How this service works
Short-burst authorize — Session Cert. Exact $0.25 → 10 Ed25519 PASS slots (~30m). For production jobs use Workday Pack POST /v1/workday. Burn /v1/session/cert → verify → execute. Not lint.
Output
Returns an Ed25519-signed session certificate granting 10 PASS slots valid for approximately 30 minutes, tied to the provided agent_id. The response includes the certificate type and an example object showing the issued credential. The agent can then use this cert on subsequent SQLGuard verify/execute calls during the session window.
Example use cases
Authorize agent before SQL batch run
“Create a SQLGuard session cert for my agent 'agent-7f3a9d' before I kick off the SQL validation jobs — I need the 10 execution slots for the next half hour.”
Pre-authorize agent for production SQL guard
“I need to authorize agent ID 'prod-agent-0042' with a fresh session certificate on SQLGuard so it can execute SQL guard checks in the next cycle.”
Obtain session token for CI pipeline agent
“Issue a 30-minute SQLGuard session cert for agent ID 'ci-pipeline-agent-88' so the pipeline can burn through its execution slots during the build run.”

Endpoint
POSThttps://sqlguard-io.fly.dev/v1/session?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to run a short burst of SQLGuard validate/verify/execute operations and requires an Ed25519 session certificate to authorize them. Prefer this over Instant or Prepaid Volume Credits when the task is time-bounded (~30 minutes) and fits within 10 execution slots. For longer production jobs requiring more slots, use the Workday Pack POST /v1/workday instead. This is not a linting endpoint — it issues authorization, not SQL analysis.
Side effects
- Missing or invalid agent_id results in a 400 validation error
- Payment of $0.25 USDC not received or x402 handshake fails — 402 Payment Required
- Session cert already active for this agent_id — may return conflict or overwrite
- Expired session slots — cert is only valid ~30 minutes; subsequent calls fail after window closes
- bodyType not set to a valid enum value (json, form-data, text) causes schema validation failure
- Network or Fly.dev infrastructure downtime returns 5xx errors
