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
