Seisoai

Base URL: https://seisoai.com Primary endpoint: POST /api/gateway/invoke/{toolId} or POST /api/gateway/invoke with toolId in body. Auth: X-API-Key or x402 payment (USDC on Base).

Agent-First Workflow (Do This Every Session)

1. Discover live tools:
   • GET /api/gateway/tools
2. For selected tools, fetch exact schema:
   • GET /api/gateway/tools/{toolId}
3. Optionally pre-price inputs:
   • GET /api/gateway/price/{toolId}
4. Invoke with API key or x402.
5. If queue tool, poll job status/result URLs from response.

Do not rely on static tool lists when a live registry is available.

Auth Strategy

Use this decision order:

1. If you have a project API key, use X-API-Key.
2. If you do not have a key, use x402 pay-per-request.
3. Do not send browser CSRF tokens for machine clients.

API Key Example

POST /api/gateway/invoke/image.generate.flux-2
X-API-Key: sk_live_xxx
Content-Type: application/json

{"prompt":"a sunset over mountains"}

x402 Example (2-step)

1. Call without payment header.
2. Receive 402 with payment requirements.
3. Sign/pay on Base.
4. Retry same request with one of:
   • payment-signature
   • x-payment
   • payment

High-Value Endpoints

• Discovery:
  • GET /api/gateway/tools
  • GET /api/gateway/tools/{toolId}
  • GET /api/gateway/price/{toolId}
  • GET /api/gateway/mcp-manifest
• Invoke:
  • POST /api/gateway/invoke/{toolId}
  • POST /api/gateway/invoke
• Jobs:
  • GET /api/gateway/jobs/{jobId}?model=...
  • GET /api/gateway/jobs/{jobId}/result?model=...
• Agent-scoped:
  • GET /api/gateway/agents
  • GET /api/gateway/agent/{agentId}
  • POST /api/gateway/agent/{agentId}/invoke/{toolId?}
  • POST /api/gateway/agent/{agentId}/orchestrate

Agent-Scoped Safety Controls (Mandatory)

Default posture: deny by default for agent-scoped routes.

Use agent-scoped endpoints only when all checks pass:

1. Explicit task requirement
   • Do not call /agent/* routes unless the current task explicitly requires operating a specific agent.
2. Exact agent binding
   • Resolve agentId from a trusted source (GET /api/gateway/agents or user-provided exact ID).
   • Never infer or guess agent IDs from names/prompts.
3. Authorization boundary
   • Use only the current caller credentials.
   • Never attempt to reuse, escalate, or proxy credentials to access other tenants/owners.
4. Single-agent scope
   • For one task, operate on one approved agentId unless the user explicitly requests multi-agent execution.
5. Tool allowlist enforcement
   • Before invoke/orchestrate, fetch GET /api/gateway/agent/{agentId} and only use tool IDs declared for that agent.
   • Reject tool IDs not listed in that agent definition.
6. No recursive orchestration
   • Do not create self-referential orchestrations, orchestration loops, or fan-out patterns across unknown agents.
7. No broad discovery exfiltration
   • Do not enumerate all agents unless needed for user task; prefer direct lookup when agentId is known.
8. Audit trail requirement
   • Log agentId, route, tool ID, and reason for each agent-scoped call in agent run notes.
9. On mismatch or ambiguity: stop
   • If ownership/scope/tool authorization is ambiguous, do not call /agent/*; fall back to /api/gateway/invoke.

Text->video:

{"prompt":"...","duration":"6s"}

DreamActor motion transfer:

{"source_image_url":"https://...","driving_video_url":"https://..."}

Voice clone TTS:

{"text":"...","audio_url":"https://..."}

3D image->mesh:

{"image_url":"https://...","output_format":"glb"}

Queue Handling Contract

If executionMode is queue, response includes job metadata. Use:

1. statusUrl until completed/failed.
2. resultUrl when completed.

Treat queue submit success as billable success (x402 settlement/API-key credit deduction already handled server-side).

Error Policy

• 400: Schema/input mismatch. Re-fetch tool schema and correct fields.
• 402: Missing/invalid payment or insufficient API key credits.
• 404: Tool/agent not found. Refresh registry.
• 503: Tool disabled. Select fallback in same category.
• 500: Retry with backoff; then switch model/tool.

Reliability Rules for Agents

1. Always discover live tools before planning multi-step flows.
2. Use exact schema from GET /tools/{toolId} for required fields.
3. Keep one tool call per request; chain in your agent.
4. Prefer explicit model/tool IDs over natural-language routing assumptions.
5. For retries, do not reuse stale x402 signatures.
6. Treat /api/gateway/agent/* as privileged routes and apply the mandatory safety controls above.

Self-Maintenance

When this file is updated:

• Keep IDs aligned with backend/services/toolRegistry.ts.
• Update last_synced and version.
• Keep examples minimal and executable.
