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 indicating whether the agent is funded and eligible to proceed, including an 'ok' boolean, the brand name, and the product name associated with the account.
Example use cases
Pre-flight funding check
“Before I trigger today's signal fetch, check whether my draconic21 agent wallet has enough budget to cover the call.”
Agent bootstrap validation
“When my agent starts up, verify it has sufficient USDC budget on draconic21 before it tries to pull any paid signal data.”
Graceful failure prevention
“Check my draconic21 token budget right now so my agent doesn't hit a 402 error mid-workflow when it tries to call the signal endpoint.”
Technical details
Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/token_budget_check?utm_source=zero.xyzWhen to prefer
Use this endpoint as a lightweight pre-flight check before committing to a more expensive paid signal call (e.g. /v1/signal_latest at $0.03). At $0.01 it is cheaper than any signal endpoint and prevents wasted spend from 402 failures mid-workflow. Prefer it when building agent pipelines that need to gate on budget availability before proceeding.
Side effects
- HTTP 402 if the agent wallet is unpaid or has insufficient balance
- Invalid or malformed POST body returns a 400 error
- Network timeout if the Render.com host is cold-starting
- Missing required fields in the input object cause validation errors
