Endpoint
POSThttps://x402.devvizion.com/v0/counter-offerWhen to prefer
Choose this endpoint when you need a per-call, no-subscription generated counter-offer in the form of either a bounty radar (competitive opportunity scan) or a bid draft for a specific topic or job brief, and are able to pay micro-amounts (0.01–0.015 USDC) via x402 on Base. Prefer this over subscription-based proposal tools when cost-per-use matters and when the output format (markdown counter-offer) aligns with your workflow.
Side effects
- Payment not received or insufficient — x402 payment gate blocks access and returns 402 with payment requirements
- Missing required topic or brief — endpoint may return an error or empty response without a meaningful input
- Invalid packId — if a pack ID is provided that does not exist, the request may fail or return unexpected output
- Network or Base chain payment failure — transaction not confirmed, resulting in 402 retry loop
- Rate limiting or abuse detection — too many rapid requests may be throttled
