Overview

2s.io — 575+ pay-per-call tools for AI agents

@2sio/mcp exposes 2s.io's 575+ paid endpoints to any MCP host. Every call is paid per request from a USDC-funded wallet using the x402 protocol, settled on Base or Solana — no accounts, no API keys, no signup.

Why

More ground-truth data than any other x402 API. Public records, SEC filings, crypto & web3, security & CVEs, legal, medical, weather, geo, B2B/EDI — post-training-cutoff and continuously refreshed. Every response carries the upstream source (provider, URL, license): USPTO, SEC EDGAR, Congress.gov, openFDA, NHTSA, NWS, NOAA, USGS, US Census, OFAC, CourtListener, GLEIF, arXiv, PubMed, Wikipedia, and many more.
A full AI gateway. Chat, image generation, and multi-model consensus (ai.council) across every major model on one endpoint — priced per request in the 402 before you pay.
Agent infrastructure, no account needed. Wallet-scoped storage (kv / docs / vector search / private files), distributed locks, SQS-style queues, scheduled callbacks, pub/sub, and watchers — arm one and 2s pushes you a signed webhook when a wallet moves, a stock crosses a price, an SEC filing lands, a flight status changes.
upto billing (2s exclusive). AI endpoints also accept the x402 upto scheme: authorize the quoted worst-case, get settled only for your actual usage — a real on-chain call authorized $0.0549 and settled $0.0013. Exact-scheme calls work unchanged.
Cheap + verifiable. Prices from $0.001/call, quoted before you pay, settled on-chain in ~2 seconds with the tx hash in the response.

Try before you buy

Run with --trial (or TWOS_TRIAL=1) for one free real call per endpoint per hour — no wallet needed.

Concordance

@matharrismma

Language models generate; Concordance verifies. The verify tool checks a claim deterministically (no model in the loop) and returns HOLDS / BROKEN / INCOMPLETE with the worked reasoning and a sealed receipt (content_hash + cite_url) that re-fetches byte-identical or not at all. Also: ranked search over an ~11k-record library, seal_fetch to re-verify any receipt, redact to strip PII before text travels, and a sealed connection graph. Runs sovereign/offline too (stdlib-first Python). A public false-positive benchmark covers every domain: the engine has never sealed a falsehood. 38 tools live; remote endpoint at https://narrowhighway.com/mcp.
