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
A markdown-formatted document containing either a full bounty radar (list of relevant bounty opportunities matching the topic, scored or ranked) or an AI-generated bid draft tailored to the provided job brief or scene — delivered after x402 micropayment verification on Base.
Example use cases
Freelancer scanning niche bounties
“Search for open bounties on the topic 'Solidity smart contract auditing' and show me the top 5 results from the full radar.”
Agent drafting a project bid
“Write a bid draft for this job brief: 'Looking for a technical writer to document a DeFi protocol's API and onboarding flow, 2-week turnaround.'”
Storyboard scene bid generation
“Generate a bid draft based on this scene: 'A lone developer debugging code at 2am with energy drinks — cinematic, moody lighting, indie film aesthetic.'”

Endpoint
POSThttps://x402.devvizion.com/v0/proof-handoffWhen to prefer
Choose this endpoint when an AI agent needs to discover bounty opportunities or generate a bid proposal without a subscription, paying only per call in USDC via x402 on Base. It is especially useful for freelance or research agents that need on-demand radar sweeps or one-off bid drafts rather than recurring access.
Side effects
- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Invalid or missing topic/brief field — returns malformed or empty radar
- Pack ID not found — no results returned for /v0/pack lookups
- Rate limiting or upstream service unavailability — timeout or 503
- Scene or brief too vague — low-quality or generic bid draft generated
