Developer docs

Tenzro Labs Platform serves curated models from machines Tenzro Labs runs on the Tenzro Network. One account, one credit balance, one kind of API key — reachable three ways. Pricing is free on testnet.

Inference API

OpenAI-compatible model calls, routed to a healthy machine that reports serving the model and billed from your credit. Pricing is free on testnet.

Platform API

REST API for the catalogue, credits, orders, keys, plans and rentals — everything the Platform UI does.

https://platform.tenzro.xyz/api

MCP server

The same operations as tools for Claude, Cursor, VS Code and any MCP client, over Streamable HTTP.

Quickstart

1. Sign in and add credit on the Credits page.
2. Create an API key on the API keys page. Keep inference checked; add read and manage if the key should also drive the Platform API or MCP server.
3. Call a model:

shell

export TENZRO_API_KEY=tzl_...

curl https://api.tenzro.xyz/v1/chat/completions \
  -H "Authorization: Bearer $TENZRO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "qwen3.5-4b", "messages": [{"role": "user", "content": "Hello"}]}'

4. Check what it cost:

shell

curl https://platform.tenzro.xyz/api/credits -H "Authorization: Bearer $TENZRO_API_KEY"

Concepts

Term	Meaning
Identity	Your did:tenzro:human identity and wallet, rooted in your passkeys and created at sign-up. Tenzro Labs holds no keys.
Agent	An identity under yours (did:tenzro:machine:…), delegated by your passkey. You approve what it may do and spend on your Tenzro Labs account, and give it API keys.
API key	The primary identifier: it names the party calling — you or one of your agents — and everything else follows from it.
Machine	Where a model runs: a cluster of operators' nodes on the Tenzro Network that Tenzro Labs serves from, shown as one machine with its resources combined. Requests name it in machine; the default is tenzro-partner-cluster.
Operator	Who runs a machine: a node operator on the Tenzro Network that partners with Tenzro Labs, renting it capacity or serving its traffic on demand.
Credit	Tenzro Labs' own unit of account, backed by TNZO on the Tenzro ledger: 1 credit = 0.001 TNZO. Calls draw credits down. Either usable anywhere, or pinned to one machine. Not a currency.
Ticket	A code worth a fixed number of credits, like a gift card. Redeem it on any account.
Rental	A dedicated slice of a machine (GPU, vCPU, memory, storage) for a fixed number of hours, paid up front. No machine offers rentals on testnet.
Plan	A monthly subscription on one machine with included credit, a rate limit, and keys pinned to it. No machine offers plans on testnet.
Order	Anything you buy. Created unpaid, then paid through Stripe (card) or Bridge (stablecoin), where set up.

Conventions

Balances, limits and model prices are in credits (credits, *_credits): language models per million tokens, forecasting and image models per request. Only what you pay in fiat is in US dollars (amount_usd, price_usd). Times are ISO 8601 in UTC. Ids are opaque strings with a prefix (ord_, key_, subs_, rent_). The OpenAPI document is at /api/openapi.json.
