCs, no API key. Raw units as decimal strings plus formatted numbers; add up to 10 ERC-20 contracts via tokens=. 60s cache; an empty, never-used address is a real answer (zeros + no_activity_detected finding).

Counterparty due-diligence for any Base or Ethereum wallet — age, funding origin, USDC flow, activity pattern, and risk flags in one scored report. The domain-report of wallets: wallet age, first funder, in/out totals, distinct counterparties, 30d activity shape, contract-or-EOA, score + A–F grade. An empty or fresh wallet is a real answer (low score + flags). 5min cache.

Query the Internet Archive Wayback Machine to check if a URL has ever been archived, get the closest snapshot to a given date, retrieve the most recent capture, and return archival history stats — so agents can access historical web content, verify past content claims, and recover deleted pages.

Live weather + 3-day forecast for any city or lat/lon worldwide — temperature, feels-like, humidity, wind, precipitation, cloud cover, and a plain-language condition. Give a city name (geocoded for you) or coordinates. No API key, metric or imperial units. Pass params as query (GET) or a JSON body (POST).

Multi-day weather forecast for any city or lat/lon worldwide — up to 16 days of daily highs/lows, precipitation & probability, UV, sunrise/sunset, wind, and plain-language conditions, plus optional next-24h hourly. Give a city name (geocoded) or coordinates. No API key, metric or imperial. Pass params as query (GET) or a JSON body (POST).

Extract text from a web page or PDF as clean Markdown — 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 scraper / reader for article and main content. For JS-rendered or bot-walled pages a plain fetch can't read, use /exa/contents.

Fetch any URL and get the raw body back — JSON parsed, everything else as text — from safe server-side egress. For data APIs (ArcGIS, government/open-data portals, blob storage) that /web/extract's markdown conversion mangles. No API key, SSRF-guarded, billed only on a usable 2xx response. Pass url as ?url= (GET) or a JSON body (POST).

Web search for AI agents — one query in, ranked live results out (title, url, published_date, author, score, optional snippets). Neural + keyword modes, category/domain/date filters. For a direct answer use /exa/answer. Keyless x402, pay per call on Base or Solana.

Domain registration lookup, WHOIS via RDAP — registrar, registration and expiry dates, last-updated date, nameservers, and status flags from the authoritative registry, plus an actionability score so agents can assess domain trustworthiness, ownership, or availability risk.
