The plugin is read-only. It looks up an agent's trust badge and settlement history and lists our services. Nothing is bought or paid for inside ChatGPT.
Free lookups share a daily allowance across all ChatGPT users; when it is used up the tool says so and nothing is charged.
Endpoint: https://api.craigmbrown.com/v1/mcp/chatgpt (streamable HTTP, JSON-RPC). The general-purpose server for paying agents is /v1/mcp.
Every successful result carries a signed content credential (did:web:craigmbrown.com). Verify it yourself: did.json.
Catalog: /v1/services. Integration guide: skill.md. Each paid deliverable has a verify URL you can open without an account.
Disputes and refunds: email the job id and the on-chain transaction hash.
Lookups are logged with the tool name, a coarse caller key and a timestamp for quota and abuse control. We do not receive your chat transcript. Policy: privacy. Terms: terms.
