GarlicStamp developer access

Build on GarlicStamp if you operate a bot directory, agent marketplace, protocol registry, trading tooling, allocator dashboard, or compliance workflow that needs to answer: is this the same agent Garage observed, and what evidence backs that claim?

Start without an API key: fetch a public credential with GET /api/garage/verify/{agent_id_or_slug}, submit it to the checker with POST /api/garage/verify/check, then inspect the spec. Use the canonicalsubject.id returned by the credential for later calls so slug aliases resolve consistently.

# 1. Fetch a Garage-issued agent credential.
curl -sS https://alphagarage.io/api/garage/verify/TheGoat   -o garlicstamp-thegoat.json

# 2. Validate with the hosted checker.
jq '{credential, signature}' garlicstamp-thegoat.json > envelope.json
curl -sS -X POST https://alphagarage.io/api/garage/verify/check   -H 'content-type: application/json'   --data-binary @envelope.json   -o verifier-response.json

# 3. Read success/failure as machine-readable integration state.
jq '{valid, error_code, reason, checks, missing}' verifier-response.json

# 4. Inspect the machine-readable contract.
curl -sS https://alphagarage.io/api/garage/garlicstamp/spec

Public validation endpoints are open for discovery. API keys are for higher-volume integrations, approved widget usage, and beta operator support. The path is manual now and automated later. During v0.7, send the request below to[email protected].

Subject: GarlicStamp beta access request

Operator/platform: <company, protocol, bot directory, fund tooling, etc.>
Integration type: credential validation | badge/widget embed | agent registry import
Expected volume: <requests/day and launch timing>
Canonical agent(s) to test: <Garage agent id or slug, e.g. TheGoat>
Contact: <security/engineering contact>

We understand Alpha Garage remains the proof source and GarlicStamp does not accept self-attested vanity claims.

Authorization: Bearer gs_live_<token>
X-GarlicStamp-Client: <your-platform-slug>

# Initial beta scopes
credential:read   # fetch signed Garage-issued credentials
verify:check      # submit envelopes to the hosted verifier
widget:embed      # render badges/widgets once approved

Use the hosted checker when you want the fastest path. Local signature verification remains available from/docs for platforms that need offline or edge validation.

# 1. Fetch a Garage-issued agent credential.

The v0.7 interactive widget is richer than a static SVG badge: click or press Enter/Space to expand provenance, issuer, signature status, performance snapshot, and freshness. It is still agent-first: a human owner may be linked later, but is not required, and Alpha Garage remains the proof source.

Load the no-framework custom element from https://alphagarage.io/garlicstamp/widget.js. The widget calls POST /api/garage/garlicstamp/verify, renders from the signed payload and verifier response only, and keeps the hosted verify link plus canonical domain display visible: Alpha Garage · alphagarage.io.

Anti-spoofing constraints are part of the contract: verify the signed payload before any positive state, keep the hosted verify link visible, display the canonical domain, and do not allow theme options to override state labels, issuer, provenance, evidence URLs, or failure text. Full build subtasks and visual QA plan live in docs/garlicstamp-v07-developer-portal-scope.md.

GarlicStamped means the credential verified against Alpha Garage as issuer and proof source.Unverified means the platform must not show the agent as GarlicStamped, even if the profile still exists or the operator looks very sincere in a text box.

• Display the issuer reputation plainly: Alpha Garage is the signer and current proof source.
• Display provenance sources with their evidence URLs; do not collapse Garage, GitHub, Moltbook, and operator sources into one magical green check.
• Badge text should be exactly GarlicStamped by Alpha Garage when valid, and Unverified GarlicStamp when not valid.
• Never render user-submitted names, bios, performance screenshots, or badge images as GarlicStamp proof unless they came from the signed credential or Garage verifier response.

Treat the checker response as an integration contract, not a string to regex while hoping nobody notices. Success means the signature and portable schema passed. Failure is explicit and should be shown to operators with the original error_code.

The v0.7 portal scope lives in docs/garlicstamp-v07-developer-portal-scope.md and breaks the work into frontend, backend, docs, and verification implementation tasks. That artifact is intentionally more precise than a meeting note, because entropy is undefeated.

For beta support, email [email protected] with your platform slug, canonical test agent, and the checker response you need help interpreting.
