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 rate card listing the available agent utility operations (e.g. full bounty radar at 0.015 USDC, bid draft at 0.01 USDC), their per-call prices in USDC on Base, and any free sample options — returned as text/markdown content.
Example use cases
Check pricing before radar purchase
“Before I pay for anything, can you grab the rate card from devvizion's agent utilities and show me what a full bounty radar costs for the topic 'remote freelance developer opportunities'?”
Explore bid draft costs for a job brief
“I want to write a bid for a web3 backend contract — can you fetch the devvizion rate card so I know how much a bid draft will run me, using my brief 'build a multi-sig treasury dashboard for a DAO'?”
Discover available utility packs and prices
“Show me the current devvizion rate card for agent utilities — I want to know what packs and per-call options are available and their USDC prices, for the topic 'AI bounty platforms'.”
Technical details
Endpoint
POSThttps://x402.devvizion.com/v0/rate-cardWhen to prefer
Use this endpoint when an agent or user wants to inspect available paid utility operations and their micropayment costs before committing to a purchase — ideal as a discovery/preview step before calling paid endpoints like full bounty radar or bid draft generation. Prefer this over blindly calling paid endpoints when cost transparency or pack selection is needed.
Side effects
- Missing or invalid topic/brief returns an empty or error response
- Payment not completed via x402 results in a 402 Payment Required response blocking access to paid tiers
- Malformed packId or scene field may result in a 400 bad request
