For Developers · Early access

Build on Piu. Model API, RAG, agents.

A developer surface for the platform — model selection, tenant-scoped document ingest, and programmatic agent creation. Standards-based. Isolated per tenant.

Model selection & hot-swap

Choose the model per tenant or per agent. Swap at runtime without rebuilding pathways or losing cohort context. Cost, latency, and capability trade-offs are yours to make.

Early access
POST /v1/tenants/{id}/model
{
  "provider": "anthropic",
  "model": "claude-sonnet-4-6",
  "fallback": "claude-haiku-4-5"
}

Tenant-scoped RAG ingest

Upload documents to your tenant's isolated vector index. Formularies, protocols, benefit rules, dietary standards — whatever Piu should ground its answers in. Chunking, embedding, and retrieval are managed.

Early access
POST /v1/tenants/{id}/rag/ingest
Content-Type: multipart/form-data

file: formulary_2026_q3.pdf
namespace: "benefits"
ttl: "90d"

Agent builder (no-code + API)

Build agents by describing them in plain language, or programmatically via the API. Supply reference docs, set guardrails, and deploy white-labeled under your brand. Guardrail validation runs before publish — human sign-off only if flagged.

Early access
POST /v1/tenants/{id}/agents
{
  "name": "Post-discharge CHF",
  "description": "Daily check-in...",
  "docs": ["proto_chf_v2.pdf"],
  "guardrails": "clinical_default",
  "publish": "draft"
}
