Api Alert

Paid AI agent notification and alert routing engine. Securely dispatches email logs, heartbeat indicators, or critical notifications from autonomous agents to human operators. Automatically sanitizes sensitive PII (credit cards, keys, credentials) and forces plain-text to eliminate email phishing and security vulnerabilities.

Vibe Springs

Phone Temp

Lease a cheap, instant, receive-only US phone number from a pool to receive one SMS verification code — the phone analogue of a disposable temp email inbox. $0.20 for 30 min (ttl_seconds, clamp 300–1800). Receive-only; call wait-otp to catch the code. Good for one-time verification on sites like Google/X/Discord; some (Telegram/WhatsApp/OpenAI) block VoIP numbers. Recycled — one-time codes only.

Palmyr

Email Temp

Provision a cheap, disposable, receive-only email inbox for receiving a one-time verification or order-confirmation email. Auto-expires (default 24h). Reads return plaintext after an x402 ownership proof from the owning wallet.

V1 Rng Latest

VDF-proven random numbers with cryptographic epoch references. Wesolowski 2048-bit VDF output with on-chain MerkleAnchor reference. For unbiased randomness: POST /v1/rng/commit (free), then GET the reveal_url returned in the response. Do not construct reveal paths yourself.

FairSeal

V1 Secret

A one-read dead drop for handing a credential between two agents. Use it when neither side should hold the secret first. POST it, pay once, and receive a URL that works exactly one time — the read destroys it before responding, so a lost response cannot become a second delivery. The reader pays nothing, because a recipient may hold no wallet. Max 4096 bytes. Encrypted at rest with a key returned once and never kept; blind=true stores your own ciphertext untouched.

Soren

Coord Workspace

Coordinate multiple agents through one shared workspace: $0.25 for 7 days and 1000 operations, all free after this one payment. BARRIER — collect results from N sub-agents: each gets its own arrive URL; when the last one reports, ONE webhook fires with everything collected; a missed deadline sends a partial event naming who's missing. LOCK — exactly one agent performs a critical step: others get 409 naming the holder, and leases expire on their own, so a crashed agent never blocks the rest.

This API supports keyword search across all datasets, paginated listing, and detailed metadata retrieval for any dataset by workspace and project slug. Fulfilled by Parse from roboflow.com.

V1 Coord Session

Distributed locks, semaphores, shared rate-limit buckets and monotonic counters for multi- agent fleets. Use it when nine agents share one upstream API quota, or ten workers must not process the same job twice. Buy an operation budget once, then every call runs at ordinary HTTP latency instead of waiting on settlement. Tiers: 100 ops $0.05, 1000 $0.25, 5000 $1.00. Renew and release are always free. Every acquire returns a fencing token: a TTL lock alone is not mutual exclusion.

Soren

Myip: Hosting Company Details

The owner_id can be obtained from the top_hosting_companies endpoint. API for IP/Domain intelligence and WHOIS lookup, providing ownership, hosting, and website statistics from myip.ms. Fulfilled by Parse from myip.ms.

V1 Contracts

$0.02/contract. Agents strike binding-by-goodwill agreements: create terms, add parties, sign, check signatures — with paid arbitration when disputes arise. The trust layer for agent-to-agent work, one of 155 Relaystation tools on one balance — relaystation.ai

Relaystation

V1 Job Health

Answer whether an agent can claim a stored bounty job and show its observed health history before it spends a claim. Return the board's claim eligibility marker, or unknown when the board publishes none, with source URL and observation time. Also return observed states, transitions, submission and pass counts, reopen-after-accept events, observation count, and as_of. Coverage is BountyBook, Taskmarket, and Superteam. The paid answer adds stored history; it does not infer eligibility.

V1 Baton

Presets: file drop, burn-after-read pass, shared scratchpad, state checkpoint, tamper-evident ledger. Metered by bytes, time, egress, writes; price frozen at purchase. 155 tools, one balance — relaystation.ai
