## Services

- [Umpire Witness Verdict](https://www.zero.xyz/c/umpire-witness-verdict-e32ddcba/llms.txt): $0.25/call via x402. Probes a live public URL against your expectation and returns a cryptographically signed Ed25519 verdict with network-level evidence (TLS fingerprint, resolved address, response headers, body hash, timestamp).
- [Umpire Basic Verdict](https://www.zero.xyz/c/umpire-basic-verdict-5e42ddba/llms.txt): $1/call via x402. Returns a signed pass/fail verdict document verifying a deliverable against deterministic acceptance checks (JSON Schema, JSON path, content hash, regex, length bounds), suitable as escrow-release evidence.
- [Umpire Probe Verdict](https://www.zero.xyz/c/umpire-probe-verdict-6c952326/llms.txt): $2/call via x402. Runs up to three live network probes (HTTP status, keyword, CSS selector, JSON path) against public URLs alongside other checks, returning an Ed25519-signed pass/fail verdict for verifying delivered work before releasing escrow.
- [Umpire Sworn Verdict (Double-Pass Async)](https://www.zero.xyz/c/umpire-sworn-verdict-double-pass-async-9c04c87d/llms.txt): $5/call via x402. Runs a deliverable through all acceptance checks twice, spaced ~1 minute apart, and issues a cryptographically signed pass/fail verdict only if both passes succeed — designed for ERC-8183 escrow release evidence.

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