# canireach

> A behavioral access map of the agent web. We measure whether agents can reach the top 1000 domains, what stops them, and which sites publish a detour. Numbers are recomputed from published capture bytes; every capture is downloadable with its SHA-256.

Every figure on this origin comes from one named capture: `2026-08-22T0815Z` (`pre-2026-09-15-baseline`), observed 2026-08-22T08:28:13.633Z to 2026-08-22T08:40:54.831Z. This surface is pinned to the pre-2026-09-15 baseline so its published figures stay citable and stop moving. Captures after it were taken with a different instrument profile, so the difference between them is not all web. Every capture this project has published is downloadable with its manifest and SHA-256 from the releases page. Do not read these numbers as the state of the web today; read them as one dated measurement whose instrument profile is published beside it.

## Data

- [https://canireach.ai/api/summary.json](https://canireach.ai/api/summary.json): headline figures, per-caller reachability, affordance adoption, challenge vendors
- [https://canireach.ai/api/baseline.json](https://canireach.ai/api/baseline.json): the full derived aggregate for capture 2026-08-22T0815Z, with its manifest
- [https://canireach.ai/method](https://canireach.ai/method): measurement contract, rails, denominator discipline, comparability rules
- [https://canireach.ai/bot](https://canireach.ai/bot): what our probe is and how to block it

## Tools

- [https://canireach.ai/api/mcp.json](https://canireach.ai/api/mcp.json): MCP server descriptor — tool names, input schemas, invocation, and the fields an answer will never contain
- [https://canireach.ai/mcp](https://canireach.ai/mcp): reachability_lookup and dataset_status over stdio; ask what was last measured at a domain, through which door, and whether a detour was published. Read-only, no network, answers from hashed capture bytes
