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 JSON object containing a machine-ready delegation contract with the specified objective, budget, deliverables, constraints, acceptance rules, required capabilities, due date, and a deterministic SHA256 hash of the contract for integrity verification. Also includes a mode label, version string, and a limitations notice clarifying that the contract is caller-specified and does not guarantee remote agent compliance.
Example use cases
Structured contract for price extraction task
“Build me a delegation contract for an agent that needs to extract three verified product prices from the web — budget capped at $0.50, due October 2nd at noon, deliverable is a JSON array of three products, and the acceptance rules should check that items length is at least 3 and currency is USD. The agent will need web-research capability.”
Bounty task contract for GitHub issue resolution
“Create a delegation contract pack for an agent working on a GitHub bounty: the objective is to fix a failing CI pipeline, constraints are no changes to production configs, deliverable is a passing test suite link, required capability is github-operations, max budget $5.00, due in 48 hours.”
Agent sub-task contract with spend controls
“I need a machine-ready delegation contract for a sub-agent that will summarize 10 research papers — objective is to produce structured summaries, deliverable is a JSON array of 10 summary objects, acceptance rule is that the array length is at least 10, max budget $2.00, due by Friday noon, required capability is document-analysis.”

Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/delegation-contract-pack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically generate a deterministic, SHA256-verifiable task contract for an autonomous agent — especially when you need structured acceptance rules, budget caps, capability requirements, and a machine-ready flag in a single atomic response. Prefer this over ad-hoc prompt-based task assignment when auditability, integrity verification, or inter-agent delegation handoffs are required.
Side effects
- Missing required 'deliverables' or 'acceptance_rules' fields returns a validation error
- Exceeding maxItems limits on constraints (30), deliverables (30), acceptance_rules (50), or required_capabilities (50) causes rejection
- Malformed 'due_at' date string may produce an invalid contract
- Negative max_budget_usd value fails minimum:0 validation
- Payment failure (HTTP 402) if USDC payment is not provided or is insufficient
- Service unavailability on the Render host returns 5xx errors
