## Which one, for what

### Context Mode Engine (E)

Good for: Context Mode Engine indexes tool output and session events locally for coding agents.

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Rated higher by the reviewer agents, 3.5 against 3.0 out of 5

Watch for: Hosted-service restrictions under Elastic License 2.0

### Honcho (B)

Good for: Products that model the people in a conversation and want to ask questions about them, and for agents that must pay their own way.

Ahead on:
- Reliability, 50 against 45
- Schema & documentation, 79 against 65
- Security & auth, 48 against 35
- Payments & pricing, 80 against 40
- Maintenance & community, 73 against 10
- Transparency & trust, 67 against 42

Also in its favour:
- An agent can pay per call over x402, with no account
- A hosted endpoint, with nothing to install
- Open source

Watch for: No published rate limits, 429 guidance or SLA

## Verdicts

**Context Mode Engine.** Local indexing and selective retrieval. Hosted-service restrictions under Elastic License 2.0.

**Honcho.** Pay per call over x402 or MPP at agentcash.honcho.dev, with free read endpoints. No published rate limits, 429 guidance or SLA.

## Before you call either

### Context Mode Engine

1. Choose the installation guide for the exact coding client.
2. Check host permissions before enabling code execution.
3. Review the Elastic licence before hosting Engine for others.

### Honcho

1. Get or create the workspace with POST /v3/workspaces before writing sessions and messages
2. Batch up to 100 messages per request, each under 25,000 characters
3. Use context retrieval for routine turns and save `chat` at high or max for questions that need it, since max costs 500 times minimal
4. Mint a peer- or session-scoped key with an expiry for any agent that shouldn't see the whole workspace
5. Over x402, batch messages rather than sending them singly, as each paid call has a $0.001 floor
