Ethereum RPC (chain 1): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units.

Mode RPC (chain 34443): JSON-RPC over HTTPS on NodeFlare's own bare-metal nodes. Pay per request in USDC, no account or API key - built for AI agents. All methods including eth_getLogs, eth_call, trace, and debug (archive) - good for indexing, event queries, and simulation. Simple calls $0.001; heavy calls priced by compute units. One of the first independent x402 RPC providers for this chain.

Should my agent pay these x402 endpoints? Up to 25 listings from nohumans.directory in one call: pay, caution or avoid for each, with plain reasons, including whether we bought it with real USDC and it delivered.

Api EndpointProvider: api.nohumans.directory

Should my agent pay this x402 endpoint? For any listing in nohumans.directory (id from /v1/discover), one call returns pay, caution or avoid with plain reasons: probe history and latency, whether its payment address is stable, whether we bought from it ourselves and it delivered (with the on-chain tx), its on-chain payments in the last 30 days, and whether the live price matches the listed one. Check before spending on an unfamiliar paid API.

NomiCheck payment receipt: cross-checks the liquidation, the frozen FX snapshot and the on-chain transfer. Ed25519-signed output with the legal-rules hash and the date they were verified.

Api EndpointProvider: nomicheck.ynt.codes

Full unclaimed-crypto report for one wallet: which open airdrops, reward distributions, refunds and forgotten balances it can still claim (Uniswap 2020 UNI, Merkl on Ethereum/Base/Arbitrum/Optimism/Polygon, Doppler XDP, Drift recovery, CAPX, defunct-DEX ETH, Polymarket unredeemed winnings, Uniswap v3 uncollected LP fees, Solana rent in empty token accounts), with amounts, USD estimates, deadlines and official claim links. Read-only. Wallets with zero open claims are refused before payment.

Rolling index of NIP-90 Data Vending Machine activity on Nostr. Shows what AI/data services agents are paying each other for right now — the sats-denominated agent-economy leading indicator. Per-kind breakdown of requests, responses, unique customers, unique providers. Query ?window=15m|1h|6h|24h.

Api EndpointProvider: nostrpulse.xyz

Collects kind 9735 zap receipts addressed to one public key over up to twelve relays, merges them by event id and reports who sent how much over the requested window. Every amount comes from decoding the BOLT-11 invoice carried in the receipt, not from the amount tag of the zap request, because the two can disagree and only the invoice was payable.

Api EndpointProvider: nostr.halowerk.com

Accepts three forms of recipient. A bech32 lnurl is decoded to its callback URL, a Lightning address is resolved through the well-known lnurlp path, and a Nostr public key is resolved by reading its kind 0 profile from relays and taking the lud16 or lud06 field it publishes.

Api EndpointProvider: nostr.halowerk.com

Takes any public NIP-19 identifier or a 64-character hex value and returns every representation it can be expressed as. A decoded nprofile or nevent yields not only the key or event id but also the relay hints, the author and the kind that the TLV form carries — precisely the fields that make a follow-up query targeted, and precisely what is lost by code that only handles npub.

Api EndpointProvider: nostr.halowerk.com

Takes a kind 9735 receipt directly or fetches it from relays by event id, then runs eight named checks and reports each one separately with its reason. The receipt signature and the signature of the zap request enclosed in the description tag are verified per BIP-340. The invoice is decoded and its amount is compared against the amount tag of the zap request, since those two can disagree and only the invoice was payable.

Look up a company by its website domain and get the most comprehensive company profile. This is the easiest way to get rich company data if you know the company's website. Multi-source data is aggregated from professional networks, business databases, and other sources.

Api EndpointProvider: np.orthogonal.com

Search emails based on a website domain. Returns all email addresses found on the internet for a given domain, with organization info and employee details.

Api EndpointProvider: np.orthogonal.com

Returns comprehensive hourly precipitation data for the given time range and location(s). Each hour includes precipitation amount, type (rain/snow/mixed), probability (for forecasts), and data source. Seamlessly combines historical observations with forecast data depending on the requested time range. | ERROR: Unable to calculate price.

Api EndpointProvider: np.orthogonal.com

Search and discover companies using a LinkedIn Sales Navigator search query. Returns paginated results. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.
