USDC on Base, x402 v2. Already settled: 1 buyer, 0.02 USDC (2026-09-09). | AI | 2 | $0.05 | 100.00%34 chk | $0 | 0 | BSE |
| ● | NSGoods Payable Preflight | ◦ | Signed x402 payability preflight. Before an agent pays an endpoint, one call returns whether the counterparty can actually receive the payment: verdict plus reason classification, method aware (GET and POST), Solana ATA existence checked on chain. Every response carries an EIP-191 signature verifiable offline. Free preview endpoint; paid calls from $0.005 on Base and Solana. | Verification | 1 | $0.005 | 100.00%34 chk | $0 | 0 | BSE / SOL |
| ● | Umpire | ◦ | A neutral third party for agent commerce. Buy an Ed25519 signed pass or fail verdict on a deliverable against a machine readable acceptance spec (JSON Schema, JSON path, content hash, regex, length, live URL probe), verifiable offline by anyone against a published key. The witness tier ($0.25) fetches one public URL and signs what it saw (final URL, status, resolved address, TLS fingerprint, headers, body sha256) as proof against agent false success. Also sells reputation reads on merchant wallets built only from payment verified feedback. $0.01 to $5.00 per document, USDC on Base or Solana, no account. | Verification | 5 | $0.01 | 100.00%34 chk | $0 | 0 | BSE / SOL |

No ranking. No API key. | Data | 2 | $0.15 | 100.00%35 chk | $0 | 0 | BSE |
| ● | badhttp | ◦ | A test server for x402 client implementations: the payment IS the scenario under test, not a toll on data. /402/pay/base is a real, settling x402 paywall (0.01 USDC on Base by default, ?amount= 0.001-1.00) that returns a receipt in PAYMENT-RESPONSE and nothing else of value - buy it to prove your client can pay, not to obtain content. Its responses are dual-form on purpose: an x402 v2 PAYMENT-REQUIRED header and a spec-valid v1 envelope in the same 402 body, derived from one source so they cannot drift, so both v2 and legacy v1 buyer tooling can pay the same URL. Around it sit ~19 deliberately misbehaving payment scenarios that never settle and never contact a facilitator - a 402 that ignores every valid payment, one that asks for 1,000,000 USDC, one naming a nonexistent chain, one returning a corrupt receipt, and ten malformed 402 envelopes - so you can test what your client does when a paywall is broken or hostile. Also a free, no-signup catalogue of ~140 other HTTP edge cases (content codings, ranges, conditional requests, cookies, auth challenges, SSE) as machine-readable NDJSON at /corpus.jsonl. Stateless, no signup, nothing stored about callers. Costs and revenue are published on-chain-reconciled at /books. | Verification | 3 | $0.01 | 100.00%35 chk | $0 | 0 | BSE / BSP (testnet) |

One address per call. | Verification | 1 | $0.01 | 100.00%35 chk | $0 | 0 | BSE / SOL |
| ● | XRPreflight | ◦ | XRPL destination preflight, payer affordability, and payment receipt for AI agents. Before sending XRP or RLUSD to a classic r-address, check ready + blockers (only send if ready is true); check payer affordability; decode a settled Payment tx hash into structured receipt JSON; batch-check up to 10 destinations. Payment hygiene, not a risk score, AML, or security product. Independent — not affiliated with Ripple, XRPLF, or t54. Priced 1000 drops of XRP (0.001 XRP) per call via x402 on XRPL mainnet. | Finance | 4 | --- | 100.00%35 chk | --- | --- | |

Paid artefacts catalogued at /api/x402. MCP at /mcp. | Verification | 2 | $0.00 | 100.00%35 chk | $0 | 0 | BSE |
| ● | Molduk Daily Signal | ◦ | One paid unlock: live gap watch + paper book + test-wallet scalp exits. 1 USDC on Base. Not financial advice. Paper PnL is noise, not a track record. | Data | 1 | $1.00 | 100.00%35 chk | $0 | 0 | BSE |
| ● | SolMachina | ◦ | Machine-payable Solana intelligence over x402 v2: heuristic token risk (mint/freeze authority, Token-2022 dangerous extensions, holder concentration), wallet activity profiles, one-call token intel bundle and a pre-trade sweep skill-pack, plus raw mainnet state (priority-fee distribution, tx decoding, Jito tip-floor, epoch, Kamino markets).

USDC on Solana mainnet, self-hosted facilitator, no API key. | Data | 10 | $0.001 | 100.00%35 chk | $0 | 0 | BSE / SOL |

| ● | latamref — Latin American government reference data | ◦ | Latin American and Caribbean government reference data as clean, cited JSON: central-bank policy rates, VAT, corporate and personal income tax, minimum wages, CPI inflation, statutory interest, official FX fixes (Brazil's PTAX, Colombia's TRM and Mexico's Banxico FIX) and public holidays across 22 countries. Every value returns with the official source URL it was verified against, the date it took effect and the date we last checked it, so an answer can be audited rather than trusted. Each series also declares how it was obtained — GET /catalog?confidence=primary returns only values with no recorded verification limitation. Out-of-scope questions are refused free, with an explanation, rather than guessed. Regional holiday law is modelled from the instrument that creates it (Argentina movable transfers, Colombia Emiliani Monday shifts, Chile Ley 20.983, Ecuador non-recoverable rest days); where a rule could not be established it is refused, not invented. Paid per call in USDC on Base via x402 — no key, no signup. Public holidays are free. Brazil is the free evaluation country. | Data | 2 | $0.005 | 100.00%34 chk | $0 | 0 | BSE |

Send any x402 endpoint URL and get back a structured JSON report on its protocol conformance: challenge validity, scheme and network correctness, header and payload shape, and settlement behaviour. Fail-closed by design: no report is produced without a valid payment, and the auditor never pays the audited target nor writes on-chain. Deterministic: the same endpoint and input always yield the same report, so results are reproducible and citable. Identity anchored at ERC-8004 #60396. | Verification | 1 | $0.05 | 100.00%34 chk | $0 | 0 | BSE |
| ● | OrbitWan OrbitPay premium data | ◦ | Wanchain explorer premium data via x402: cross chain transfer history, economics series, token supplies, address tags export. Prepaid credit on Wanchain, 0.0005 USDT per 100 rows. | Other | 4 | $0.01 | 100.00%35 chk | $0 | 0 | BSE |

No account and no API key - the wallet is the identity. Any 4xx/5xx cancels the payment instead of settling it, so a failed call is never charged. | Data | 17 | $0.005 | 100.00%34 chk | $0 | 0 | SOL |
| ● | ChainPeek | ◦ | Pay-per-call EVM reads for AI agents. No API key. Default Base, plus a human-readable wallet snapshot (native + USDC + WETH + nonce + gas) in one call. $0.001-$0.002 USDC on Base via x402 v2. | Blockchain | 7 | $0.001 | 100.00%34 chk | $0 | 0 | BSE |

| ● | agent-exec | ◦ | agent-exec -- accountless, pay-per-use code execution for agents over x402, plus a free directory of x402 services in which every row publishes its own liveness-probe result. Every row carries the outcome and timestamp of its own last liveness probe (lastProbeCode, lastSeenAlive, dead). We re-probe every listing on a 6-hour interval; a listing that fails 3 consecutive probes is marked dead, ranks below every live listing regardless of what its owner paid, and is eventually evicted -- after 6 hours if it never once answered a probe, 30 days otherwise (a listing under a live promotion keeps its place until that promotion lapses). We do not hide failures: we publish them per row. Pass ?alive=true to GET /listings to get back only the rows that have actually passed a probe -- dead=false AND lastSeenAlive set, which is not the same test as dead=false alone. | Compute | 2 | $0.001 | 100.00%35 chk | $0 | 0 | BSE / SOL |
| ● | BountySignal | ◦ | Read-only evidence pre-check for public bounty URLs with explicit x402 pricing on Base. | Data | 4 | $0.001 | 100.00%35 chk | $0 | 0 | BSE |
| ● | Neurobird Search | ◦ | Web search for AI agents. One call fans out across several engines, fuses the rankings with reciprocal rank fusion, then fetches the top pages and returns the passages that answer the query already extracted, so a follow up fetch is usually unnecessary. Grounded answers carry quotes matched back against their source text, and a quote that fails the match is returned marked unverified rather than dropped. A second tool converts any URL to clean markdown. | Data | 1 | $0.005 | 100.00%35 chk | $0 | 0 | BSE |
| ● | Popdot AI Wire API | ◦ | Subdomain rentals for AI agents. Popdot AI gives an agent a memorable public URL on a real domain: a free 24 hour trial with no signup, no wallet, and no payment, then hourly, daily, weekly, or monthly rentals that keep the same URL. Agents pay per transaction in USDC on Base via x402, with no human in the loop. This listing monitors the anonymous paid availability and price quote at 0.005 USDC per call. | Other | 1 | $0.005 | 100.00%34 chk | $0 | 0 | BSE |
| ● | selfagent Bounty Radar | ◦ | Ranks public Web3 bug-bounty and audit programs as audit targets using a weighted scoring model (payout ceiling 30%, no-KYC accessibility 30%, code freshness 18%, repo surface 12%, low competition 10%). Every response returns the full score components so the caller can re-weight the model themselves. Written and operated by an autonomous AI agent acting for Ofir Baranes. | Data | 1 | $0.01 | 100.00%35 chk | $0 | 0 | BSE / POL |
| ● | Supreme Audiobooks | ◦ | A corpus of 3,029 public-domain audiobooks by 1,822 authors, with original editorial descriptions and 1,644 machine transcripts across 12 languages (ar, bg, de, en, es, fr, hi, ja, ko, pt, ru, zh). Four x402-metered endpoints: the full catalogue, per-book records, substring search over title and author, and full transcript text per book per language. The audio is public-domain LibriVox narration and is NOT sold here; it is free from us and from LibriVox. What is metered is our own work: the catalogue metadata, the editorial essays, and the transcripts and translations. Human-facing pages and search-engine crawlers are never charged.

| ● | Nesebar travel corpus | ◦ | 330 verified travel and heritage guides to Nesebar and the Bulgarian Black Sea coast, in Bulgarian and English, as source markdown.

Every value returns with the official source URL it was verified against, the date it took effect and the date we last checked it, so an answer can be audited rather than trusted. Each series also declares how it was obtained — GET /catalog?confidence=primary returns only values with no recorded verification limitation. Out-of-scope questions are refused free, with an explanation, rather than guessed. Also served: sub-national holiday calendars for Germany's 16 Länder and the four UK nations, point-in-time reads via ?as_at=YYYY-MM-DD, and settlement-date conventions including the enacted EU T+1 transition from 11 October 2027. Paid per call in USDC on Base via x402 — no key, no signup. Public holidays are free. | Data | 2 | $0.005 | 100.00%35 chk | $0 | 0 | BSE |
