How this service works
[MCP: fetch_result] Targeted JSONPath extraction (query param mode) from cached context reference.
Output
A JSON object containing the pruned/extracted result payload keyed by the referenceId, a success status string, the referenceId echo, and a retrievedTokens count indicating how many tokens the fetched slice occupies.
Example use cases
Resuming long-running agent memory
“I ran an optimize_context job earlier and got back referenceId 'ref_abc9000' — grab that cached slim payload now so I can feed it into the next agent step without blowing the token budget.”
Multi-turn chatbot context retrieval
“My chatbot stored a compressed conversation summary with ContextSlim under referenceId 'ref_turn42' — retrieve it so I can inject it into the current LLM prompt as prior context.”
MCP tool result cache lookup
“A previous MCP tools/call returned referenceId 'ref_toolxyz' for a big API response — fetch just the pruned subset now so my agent only sees the 9-token result, not the full payload.”
Technical details
Endpoint
GEThttps://contextslim.friczero.com/fetchWhen to prefer
Use this endpoint when you have already called optimize_context (or an equivalent ContextSlim pruning step) and received a referenceId, and you now need to retrieve the cached slim payload for injection into an LLM context window. Prefer this over re-running the full optimize_context call when the payload is already cached, latency is critical, and you want to minimize USDC micropayment costs by reusing cached results.
Side effects
- Invalid or expired referenceId returns 404 or error status
- Missing required referenceId query parameter causes 400 bad request
- x402 payment not satisfied causes 402 Payment Required before content is served
- KV cache eviction may cause referenceId to no longer be valid
- Network timeout on fetch returns 5xx error
