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' or error), a data object containing per-gate audit results, and an roi_proof object including a compression_ratio_pct indicating how much the payload was compacted. Failed gates include specific error details for remediation.
Example use cases
Pre-launch agent endpoint compliance check
“Before I deploy my new A2A agent card, can you run it through the 8-gate pre-flight auditor to check x402 v2, MCP Streamable HTTP, and OASF readiness? Here's the JSON config I want to validate: {"agent":"mybot","version":"0.3.0","endpoint":"https://mybot.agentdiet.dev","method":"GET"}”
ERC-8004 identity readiness verification
“I need to confirm my ERC-8004 identity setup and Dexter gas floor config are ready before going live — can you audit this JSON and tell me which gates pass or fail? The raw JSON is: {"identity":"0xABC123","chain":"base","method":"POST"}”
Malformed JSON repair before protocol audit
“My LLM output produced broken JSON with trailing commas and I need it fixed AND checked against the IETF MPP and x402 v2 standards — can you repair and audit this: {"type":"http","method":"GET","fee":0.002,}”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/json-fix?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call multi-standard compliance check across x402 v2, ERC-8004, IETF MPP, MCP Streamable HTTP, A2A v0.3.0, and OASF simultaneously, rather than auditing each protocol separately. It is also appropriate when input JSON needs repair before auditing, combining JSON fixing and readiness validation in one pass.
Side effects
- Missing required 'input' object returns a schema validation error
- Invalid or unparseable raw_json causes a parse failure response
- Unsupported HTTP method (not GET or POST) is rejected by the enum constraint
- Network timeout or upstream unavailability returns a non-200 status
- Payload too large may be rejected or truncated silently
