How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://rag-diet.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok'), a data object, and an roi_proof containing the estimated compression_ratio_pct (e.g. 91.4%), indicating how much the context can be reduced before the full pipeline is invoked.
Example use cases
Pre-compression readiness check for agent
“Before I run the full AgentDiet compression on my data feed at https://news-api.example.com/articles, can you do a preflight check to confirm it'll work and show me the expected compression ratio?”
Validate POST request for context diet
“I want to preflight a POST request to https://my-rag-source.com/documents with AgentDiet to make sure the pipeline will accept it before I spend tokens on the full run.”
ROI estimate before token reduction job
“Can you do an AgentDiet preflight on https://longform-context.example.com/page to get the roi_proof and compression ratio so I know how many tokens I'll save before committing to the full diet?”
Technical details
Endpoint
GEThttps://rag-diet.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate a URL or HTTP request configuration before committing to the full AgentDiet context compression pipeline — especially to confirm compatibility and preview the expected compression ratio (roi_proof) without paying for the full distillation job. Prefer this over calling the main pipeline directly when you want to fail fast or estimate token savings upfront.
Side effects
- Invalid or unreachable URL returns error status
- Unsupported HTTP method (not GET or POST) causes schema validation failure
- Missing required 'input' object returns 400-level error
- URL parameter absent from queryParams when required
- Payment not settled in USDC on Base causes x402 payment failure
