Public playground first, then an instant API key, then the SDK and MCP path into your actual production responses. The docs should feel like part of the product, not a sidecar.

On-ramp

Public proof before private integration.

Use the playground, leaderboard, and findings feed to understand the scoring language before you wire ABIS into your own model outputs.

PlaygroundLeaderboardFindings

Authentication

The API key is simple by design.

Public routes stay open. Protected scoring routes accept X-API-Key so teams can prove value fast and automate later.

Instant free key

Sign up with name, email, and password. Your API key is returned immediately.

Public surfaces first

Leaderboard, findings, and the playground are open so you can evaluate ABIS before integrating.

SDK preferred

Use the SDK for feature extraction and request packaging instead of calling the scoring API by hand.

SDK Quickstart

Use the SDK for the cleanest path into the full scoring pipeline.

Install
pip install abis-sdk
Fastest path
from abis import ABIS

abis = ABIS(api_key="your-api-key")

result = abis.score(model="gpt-4o", response="Your model response")
print(result.drift_score)
print(result.calls_remaining)
Session scoring
from abis import ABIS

abis = ABIS(api_key="your-api-key")

with abis.session(model="gpt-4o") as session:
    response = my_ai_call(prompt)
    scores = session.score(prompt, response)
    print(scores.behavioral_health)
    print(scores.entropy)

Authentication

The key model is deliberately simple.

Public endpoints like the playground, leaderboard, findings, and model pages do not require authentication. Protected scoring and usage routes use the X-API-Key header.

Header example
curl -H "X-API-Key: your-api-key" \
  https://abis-drift-monitor-production-b484.up.railway.app/usage/me

Key handling

  • Your free key is shown once after signup.
  • Store it in an environment variable or secrets manager.
  • Usage checks are exposed through /usage/me when the backend route is available.

Rate limits

Public pages stay open. API volume changes by plan.

The free tier is built to prove the scoring pipeline quickly. Once ABIS becomes part of your daily QA loop, the higher plans open the deeper monitoring and correction surfaces.
