Pay-per-call utilities for autonomous agents: exactly-once action keys, a secret vault, meeting memory, token compression, scraping, PDF parsing and x402 endpoint verification.

Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"agentic-endpoints-agentic-endpoints","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Pay-per-call utilities for autonomous agents: exactly-once action keys, a secret vault, meeting memory, token compression, scraping, PDF parsing and x402 endpoint verification. Every skill here is also a plain HTTP route. Unlike most paid A2A agents, the paid skills ARE callable over A2A: send an X-Credit-Token header, and get one free with no account at POST /credits/trial.
/once-key — Atomic idempotency witness — claim an action exactly once, record its result, and replay that result to every later caller Costs $0.001.
/scrape — Web scraping and text extraction Costs $0.005.
/pdf-parse — PDF text extraction Costs $0.01.
/compress — Token compression for LLMs Costs $0.005.
/vault/store — Store an encrypted item in the vault. The first store claims the namespace and returns a one-time namespace_token. Costs $0.02.
/vault/delete — Delete an item from the vault (requires the namespace_token) Costs $0.005.
/meetings/import — Import a meeting transcript. Accepts a raw WebVTT or SRT export straight from Zoom, Teams, Meet or a notetaker -- timestamps and cue numbering are stripped so search matches phrases the export split across cues. visibility "private" stores ciphertext this service cannot read; "queryable" stores plaintext and indexes it for search. The first import claims the namespace and returns a one-time namespace_token. Costs $0.004.
/meetings/search — Full-text search across your queryable meetings. Returns ranked excerpts, and reports how many meetings were private and therefore not searched. Costs $0.006.
/x402/verify — Before paying a stranger's x402 endpoint, read its live payment challenge and compare it against every previous observation. Flags a changed receiving address, network or asset as critical drift. Reports what the endpoint declares; it does not certify the operator. Costs $0.003.
/meetings/summarize — Ask a question in plain language and get an answer grounded in your own meetings, with a citation to the meeting each claim came from. Retrieves the relevant transcripts and reasons over them. When nothing matches, no answer is generated rather than one being invented. Costs $0.030.
/meetings/get — Fetch one meeting in full, by meeting_id (requires the namespace_token) Costs $0.002.
/meetings/list — List the meetings in a namespace with their metadata, newest first. Never returns transcripts (requires the namespace_token) Costs $0.001.

— Delete a meeting and remove it from the search index (requires the namespace_token) Costs $0.001.
/vault/list — List the keys held in a vault namespace with their metadata, without returning any ciphertext (requires the namespace_token) Costs $0.001.
/vault/exists — Check whether a key exists in the vault without returning its ciphertext (requires the namespace_token) Costs $0.001.
/vault/retrieve — Retrieve an encrypted item from the vault (requires the namespace_token issued at claim time) Costs $0.02.
/once-key/complete — Stores the result of work performed under a claim. Later claims of the same action_key return status "duplicate" together with this result, so the caller that lost the race can continue instead of repeating the side effect. Free: the claim price covers the whole lifecycle. Completion is final and cannot be overwritten. Free.
/vault/rotate-token — Mints a new namespace_token and invalidates the current one, which must be presented to authorize the rotation. Free on purpose: charging for the correct response to a suspected leak is how you end up with callers who never rotate. There is no recovery if the token is lost — any such path would be a second way into the namespace and would serve an attacker just as well as the owner. Free.
/once-key/release — Frees a claimed action_key so a retry can proceed immediately rather than waiting out the lease. Free. Refuses with 409 if the key was already completed, since releasing it would discard the recorded result and permit a second side effect. Free.
/credits/trial — Returns a credit token carrying a $0.10 balance — about 20 calls — immediately, with no account, no email, no wallet and no approval step. Send it as X-Credit-Token on any paid endpoint exactly like a purchased one. Takes no request body. One allowance per client address: calling again returns the same token and whatever balance remains, so retrying is safe but does not top the balance up. It exists because paying per call requires a funded wallet first, which asks a caller to commit money befo…
/credits/balance — Returns the remaining balance for a credit token, and what it has been spent on. Free, and takes no request body: the token goes in the X-Credit-Token header. Charging a buyer to find out how much they have left would be a good way to never sell them a second one. Free.
