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 audit report including: total observed billed USD, budget overage amount, count of failed events, groups of repeated idempotency keys flagged as potential duplicates (with duplicate charge estimate), a ranked list of expensive tools, whether the caller's budget was exceeded, a SHA-256 hash of the input for integrity, and a list of actionable recommendations. Also includes a limitations disclaimer noting amounts are caller-supplied and not settlement-verified.
Example use cases
Detecting duplicate web extraction charges
“I think my agent called the same web extraction tool twice in run 'scrape-job-7' with the same idempotency key, each billed at $0.05. Can you audit those events and tell me if there are duplicate charges I should investigate?”
Enforcing per-run budget compliance
“My agent run 'data-pipeline-3' logged 5 tool calls totaling $0.12, but my max allowed spend was $0.08. Audit these events and tell me which tools pushed me over budget and what I should do differently.”
Identifying most expensive tools in a session
“Here are 10 tool-call events from my agent session 'analysis-run-42' — can you analyze them and rank which tools are costing me the most so I know where to optimize?”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/agent-run-cost-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to post-process a batch of agent tool-call telemetry events to detect budget overruns, duplicate billing, and expensive tool patterns within a single agent run. Prefer it over manual log inspection when you have structured cost events with idempotency keys and want algorithmic duplicate detection plus recommendations. Not a substitute for verified settlement data — it works on caller-supplied cost figures.
Side effects
- Missing required 'events' array in body returns validation error
- Empty events array (minItems:1 violated) returns schema error
- cost_usd field with negative value rejected by minimum:0 constraint
- Exceeding 250 events (maxItems) returns rejection
- Malformed run_id or tool fields may result in incomplete grouping
- Payment not included or insufficient USDC causes x402 payment required response
