Price API for AI agents (API-first)

Key public endpoints (typically no API key)

Use absolute URLs when configuring agents. These paths return JSON or plain text, not gated HTML dashboards.

• https://agentshare.dev/openapi.json — OpenAPI 3 (agent-facing paths)
• https://agentshare.dev/llm.txt — LLM-oriented discovery (mirrors under /llms.txt, /api/llm.txt)
• https://agentshare.dev/llms-full.txt — Markdown outline derived from OpenAPI
• https://agentshare.dev/agent.json — agent discovery (/.well-known/agentshare.json identical)
• https://agentshare.dev/mcp.json — MCP server directory JSON
• GET https://agentshare.dev/api/v1/meta — capabilities & live sources summary
• GET https://agentshare.dev/api/v1/agent-capabilities — compact capabilities
• GET https://agentshare.dev/api/v1/health — liveness probe
• GET https://agentshare.dev/coverage — data-domain coverage specification
• https://agentshare.dev/.well-known/discovery.json — compact URI pointer map

Sign up & free tier

1. Register: POST https://agentshare.dev/api/v1/auth/register with JSON body {"email":"…","password":"…"} (password minimum 8 characters).
2. The response includes your API key once—store it safely.
3. Free-tier keys typically receive on the order of 100 requests per calendar month (exact quota may evolve; pricing page is authoritative).
4. Send X-API-Key: <key> or Authorization: Bearer <key> on paid routes and on MCP Streamable HTTP.

For assistants and automated fetch tools

If a client fetched only HTML from this homepage, it still misses the canonical machine links listed above. You can repeat GET https://agentshare.dev/ with header Accept: application/json to obtain the same discovery summary as JSON (Vary: Accept). No JavaScript required—this pattern works for crawlers and “web fetch” style connectors in general.

A tiny “heartbeat” from recent agent traffic — designed for humans. No raw queries, IPs, or keys.

Curated MCP registry (sample)

Curated, editor-reviewed MCP registry for data, operations, and commerce-adjacent tools—built to pair with AgentShare price and offer APIs, not as a generic open directory.

GET /api/v1/registry/entries — verified listings

• Packrift MCP — Data & commerce · MCP
• AgentShare — Real-time Price & Offer MCP — Data & commerce · MCP
• Analytics & event pipeline (pattern) — Analytics

Data coverage (honesty)

GET /coverage separates focus categories versus beta/expanding scopes.

Live data sources

Every response surfaces its origin via source (per offer) and accesstrade_live / freshness_status (per response). The machine-readable summary is at GET /api/v1/meta → sources; see also GET /coverage for the focus map.

Additional leading marketplaces will be connected when partnerships and policy allow. We never claim coverage we do not actually serve — missing scope returns status: no_data with a precise reason instead of fabricating an offer.

Representative authenticated REST routes

Authenticated with API key (X-API-Key).
