How this service works
GO-TO product for funded agents: Daily Agent Signal (POST /v1/signal_latest $0.03, /v1/signal_history $0.10, /v1/signal_delta $0.05). Signal is the flagship; supporting/legacy routes are demoted. Archive honesty: archive_day_count=6 — 6 stored dates from 2026-09-19 through 2026-09-27. Intraday revisions do not add archive days. Unpaid calls return HTTP 402. USDC on Base. Free discovery: /, /agents.md, /llms.txt, /skill.md, /.well-known/x402.json, /.well-known/mcp.json, /openapi.json.
Output
Returns a JSON object with three fields: 'ok' (boolean confirming the endpoint is live and responsive), 'brand' (always 'draconic21'), and 'product' (always 'signal_continuity'). A 402 error is returned if payment is missing or invalid.
Example use cases
Pre-flight check before daily signal pull
“Before you fetch today's draconic21 daily agent signal, run the signal continuity check first so I know the pipeline is healthy and we won't get a stale or broken result.”
Agent workflow liveness guard
“My automated agent runs every morning — can you add a step that hits draconic21's signal continuity check and only proceeds to pull the signal if the response comes back ok?”
Debugging a broken signal pipeline
“We haven't been getting clean signal data from draconic21 — can you call the signal_continuity endpoint right now and tell me whether it's returning ok=true so I can figure out if the feed is the problem?”
Technical details
Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/signal_continuity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that the draconic21 signal pipeline is operational before committing to a more expensive signal_latest ($0.03) or signal_history ($0.10) call. It is the cheapest way ($0.07) to confirm service liveness within the draconic21 ecosystem, though note that signal_latest may be preferred if you need actual signal data regardless.
Side effects
- HTTP 402 Payment Required — returned when USDC payment on Base is not included or invalid
- Service unavailable if the underlying Render.com host is cold-starting or offline
- Malformed request body may yield a 400 error
- Unexpected schema mismatch if the response omits required ok/brand/product fields
