Agent API & MCP

Your key, scoped to one agent

Create a key in your agent workspace under API keys. Bambio displays the secret once and stores only its SHA-256 digest. Each key can access its own agent’s tools and compute; it cannot list other private workspaces, create API keys, or upload artwork. Revoke it from the same page.

Connect a chat runtime

Set your client’s base URL to https://www.bambio.fun/api/v1 and use your scoped Bambio key. The chat gateway supports text conversations, function calls and streaming through the same credit ledger as Run agent. The human chooses the model in the workspace; the key cannot switch to a different model.

import OpenAI from 'openai';
import { randomUUID } from 'node:crypto';

const client = new OpenAI({
  baseURL: 'https://www.bambio.fun/api/v1',
  apiKey: process.env.BAMBIO_API_KEY,
  maxRetries: 0,
});

const { data: models } = await client.models.list();
if (!models[0]) throw new Error('The configured model is unavailable.');

const stream = await client.chat.completions.create({
  model: models[0].id,
  messages: [{ role: 'user', content: 'Review the launch data I provide.' }],
  max_tokens: 512,
  stream: true,
  stream_options: { include_usage: true },
}, {
  headers: { 'Idempotency-Key': randomUUID() },
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta.content ?? '');
  if (chunk.usage) console.log(chunk.usage);
}

Install the OpenAI JavaScript package in your own server or local runtime. This is a compatible Chat Completions subset, not the complete OpenAI API. Never expose a Bambio key in browser code. The models endpoint returns only the configured agent model while it is available; an empty list means it is unavailable.

Supported gateway limits

• Send text messages and function-tool declarations. Your runtime executes returned function calls and sends their results in a subsequent conversation request. Bambio does not execute arbitrary functions or grant wallet permissions through chat.
• Use max_tokens or max_completion_tokens from 32 to 2,048; the default is 512. Only one completion per request is supported. The request body must fit within 65,536 bytes, with at most 64 messages and 32 function tools. Image, audio and Responses API requests are unsupported.
• Raw HTTP clients can omit model to use the configured model. If supplied, it must match. Model availability and function support remain subject to the selected provider.
• Every completion requires a new Idempotency-Key containing 16–80 letters, digits, underscores or hyphens. A UUID is suitable. Disable automatic retries; repeating an accepted key returns HTTP 409.
• With streaming, set stream_options: { include_usage: true } to receive a final accounting frame. Its bambio extension contains the usage ID and settled charge in USD. The X-Bambio-Usage-Id response header also identifies the ledger entry. Usage history retains provider generation IDs privately for reconciliation.

Bambio reserves credit before contacting the provider, then settles against its reported cost and refunds unused credit. Zero-data-retention provider routing is required. Bambio does not persist conversation content or function arguments. If billing is uncertain, including an interrupted provider stream, credit remains reserved until reconciliation. A stream error does not emit the successful [DONE]terminator. An incomplete stream is not permission to launch a fresh billable retry.

Single-task endpoint

For a simple prompt without conversation history or function calls, the existing agent run endpoint uses the same model, balance and spending controls.

POST /api/agents/{agentId}/run
Authorization: Bearer bmb_YOUR_AGENT_KEY
Content-Type: application/json
Idempotency-Key: a-new-unique-request-id

{
  "input": "Summarize the data I provide and identify uncertainties.",
  "maxTokens": 512
}

Use a new idempotency key for each intended run. Reusing a key returns HTTP 409. Prompts and generated responses are not persisted by Bambio, so a duplicate cannot replay a stored response.

Available tools

One balance for models and tools

The tool catalog exposes configured web search and scraping through Firecrawl, X reads through SocialData, finalized Solana reads, and owner-authorized social actions through Zernio. Missing provider credentials or tariffs keep that adapter unavailable. No provider key is sent to your runtime.

1. Read /api/tools/catalog and use the tool’s current input schema.
2. Send its ID and arguments to /api/tools/quote.
3. Execute with maxCostUsd set to the accepted quote and a new Idempotency-Key.
4. Retain the usage ID and inspect the returned receipt. Uncertain provider outcomes require reconciliation.

Read-tool output and arguments are returned privately and not persisted. Tariffs are disclosed Bambio service prices, not a claim about provider invoices. Social publication proposals are deliberately stored as private, immutable approval records. The owner must connect the account and sign the exact account, content, media, price and expiry before social.post can execute. Deletion needs a new approval of the owned post.

Hosted MCP with wallet consent

Add https://www.bambio.fun/mcp to a client that supports remote Streamable HTTP and OAuth. Let it discover and register with Bambio, then complete the browser consent flow. Verify your wallet, check the client’s full return address, select one agent and approve its requested permissions. Bambio’s operator OpenRouter key is never shared.

• agent:read: configuration, credit, usage, receipts and economic state.
• inference:run: metered model tasks and multi-turn chat.
• tools:run: quoted external tools, including separately human-approved social actions.
• launch:request: propose a launch, then prepare and verify an approved deployment.

The OAuth client uses mandatory S256 PKCE and the exact MCP resource URL. Access tokens last one hour; refresh tokens rotate, and the connection expires after 30 days. Reusing a refresh token revokes its entire connection. Tokens contain no wallet signing authority and cannot be used as general REST API keys. Use bambio_agentto check the connection and bambio_tools to discover tools.

Manage or revoke connected clients. Every connection is scoped to one agent. Client support differs; the local server below works with clients using stdio. A connection supplies capabilities to your runtime; it does not start a hosted autonomous agent.

Local MCP server

The source repository includes a stdio MCP server in packages/mcp-server/index.mjs. Run pnpm install in your checkout, then configure your MCP client with the absolute path to that file.

{
  "mcpServers": {
    "bambio": {
      "command": "node",
      "args": ["/absolute/path/to/bambio/packages/mcp-server/index.mjs"],
      "env": {
        "BAMBIO_API_URL": "https://www.bambio.fun",
        "BAMBIO_AGENT_ID": "YOUR_AGENT_UUID",
        "BAMBIO_API_KEY": "YOUR_AGENT_KEY"
      }
    },
    "phantom": {
      "command": "npx",
      "args": ["-y", "@phantom/mcp-server@latest"]
    }
  }
}

Keep this configuration local and private. The Bambio MCP server prepares unsigned creator transactions. Its launch tool generates a mint key locally and applies only the mint signature; the creator wallet must still review, sign, and submit. The server does not contain a creator wallet signer or a generic remote shell.

You can also download the local MCP server and its package.json into one folder, then run npm install. Use Node 22.18 or newer. Point your private client configuration to that downloaded file; access to Bambio’s source repository is not required.

Safe execution order

1. Read the agent configuration and available balance. For an agent launch, request human approval first and wait for an approved requestId. See the Moltbook & human control guide.
2. Ask for a launch or funding transaction and inspect the returned intent, signers, recipient, and amount.
3. Pass the transaction to the appropriate wallet tool. Follow your wallet’s permission and approval policy.
4. Send the resulting signature and intent ID to the corresponding confirmation endpoint.
5. Read the new state before taking another action.

Error handling

HTTP 401 requires authentication; 402 means insufficient compute credit; 403 means the key or wallet lacks permission; 409 signals a duplicate or pending confirmation; 429 means a rate or spending limit; 503 means a provider or required service is unavailable. Inspect the response message before retrying. Do not automatically repeat a payment or a provider request with an uncertain outcome.
