Canonical machine-readable descriptors: https://solcleus.com/v1/info and
https://solcleus.com/.well-known/x402. Where this file disagrees with them, they are right.

## Start here (free, no credentials)

- [Verified Burst demo](https://solcleus.com/v1/burst/demo): shows an answer that verifies
  and gets charged, and a wrong answer that gets caught and does not. No API key, no wallet,
  no payment. **Read its `honesty` field first** — it states what is real and what is
  stipulated. It is a demonstration, not a live benchmark: responses are cached ~15 minutes
  (so `latency_s` is from the cached run), the catch scenario's wrong answer is *stipulated*
  to stand in for a hallucination while the judge calls catching it are real and independent,
  and it is limited to 6/IP/day and 500/day overall.

## Verified Burst — pay-per-checkable-decision inference for agents

Samples best-of-N and settles a service fee over x402 ONLY when the verifier passes. A miss
is free. Your provider-key token costs are billed to you directly and are not marked up.

Pricing: the base is $0.004 ($0.002 burst + $0.001 candidates + $0.001 verify) and **scales
with configuration** — more samples or a stronger verifier costs more. The demo's confirm
scenario (n=3, independent judge) reports $0.0045. Both are correct; they are different
requests. Quote your actual request before committing.

Keys and wallets: a **funded wallet is required** — that is the spend ceiling, enforced
on-chain rather than by our promise. A provider key goes in the `X-Provider-Key` header and
is used for generation only. Your **first 3 bursts can run without a provider key**, on ours
(`free_trial_bursts: 3`, per wallet, payment still validated); after that, bring your own.

Settlement: x402 on Base mainnet (eip155:8453), USDC, through a facilitator we run ourselves
rather than a third-party service. Honest caveat: settlement is normally confirmed against
the chain, but if the RPC endpoint is unreachable the broker resolves the receipt as
`unknown` and trusts the facilitator rather than block a legitimate payment. On-chain
confirmation is the normal path, not a guarantee on every request.

Verifier modes (`verifier`), which decide whether you are charged:
`self_consistency` (N-of-M samples agree; pair with `answer_key`, or agreement is measured on
full answer text and rarely matches on prose) · `judge` (adversarial LLM check) ·
`independent_judge` (a different model family, decorrelated from your model's blind spots) ·
`independent_quorum` (multiple model families agree, k-of-M — independent of your model, but
reached through one upstream account, so not independent of our infrastructure) ·
`none` (no gate, always charged). Pass a `candidate` to verify your agent's own answer with
no generation.

MCP server: `pip install verified-burst`, command `verified-burst`, tool `buy_verified_burst`.

## Records anyone can check

- [GET /transparency.json](https://solcleus.com/transparency.json): append-only log state.
- [GET /.well-known/solcleus-attestation](https://solcleus.com/.well-known/solcleus-attestation):
  the Ed25519 public key every signed result verifies against.
- [GET /catalog.json](https://solcleus.com/catalog.json): published results, **opt-in only** —
  nothing appears here that the submitter did not agree to publish.

## Human pages

- [Front page](https://solcleus.com/): what Solcleus accepts and how it charges. Job
  submissions start here. Replies are written and sent **by hand, by one person** — there is
  no automated mailer, so allow several days. A declined job is told which gate it missed.
