How this service works
Automated 8-gate pre-flight readiness auditor for x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0 agent cards, OASF records, and ERC-8004 identity.
Output
Returns a JSON object with a status field ('ok'), a data object containing per-gate audit results for all 8 protocol checks (x402 v2, Dexter gas floor, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, OASF, ERC-8004, and related), and an roi_proof object including a compression_ratio_pct metric (e.g. 91.4%).
Example use cases
Pre-launch agent payment compliance check
“Before I go live, can you run the full 8-gate pre-flight audit on https://api.myapp.dev/agent-pay using GET mode and tell me whether it's ready for x402 v2 and IETF MPP payments?”
ERC-8004 identity readiness verification
“Audit https://identity.myprotocol.io/verify with a GET request to see if it passes the ERC-8004 identity gate and the A2A v0.3.0 agent card checks.”
MCP Streamable HTTP compatibility audit
“Check whether https://mcp.myservice.com/stream is compliant with MCP Streamable HTTP and OASF records — run the pre-flight audit in GET mode and show me the compression ratio and any gate failures.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/context-compress?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-standard compliance check across all major agent-payment and agent-identity protocols (x402, IETF MPP, ERC-8004, MCP, A2A, OASF) in a single call. Prefer it over manual per-standard validators when you want a consolidated pass/fail report with compression metrics before deploying or listing an agent service.
Side effects
- Target URL unreachable or times out — audit cannot complete
- Invalid or missing 'input' object with required type and method fields — returns validation error
- Unsupported HTTP method passed in enum — schema rejection
- Target endpoint returns non-standard headers that block gate checks
- Payment not received (x402 flow fails) — endpoint returns 402 before audit runs
