Bounty Engineer Purchase Rescue
x402
Bounty Engineer Purchase Rescue is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-12).
Analyzes a history of failed purchase attempts and returns a safe, step-by-step rescue decision to guide an autonomous agent through recovering from an ambiguous or stuck payment flow without repeating irreversible transactions.

How this service works
Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.
Output
Returns a structured JSON object with a rescue decision (e.g. 'inspect_prior_side_effect', 'safe_to_retry', 'abort'), ordered recovery steps, any blockers or warnings, a repeat-intent flag, an optional retry delay in milliseconds, an incident SHA256 fingerprint for auditability, the observed attempt count, estimated price, and remaining budget — with explicit limitations noting that no external wallets or facilitators are queried and no actual payment is executed.
Example use cases
Double-payment prevention after timeout
“My autonomous agent tried to pay for an API call, got a timeout, tried again, and now I'm not sure which one actually settled. I have $0.08 remaining budget and a $0.01 max per call — analyze those two attempts and tell me if I'm about to double-pay.”
Stuck agent spend-policy rescue
“My agent is stuck in a retry loop on a paid API — it's made 5 attempts so far, the max I want to spend is $0.015, my remaining budget is $0.05, and side effects are definitely possible. Give me a rescue plan so it doesn't fire another irreversible transaction.”
Post-failure incident audit before reauthorization
“Before I let my agent sign another payment, I want to audit the 3 failed purchase attempts it already made — budget remaining is $0.12, max price is $0.009, and I'm not sure if any of those had side effects. What's your decision: retry, abort, or inspect?”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/purchase-rescue?utm_source=zero.xyzWhen to prefer
Use this endpoint when an autonomous agent has made one or more ambiguous or failed payment attempts and needs a safe, structured decision on whether to retry, abort, or inspect for prior side effects — especially when irreversible transactions (e.g. on-chain payments) are involved and double-spending must be avoided. Prefer this over ad-hoc retry logic whenever a spend policy with budget caps must be enforced and there is meaningful uncertainty about whether a prior attempt settled.
Side effects
- Missing required policy fields (max_price_usd or remaining_budget_usd) returns a validation error
- Empty or malformed attempts array (must have 1–40 items) causes schema rejection
- If side effects cannot be determined from caller-supplied observations, decision defaults to 'inspect_prior_side_effect' conservatively
- No actual payment settlement verification is performed — decision is advisory only
- Ambiguous caller-supplied observations may yield conservative warnings rather than a clear retry decision
