@everestan/protocolbanks-agent-tools

Tool definitions for the Protocol Banks Agent API — adapt once to the Vercel AI SDK, LangChain, OpenAI or Anthropic.

npm install @everestan/protocolbanks-sdk @everestan/protocolbanks-agent-tools

import { ProtocolBanks } from "@everestan/protocolbanks-sdk"
import { agentTools, toAnthropicTools, toOpenAIFunctions } from "@everestan/protocolbanks-agent-tools"

const pb = new ProtocolBanks({ apiKey: process.env.PB_KEY! })
const tools = agentTools(pb)
// agent_state · place_order · prepare_payment · prepare_swap · create_invoice

• Parameters are plain JSON Schema (OpenAI and Anthropic accept them directly via toOpenAIFunctions() / toAnthropicTools(); the Vercel AI SDK accepts them through jsonSchema(); LangChain wraps them in Zod).
• Only place_order executes. The other four return something the agent signs itself.
• Every tool returns the API envelope and the HTTP status. A 403 (key policy) or 409 (guard) is returned, not thrown, and the descriptions tell the model not to retry.
