How this service works
Free sample bounty radar, then paid full radar (0.015 USDC) or bid draft (0.01 USDC) on Base via x402. No subscription.
Output
Returns a Markdown-formatted document containing either a full bounty radar (list of relevant bounty opportunities for the given topic) or a bid draft (structured proposal based on the provided job brief), depending on the inputs supplied. The response is scoped to the paid tier after x402 micropayment settlement on Base.
Example use cases
Bounty radar for niche research topic
“Pull a full bounty radar for the topic 'zero-knowledge proof tooling' and give me the top 8 results — I want to see what bounties are active in that space right now.”
Bid draft from freelance job brief
“I have this job brief: 'Design and deploy a REST API for a loyalty points system using Node.js and PostgreSQL' — can you draft a bid proposal I can submit for it?”
Change-order doc for expanded project scope
“My client just asked me to add a mobile app to a web-only project — write me a change-order document using this brief: 'Original scope was a web dashboard; client now wants iOS and Android apps with push notifications included.'”
Technical details
Endpoint
POSThttps://x402.devvizion.com/v0/change-orderWhen to prefer
Choose this endpoint when you need a per-call, no-subscription bounty radar or bid draft generated on demand and are willing to pay a small USDC micropayment (~0.01–0.015 USDC) via x402 on Base. Prefer this over subscription-based alternatives when call volume is low or sporadic, or when building an agent that needs to autonomously discover bounties or compose bids without a recurring commitment.
Side effects
- Payment not settled via x402 — returns HTTP 402 with payment details required
- Missing required topic or brief field — returns error indicating insufficient input
- Invalid packId — endpoint may return empty or error response
- Topic too vague — radar may return low-quality or sparse results
- Network or Base chain latency causing payment confirmation delays
