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 indicating success, a 'brand' string identifying the draconic21 service brand, and a 'product' string naming the specific signal product compared. Useful for confirming offer identity and routing decisions before committing to paid signal calls.
Example use cases
Choosing the right signal tier
“Compare the draconic21 signal offers for me — I want to know the brand and product details so I can decide whether to use signal_latest at $0.03 or signal_history at $0.10 for my trading bot.”
Validating offer metadata before purchase
“Before my agent starts paying for signals, can you run a compare_offers check on draconic21 and confirm what brand and product name gets returned so I know we're hitting the right service?”
Auditing available agent signal products
“Pull the draconic21 compare_offers result and list out the ok status, brand, and product so I can document which signal products are available for our funded agent fleet.”
Technical details
Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/compare_offers?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to compare or identify available signal products from draconic21 before committing to paid per-call signal endpoints. Prefer it over calling signal_latest or signal_history directly when the goal is discovery or validation of offer metadata rather than consuming actual signal data.
Side effects
- HTTP 402 if USDC payment on Base is not provided or insufficient
- Malformed request body returns 400-level error
- Service unavailable on Render cold starts causing timeout or 503
- Empty or missing required body fields may return error or empty comparison result
