MCP server exposing 1,000+ pay-per-call API endpoints across agent infrastructure (memory, coordination, secrets, verification), data, compute, finance, weather, geography, and reference categories — payments via x402 protocol in USDC on Base.

x402-gated data API (Cloudflare Worker) plus an MCP server wrapper serving aggregate weekly stats from the aijobsboom.com skilled-trades job board — trade counts, perk flags, scrub-rule counts. $0.01/$0.10 USDC per call, no raw job listings.

Bitcoin, Ethereum and 22 more coins: news sentiment scores from 9 crypto news outlets plus the Fear & Greed Index, with the headlines behind each score. Hourly sentiment history for research and backtesting. Three free tools need no wallet; live readings cost $0.01 and hourly history $0.05 per call, paid in USDC on Base via x402. Unsupported coins and no-news results are refused and not charged.

Lets any MCP client call SWARM's live services — GitHub code-health scans, researched summaries and reports, and everyday utilities — paying per call in USDC on Base with no account or API key. Payments are metered by a spend cap and only settled after the work succeeds.

Enables AI agents to pay USDC per call for Asia market intelligence data via HTTP 402 protocol, no API keys or subscriptions required.

Enables AI agents to perform corpus analysis tasks such as discovery, search, and data access via the Model Context Protocol.

Provides local, evidence-aware research memory with human review, revision history, and an inspector, allowing assistants to preserve source reports, inferences, assumptions, and evidence across sessions.

Enables running the same prompt(s) across roughly 300 models from Anthropic, OpenAI, Google, Meta, Mistral, DeepSeek, Qwen and others, then comparing per-model outputs, latency, token usage, error rates and billed cost side by side. Supports free cost estimates before launching, asynchronous run creation with status polling and cancellation, prepaid x402 credit top-ups, and an optional AI-written comparison summary of the results.

Provides access to ancient text corpora via stdio, enabling corpus listing, status checks, searching, and text/metadata retrieval with provenance envelopes.

Compress OCR-heavy PDFs into dense packed images so agents can work with long visual documents.

Provides source-grounded Christian research material with exact passages, provenance, and stable citations via a REST API.

Provides provenance-aware access to selected Sefaria Bible context, including Targumim, Mishnah, Jewish commentary, Josephus/Philo, and lexicon lookups, with on-demand caching of long-tail Sefaria texts.
