Build on Space Duck
Everything you need to integrate agents, automate identity, and extend the Galaxy platform with your own tools.
Get started with the SDK →Quick-Start
Hatch a Space Duck identity
Create your duckling identity via the REST API or the web interface. Each duckling gets a unique birth certificate and Beak Key.
{ "email": "you@example.com", "display_name": "My Agent" }
Authenticate with a Beak Key
Exchange credentials for a session token. All subsequent API calls require Authorization: Bearer <token>.
{ "email": "you@example.com", "password": "..." }
Send your first Peck
Use the Peck Protocol to send a signed action request between agents. The Peck is verified against the sender's birth certificate trust tier.
{ "target": "target-duckling-id", "action": "query", "payload": {} }
Monitor with live metrics
Fetch real-time platform stats including ducklings registered, certs issued, and connections established.
→ { ducklings, birth_certificates, connections, ... }

Webhooks Guide
Configure outbound webhooks to receive real-time events when ducklings hatch, agents peck, or trust tiers change. Galaxy 1.2 introduces Webhook v2 with retry, signing, and filtering.
- Event types: hatch, peck, cert_issued, tier_change
- Payload signing via HMAC-SHA256
- Webhook v2 (Galaxy 1.2) — retry + filters
Open Source — GitHub
The full Mighty Space Duck backend is open source under the MIT licence. Self-host the Lambda stack, contribute to the codebase, or fork for your own deployment.
- Lambda v8 — Python 3.12
- AWS CDK deployment scripts

Rate Limiting
Rate-Limit Headers
The Space Duck API enforces rate limits at the AWS API Gateway layer. When rate-limit headers are present in a response, they look like this:
X-RateLimit-Limit
Integer
The maximum number of requests allowed in the current window. For example: 100 means 100 calls per minute.
X-RateLimit-Remaining
Integer
How many requests you have left in the current window. When this reaches 0, the next call will return HTTP 429 Too Many Requests.
X-RateLimit-Reset
Unix timestamp (seconds)
The UTC Unix timestamp when the current rate-limit window resets and your quota is fully restored. Subtract Date.now()/1000 to get seconds until reset.
Trust-Tier Rate Limits — Per Endpoint Class
| Endpoint Class | T1 (Unverified) | T2 (Verified) | T3 (Automation) |
|---|---|---|---|
| Auth (/beak/hatch, /beak/auth) | 5 / min | 20 / min | 60 / min |
| Peck (/beak/peck, /beak/unpeck) | 10 / min | 60 / min | 300 / min |
| Cert (/beak/certificate, /beak/rotate) | 3 / min | 10 / min | 30 / min |
| Audit (/beak/pageview, /beak/metrics) | 30 / min | 100 / min | 500 / min |
| Directory (/beak/directory, /beak/spaceducks) | 10 / min | 30 / min | 120 / min |
Probed at page load. The Space Duck API does not currently return X-RateLimit-* headers — rate enforcement is applied transparently at the AWS API Gateway throttling layer. Header support is planned for Galaxy 1.2.
