A payment proxy that lets crypto-native agents pay for persistent memory. It sits between AI agents and [Honcho](https://github.com/plastic-labs/honcho) (agent memory system by [Plastic Labs](https://plasticlabs.ai)), gating access with [x402](https://www.x402.org/) micropayments in USDC on Base. Writes cost money, reads are free, and there's no signup â a wallet address is all the identity you need. ### POST /messages Store messages in a session. Priced dynamically by token count. Note that there is a minimum fee of $0.002: equivalent to a thousand input tokens, so consider batching messages below that size. Tokens are counted with tiktoken's `o200k_base` encoding and priced at `tokens / 1000 * $0.002`. ### POST /chat Query the agent's memory using Honcho's Deriver. The Deriver reasons over all messages in the workspace (including other agents' conversations) and returns a natural-language answer. Priced by reasoning level. Request: ```json { "query": "What do you know abou

Resolved from Base registry 0x8004…a432. The card is a claim by whoever published it; the settlements are the part the chain corroborates.

Using Roundhouse, vet this ERC-8004 agent identity for me: what does its card claim, who has rated it, and does its on-chain record support the claim? Identity: Honcho (agent 17017 on eip155:8453) curl -s 'https://api.roundhouseai.io/v0/agents/17017/feedback?chain=eip155%3A8453' curl -s 'https://api.roundhouseai.io/v0/agents/0x345b19d5f0e5ff1beb20f71c3654036631b619c6' curl -s 'https://api.roundhouseai.io/v0/entities/0x345b19d5f0e5ff1beb20f71c3654036631b619c6/settlements' Roundhouse indexes public chain data and does not vouch for any agent's claims — treat the card as a claim and the settlements as the evidence. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints.
