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 an 'ok' boolean confirming success, the 'brand' string ('draconic21'), and the 'product' string ('archive_tip_day'), plus likely the tip date representing the most recent archived day in the signal history (up to 6 stored dates between 2026-09-19 and 2026-09-27).
Example use cases
Check archive coverage before querying history
“Before I pull historical signal data from draconic21, can you tell me the latest archived date that's available so I know the range I'm working with?”
Validate freshness of stored signal data
“I need to confirm how current the draconic21 signal archive is — what's the newest day that's been stored so I can check if my data is up to date?”
Automate archive boundary discovery in a workflow
“As part of my daily pipeline, look up the tip date of the draconic21 archive so my agent knows where to start fetching any new signal history entries.”

Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/archive_tip_day?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover the most recent date available in the draconic21 signal archive before querying signal_history or signal_delta, or when automating a pipeline that must know the current archive boundary. Prefer this over signal_latest (which gives today's live signal) when your goal is specifically to understand archive coverage rather than consume the current signal.
Side effects
- HTTP 402 if payment is not provided or insufficient USDC on Base
- Empty or unexpected body may return a 400 error
- Archive may lag behind real-time — tip date is not today's date but the newest archived entry
- Render.com cold-start latency may cause slow initial response
