2s
2s ("the (most) everything API", 2s.io) is a pay-per-call REST API built for AI agents: 575 endpoints across 112 groups on one origin — US public records and government data, company and legal identifiers (GLEIF, OFAC, state registries), SEC filings, crypto and web3, security and CVEs, patents and case law, medical codes, weather and geocoding, ANSI X12 / EDIFACT EDI, an OpenAI-compatible AI gateway (chat, image, multi-model council) and wallet-scoped agent infrastructure (kv/doc/vector/blob store, locks, queues, schedules, pub/sub and 26 kinds of signed-callback watchers). There are no accounts and no API keys: every call is paid in USDC on Base or Solana through the x402 protocol (HTTP 402 → sign → retry), with a free trial call per endpoint per hour and actual-usage "upto" billing on AI endpoints. The same catalog is published as an OpenAPI 3.1.0 contract at https://2s.io/openapi.json, a remote MCP server at https://2s.io/mcp (plus the npx @2sio/mcp local server), an A2A 0.3.0 agent card whose one skill is endpoint discovery, an RFC 9727 API catalog, an APIs.json index, an llms.txt, an MCP server card, an x402 manifest and an ERC-8004 on-chain agent registration. Maintained by an individual operator (alley@2s.io); the SDK monorepo is github.com/2s-io/sdk.
2s publishes 114 API contracts indexed on the APIs.io network, including Agent API, Agriculture API, AI API, and 111 more. Tagged areas include Agents, Agentic Commerce, x402, MCP, and A2A.
The 2s catalog on APIs.io includes 1 event-driven AsyncAPI specification.
2s’ developer surface includes documentation, API reference, getting-started guide, pricing, changelog, support, authentication, and 28 more developer resources.

serverInfo 2s.io 1.0.0). initialize and tools/list answer anonymously with 575 tools — one per REST operation, named by
the spec's x-2s-id, each carrying a real inputSchema; resources/list and prompts/list are not implemented. Paid tool calls
are settled through x402 by a hosted signer that takes the caller's EVM private key in an X-EVM-Private-Key header, which
the provider's own docs recommend against in favour of the local stdio server, npx -y @2sio/mcp (npm @2sio/mcp 1.82.0),
that keeps the key on the caller's machine. Both accept a trial mode. A SEP-1649 server card is published at /.well-known/mcp/server-card.json.
