# Bounty Engineer Schema Sample Endpoint

> Bounty Engineer Schema Sample Endpoint is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Generates a deterministic structural example (sample) from a submitted JSON schema object, returning a hashed sample payload.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bounty-engineer-schema-sample-endpoint-3f7af27c -d '<json body>'
```

Example prompt: Generate a structural sample from this JSON schema for me — I want to see what an example payload looks like: {"type":"object","properties":{"userId":{"type":"string"},"count":{"type":"integer"}}}

## When to prefer this

Use this endpoint when you need a fast, deterministic, structural sample from a JSON schema — particularly useful during API development, agent pipeline testing, or fixture generation. Prefer this over manual mock creation when you want a hash-verified, reproducible example payload. Not suitable when you need semantically valid or domain-realistic data (e.g. real-looking names, addresses, or financial figures).

## Known failure modes

- Missing or malformed schema input returns an error or empty sample
- Schema with deeply nested or recursive references may produce incomplete structural samples
- Semantic validity of generated values is not guaranteed — only structural shape is reflected
- Network/hosting issues on Render may cause timeouts or 502 errors
- Overly complex schemas may result in truncated or simplified sample output

## 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: 'ok' boolean, 'mode' string set to 'schema_sample', a 'sample' object that is a deterministic structural example generated from the input schema, a 'limitations' array describing caveats (e.g. no guarantee of semantic validity), and a 'sample_sha256' string hash of the sample for integrity verification.

## Request schema (JSON Schema)

```json
{
 "type": "object",
 "properties": {
  "schema": {
   "type": "object"
  }
 }
}
```

## Response schema (JSON Schema)

```json
{
 "type": "json",
 "example": {
  "ok": true,
  "mode": "schema_sample",
  "sample": {
   "id": "example",
   "count": 1
  },
  "limitations": [
   "Generates a deterministic structural example only; it does not guarantee semantic validity beyond simple schema hints."
  ],
  "sample_sha256": "b6f7faf776f39d0edfb0dde50fc1ba0e4680c091d639a24f9c7f5740c008ad95"
 }
}
