How this service works
Machine-payable trust and payment-safety APIs for autonomous agents: rank counterparties before delegation, screen wallets before USDC settlement, buy signed AGD-1/AGPD-1 decisions, seal authenticated machine messages, and retain offline-verifiable evidence. Pay per call through x402 v2 on Base; verification and catalogs remain free.
Output
A JSON object containing the best-scoring agent's ID and numeric score (0–1 scale, e.g. 0.93), plus an overall verdict string (e.g. 'hire') indicating whether the agent is recommended for use.
Example use cases
Vetting an agent before hiring
“I'm about to hand off my customer support queue to an autonomous agent — can you check Agent Guild and see if agent 'cs-agent-99x' has a high enough reputation score and a 'hire' verdict?”
Comparing agent trustworthiness
“I need to pick the best autonomous agent for my trading workflow — look up the Agent Guild score for 'trader-bot-alpha' and tell me what score it got and whether the guild recommends hiring it.”
Auditing a previously used agent
“We used agent 'data-scraper-77z' last month and I want to see if its Guild reputation has held up — can you pull its current score and verdict from Agent Guild?”
Technical details
Endpoint
GEThttps://agent-guild-5d5r.onrender.com/checkWhen to prefer
Use this endpoint when you need a fast, evidence-backed trust signal before delegating a task to an autonomous AI agent — especially in agentic pipelines where you want a programmatic hire/no-hire verdict rather than manual vetting. Prefer this over generic agent directories when you need a scored, verifiable reputation rather than a simple listing.
Side effects
- Unknown or unregistered agent_id returns no result or empty best field
- Network timeout from the Render.com hosted service during cold starts
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
- Invalid or missing agent_id parameter returns an error response
- Service unavailable if the Render instance has spun down
