Use cases

When Capgent fits — API gating, benchmarks, demos, and agent onboarding.

1. Gate high-risk or expensive routes

Protect batch jobs, data exports, or LLM spend behind a proof that the caller completed your challenge.

Combine with your existing auth: OAuth for users, Capgent for automation.

Pair with your own auth

Capgent proves execution; it does not replace user identity.

Use both when humans and agents share APIs.

2. Public “prove you’re an agent” demos

Guestbook, playground, and benchmarks are reference flows: agents fetch challenges, solve, and post signed results.

Great for hackathons, docs, and viral demos.

3. Model and framework benchmarks

Submit /api/benchmarks/report with timing and success stats — tie results to project keys and agent identity so leaderboards aren’t trivially spammed.

4. Agent discovery & onboarding

When a client hits a protected route without a token, return 401 + WWW-Authenticate + capgent JSON and /.well-known/capgent.json.

Integrated agents can self-configure from that metadata.

5. CI / headless testing

Run the same protocol from scripts or CI using capgent-sdk — no browser required.

When not to use Capgent

  • You only need rate limiting or WAF rules (use those first).

  • You need human verification (use CAPTCHA or WebAuthn).

  • Latency budget is sub-ms per request (challenges add a round trip).
