aid: s1-dev name: Search1API description: Search1API is web access infrastructure for AI agents, operated by SuperAgents, LLC (Delaware). One credit-metered REST API at api.search1api.com provides multi-engine web search (Google, Bing, DuckDuckGo, Yandex, GitHub, arXiv, Reddit, X, Baidu and more), agentic search routed by the TypeSafe Jev model, news search, page crawling, screenshots, sitemap discovery, trending topics, structured extraction and asynchronous deep crawls. The same account reaches it through an OpenAPI 3.1 contract, official TypeScript and Python SDKs, the s1 CLI, a hosted OAuth 2.1 MCP server at mcp.search1api.com, an Agent Skill, and pay-per-request MPP/x402 payment challenges. url: https://raw.githubusercontent.com/api-evangelist/s1-dev/refs/heads/main/apis.yml x-type: company x-source: harvest:monid-connectors x-tier: profiled x-tier-reason: enrichment pass 2026-10-07 (local-v5; was harvest) specificationVersion: '0.20' created: '2026-10-07' modified: '2026-10-07' tags: - Company - Search - Web Search - Crawling - Web Scraping - News - AI Agents - MCP - Agent Tools - Data Extraction - Screenshots maintainers: - FN: Kin Lane email: kin@apievangelist.com - FN: APIs.json email: info@apis.io image: https://s1.dev/og-home-v2.png common: - type: AgentSkill url: skills/_index.yml - type: AgenticAccess url: agentic-access/s1-dev-agentic-access.yml - type: RateLimits url: rate-limits/s1-dev-rate-limits.yml - type: Plans url: plans/s1-dev-plans-pricing.yml - type: Spectral url: rules/s1-dev-rules.yml - type: JSONLD url: json-ld/s1-dev-context.jsonld - type: Vocabulary url: vocabulary/s1-dev-vocabulary.yml - type: DataModel url: data-model/s1-dev-data-model.yml - type: CLI url: cli/s1-dev-cli.yml - type: ChangeLog url: changelog/s1-dev-changelog.yml - type: Conventions url: conventions/s1-dev-conventions.yml - type: Authentication url: authentication/s1-dev-authentication.yml - type: OAuthScopes url: scopes/s1-dev-scopes.yml - type: Deprecation url: https://s1.dev/docs/changelog - type: Lifecycle url: lifecycle/s1-dev-lifecycle.yml - type: ErrorCatalog url: errors/s1-dev-problem-types.yml - type: Conformance url: conformance/s1-dev-conformance.yml - type: Overlay url: overlays/s1-dev-openapi-overlay.yaml - type: LLMsTxt url: llms/s1-dev-llms.txt - type: ToolCrosswalk url: mcp/s1-dev-tool-crosswalk.yml - type: MCPServer url: mcp/s1-dev-mcp.yml - type: WellKnown url: well-known/s1-dev-well-known.yml - type: Hosts url: hosts/s1-dev-hosts.yml - type: Vendors url: vendors/s1-dev-vendors.yml - type: SDKs url: packages/s1-dev-packages.yml - type: Packages url: packages/s1-dev-packages.yml - type: Sandbox url: https://app.s1.dev/playground/ask - type: Website url: https://s1.dev - type: DeveloperPortal url: https://s1.dev/docs - type: Documentation url: https://s1.dev/docs - type: APIReference url: https://s1.dev/docs/basic/search - type: GettingStarted url: https://s1.dev/docs/get-started/quickstart - type: About url: https://s1.dev/about - type: Support url: https://s1.dev/contact - type: Blog url: https://blog.s1.dev/ - type: ChangeLog url: https://s1.dev/docs/changelog - type: ChangeLog name: Product changelog (blog) url: https://blog.s1.dev/changelog - type: GitHubOrganization url: https://github.com/superagents-lab - type: GitHubOrganization name: Founder GitHub (linked from s1.dev) url: https://github.com/fatwang2 - type: Pricing url: https://s1.dev/pricing - type: Login url: https://app.s1.dev/ - type: SignUp url: https://app.s1.dev/sign-up - type: TermsOfService url: https://blog.s1.dev/pages/terms - type: PrivacyPolicy url: https://s1.dev/privacy - type: StatusPage url: https://status.search1api.com/ - type: DomainSecurity url: security/s1-dev-domain-security.yml apis: - aid: s1-dev:search1api-mcp-server name: Search1API MCP Server description: >- Official hosted Streamable HTTP MCP server exposing search, news, crawl, sitemap and trending tools to any MCP client, with OAuth 2.1 (PKCE, dynamic client registration via clerk.s1.dev) or a Search1API API key.
