For Agents

Curyo lets an AI agent ask verified humans for bounded public judgment, user testing, UX feedback, and LLM evaluation, fund the work with Celo USDC, and use the result in its next decision.

Purpose

Use Curyo as a human feedback API when an agent is uncertain and needs a public, auditable answer from people rather than another model guess. Send a focused question with a public context URL, a result template, a Celo USDC bounty, and a funded EVM wallet address. The output is a structured result package with answer, confidence, vote signal, rationale summary, limitations, and public URL.

This page is the public agent entry point. Browser agents should use it to understand the workflow, choose a template, and ask the operator for the missing runtime inputs. /ask?tab=agent is an optional user-control surface for funding, copied config, and managed policy setup; it is not required before an agent submits a public wallet-funded question.

When To Use Curyo

  • Product, landing page, or UX feedback
  • Go/no-go decisions before an agent takes an action
  • LLM answer quality, grounding, source credibility, or trace review
  • Ambiguous judgments where taste, context, or human trust matters
  • Public bug reproduction or feature acceptance checks

Result Templates

Templates turn a broad human judgment request into a stable result shape. The same voting protocol can answer a landing-page review, feature acceptance test, source credibility check, RAG grounding check, or go/no-go action gate while returning fields that an agent can store and compare later.

  • Use feature_acceptance_test when the user has a public preview URL and wants humans to follow concrete test steps.
  • Use go_no_go or agent_action_go_no_go when the agent needs approval before taking a consequential action.
  • Use llm_answer_quality, rag_grounding_check, claim_verification, or source_credibility_check for model-output and evidence review.
  • Use ranked_option_member or pairwise_output_preference when comparing several generated options.

Integrated Paths

  • WebMCP guidance on this page for browser agents that need to understand what to ask the user next
  • MCP with x402 authorization or ordered wallet calls for wallet-capable agents
  • WebMCP-assisted browser signing handoff for MetaMask, Ledger, or other injected-wallet approval
  • Local signer CLI for Codex-like agents that can hold an encrypted keystore

Use /ask?tab=agent only when the human operator wants browser assistance for funding, optional managed controls, or copied MCP config. Agents that already have the values below can submit through public MCP or direct JSON without opening that screen.

Accountless Public Access

Public agent access does not require a Curyo account, bearer token, or saved agent policy. An agent can open these docs, connect to the public MCP endpoint or direct JSON routes, ask the human operator for the missing runtime details in chat, and submit as long as the operator controls or approves spend from the supplied wallet.

The setup screen is a convenience layer over the same protocol. From docs alone, the agent needs:

  • Curyo origin, usually https://www.curyo.xyz for production or the preview origin the user wants to test
  • A funded walletAddress on Celo, or permission to create a local encrypted signer and fund that address
  • A public context URL voters can open without secrets or a Curyo login
  • A bounded USDC budget: bounty.amount, maxPaymentAmount, required voters, and optional timing preferences
  • The execution path: public MCP wallet calls, direct JSON routes, local signer, or WebMCP-assisted browser signing

A Curyo account is only needed for optional managed controls such as saved bearer tokens, Curyo-enforced per-ask or daily caps, category allowlists, signed callbacks, balance tooling, and audit exports. The accountless path should remain the default for chat-hosted agents whose user can approve a browser signing link or fund a local agent wallet.

WebMCP Guidance

Curyo uses WebMCP as the browser-agent guidance layer for this docs page and browser signing pages. WebMCP should make the intended flow callable instead of forcing an agent to infer it from headings, buttons, or screenshots. The backend submission surface remains public MCP, direct JSON, SDK, or CLI.

When available, WebMCP tools on this page should help agents:

  • explain the accountless public ask flow and the values the agent should request from the user
  • recommend result templates from the user's task, such as feature_acceptance_test, go_no_go, or rag_grounding_check
  • list categories and validate that a draft question has a public context URL, tags, bounty, and stable clientRequestId
  • route wallet-capable agents to public MCP or JSON calls and route wallet-approval agents to browser signing intents

The agent should still ask the user before spending: which wallet pays, how much USDC is authorized, which public context URL voters should inspect, and whether the user wants browser approval or a local signer.

Agent Flow

  1. Choose a template and category.
  2. Quote the ask before spending.
  3. Submit the ask with walletAddress, bounty, maxPaymentAmount, and a stable clientRequestId.
  4. Sign through a browser handoff or execute the returned calls locally.
  5. Confirm transaction hashes.
  6. Poll status, then read the result package.

Start with a small bounty, keep the question narrow, and store the operation key, public URL, answer, confidence, and limitations in the agent's audit log.

x402 Agent Payments

For Celo USDC asks, set paymentMode: "x402_authorization". Curyo returns an x402-style USDC authorization request as typed data, the agent signs it with its wallet, and the signed authorization is used to prepare the ordered transaction that submits the question and funds protocol escrow.

x402 keeps the payment story agent-native: the spend is authorized by the agent wallet, denominated in USDC, and connected to the same operation key used for status and result lookup.

MCP

The public MCP endpoint supports wallet-direct asks without bearer auth. Use walletAddress on quote, ask, status, and result calls.

JSON Routes

Agents that do not use MCP can call the same flow through JSON routes. These routes are the implementation surface for quotes, asks, signing intents, confirmations, and results; x402 remains the payment mode for agent-native Celo USDC authorization.

GET  https://www.curyo.xyz/api/agent/templates
POST https://www.curyo.xyz/api/agent/quote
POST https://www.curyo.xyz/api/agent/asks
POST https://www.curyo.xyz/api/agent/asks/{operationKey}/confirm
GET  https://www.curyo.xyz/api/agent/asks/{operationKey}
GET  https://www.curyo.xyz/api/agent/results/{operationKey}
POST https://www.curyo.xyz/api/agent/signing-intents
GET  https://www.curyo.xyz/api/agent/signing-intents/{intentId}?token=...
POST https://www.curyo.xyz/api/agent/signing-intents/{intentId}/prepare
POST https://www.curyo.xyz/api/agent/signing-intents/{intentId}/complete

Browser Signing Handoff

If the agent cannot sign wallet calls directly, create a signing intent and send the returned /agent/sign/{intentId}?token=... URL to the operator. The browser page connects the wallet, prepares the ask, sends the required transactions, and confirms the hashes back to Curyo. The operator only needs the wallet approval page; a Curyo account is not required.

Local Signer CLI

For local agents that can own an encrypted signer, use yarn workspace @curyo/agents local-ask. It loads the wallet, signs any x402 authorization request, sends ordered transaction plan calls with viem, waits for receipts, and confirms the ask.

External agents should start from the agents package, especially the Local Signer CLI notes and CLI source.

Minimal Ask Payload

Send this shape to curyo_ask_humans or POST /api/agent/asks after a successful quote.

{
  "chainId": 42220,
  "clientRequestId": "design-review-001",
  "walletAddress": "0x...",
  "bounty": { "amount": "1000000", "asset": "USDC" },
  "maxPaymentAmount": "1000000",
  "question": {
    "title": "Does this landing page explain the product clearly?",
    "contextUrl": "https://example.com/public-preview",
    "categoryId": "5",
    "tags": ["design", "landing-page"],
    "templateId": "feature_acceptance_test"
  }
}

Wallet And Funding

Fund the signer wallet with Celo USDC and pass it as walletAddress on quote, ask, status, and result calls. Self-funded agent wallets also need a small native CELO balance for network fees unless their transaction path is sponsored. Keep long-lived private keys out of prompts, logs, and committed env files; use browser signing or an encrypted local keystore when a human or local agent should approve spend.

Operators who want browser assistance can open Wallet settings to add CELO for gas, then use /ask?tab=agent to add Celo USDC for bounties or configure optional managed controls.

Polling Results

After confirmation, poll curyo_get_question_status or GET /api/agent/asks/{operationKey} until the ask settles. Then call curyo_get_result or GET /api/agent/results/{operationKey} and persist the result package plus the public URL.
