Funding-source graph for a token: nodes are wallets, edges are first-funding relationships, labeled with exchange attributions where known.

Private web search for AI agents — zero logging, no tracking, no human signup required. Pay-per-query with USDC, no API keys or accounts. Multi-engine JSON results. Pass q=query, optional count (1-20), offset.

Batch spot prices for up to 20 assets in one call — each with price, 24h change and volume, keyed by symbol. The cost-efficient way to price a basket or portfolio in a single request instead of N calls.

Extract structured data from resume/CV text using Claude Haiku — returns name, contact info, skills, work experience, and education as clean JSON arrays so agents can automate applicant screening, candidate databases, and recruiting workflows from raw resume text.

Turn event fields into a valid RFC 5545 .ics calendar file — handles timed and all-day events, escaping, line folding, and a deterministic UID for idempotent re-import — so agents can publish events that import cleanly into Google, Apple, and Outlook calendars. Add ?download=1 (or Accept: text/calendar) to receive the raw .ics file with a Content-Disposition attachment header instead of the JSON envelope. Pure compu…

Detect the language of any text input using stopword-set matching and Unicode script analysis — returns the detected language, ISO code, a high/medium/low confidence level, and top alternative languages so agents can route multilingual content, trigger translation workflows, and classify text without a paid NLP API.

Fetch and parse any XML sitemap or sitemap index file — returns URLs with their priority, change frequency, and last modified date, follows sitemap indexes one level deep (first 3 child sitemaps), and auto-discovers the sitemap from robots.txt or common paths when given a bare domain — so agents can enumerate site content for crawling, indexing, and SEO analysis.

Per-provider digest. Pass the provider slug (anthropic, openai, google, etc.) as the URL path segment. Returns the model catalog scoped to that provider plus current pricing matrix, status incidents, and reliability summary. The single-call lookup an agent makes when it needs everything about a specific provider.

Top-N AI model recommendation for a task. Joins live pricing, benchmarks, provider status, and latency into a single composite score so an agent gets a ranked answer in one call instead of stitching three free endpoints together.

Raw on-chain registry event log for one autonomous AI trading bot: registrations, wallet links, pre-committed strategy attestations (missions), and challenges. The verifiable audit trail behind a bot's track record.

Leaderboard / ranking of autonomous AI trading bots, ordered by verifiable alpha vs a HODL 50/50 BTC+ETH benchmark. Each bot stakes USDC and pre-commits its strategy on-chain, so its track record and PnL are provable, not self-reported — built for agents deciding which bot to copy-trade or allocate to. Returns ranked bots plus registry-wide totals (stake, volume, trades).

Retrieve private company deal intelligence including funding rounds, valuations, investors, M&A activity, and ownership changes.

Returns network-wide totals: total x402 events, service count, and a UA classification breakdown (agent vs browser vs bot). Use it to benchmark your service's agent-traffic share against the network.

Document extraction: fetch a PDF, DOCX, or CSV by URL and get clean Markdown plus structured JSON — PDF text by page with metadata (honestly flags scanned PDFs that would need OCR), DOCX converted to real Markdown, CSV parsed to typed columns + JSON rows + a Markdown table.
