Agents that fund themselves

An agent buys CREDIT, activates it, signs its own key and gets to work. No dashboard in the loop. An on-chain budget policy caps what it can spend and which grade it may use.

1 · Buy & activate (Solidity)

// USDG and CREDIT: 6 decimals.
exchange.getActivationQuote(usdgIn, maxFills);
usdg.approve(address(exchange), usdgIn);
bytes32 beneficiary = bytes32(uint256(uint160(agent)));
exchange.buyAndActivate(usdgIn, minCreditOut, beneficiary, maxFills);

// The agent names its operator once (from the agent wallet):
budget.setOperator(operator);
// Then the operator sets limits:
budget.setPolicy(agent, BudgetPolicy.Policy({
  dailyCapUsd6: 20_000_000,   // $20/day
  maxGrade: 2,                // 0 exact, 1 equivalent, 2 budget, 3 half
  allowedModelsRoot: 0x0      // optional merkle root
}));

2 · Sign a key & request (TypeScript)

import { Bestex } from "@bestex/agent";

const agent = await Bestex.agent({ wallet, chainId: 4663 });
// key = wallet signature of "Bestex API key · chain 4663 · epoch 0"

const res = await agent.run({
  task: "Refactor src/auth.ts and keep tests green",
  verify: { command: "npm test" },
  ceiling: "anthropic/claude-sonnet-5",
  grade: "verified",
});
console.log(res.chain);   // every hop: model, provider, pass/fail, cost
console.log(res.cost);    // what the agent was charged, in USD

await agent.transfer(workerAddress, 5);   // hand CREDIT to another agent

Teams of agents

A coordinator distributes CREDIT to workers as tasks emerge. Each worker activates what it needs and returns the rest.

Budget policy

Daily cap, max grade and allowed-model root live on-chain. The gateway reads them before every request; an agent cannot exceed what its operator set.

Balance

GET /v1/key returns balance and limits; every response carries x-bestex-balance. Charges land after the answer they pay for.
